00:00:00This is the Cycle World Podcast. I'm Mark Hoyer. I'm with Kevin Cameron.
00:00:04We're here to talk about the Yamaha V4 MotoGP bike
00:00:07debut. We're going to talk about
00:00:11inline 4s and V4s and flexible chassis.
00:00:18Why we do a V4.
00:00:22Somebody
00:00:22relatively recently did win a championship with an inline 4. V4s are kind of
00:00:27dominant. What are we clutching for here, I guess,
00:00:31is the idea. And why would we try to do this now?
00:00:35And Yamaha is developing this V4
00:00:39for next season, presumably.
00:00:43Whilst in 2027, we would be going to an 850
00:00:47CC displacement limit. Which is a 75
00:00:52millimeter bore limit.
00:00:53So, what
00:00:57are we even doing?
00:00:59So, anyway, I guess we should talk about
00:01:01you want to talk about the
00:01:03debut, Kevin, and just talk
00:01:05about how it did?
00:01:06Well, I want to say a couple of things about
00:01:09why all the fuss.
00:01:12Because
00:01:12here's
00:01:14Fabio Cordero, who
00:01:17is a past
00:01:19time world champion.
00:01:20and since
00:01:22that time
00:01:23he has
00:01:24arrived at the
00:01:27pre-season tests
00:01:28and said,
00:01:29well, we
00:01:30sort of
00:01:31were lacking
00:01:32rear grip.
00:01:34And
00:01:35then the next year
00:01:36they arrive at the
00:01:37pre-season tests
00:01:38and he says,
00:01:39I
00:01:40had hoped that
00:01:41they might have been able to do something
00:01:42about the rear grip
00:01:44and it's
00:01:44kind of holding us back.
00:01:46and
00:01:47he's
00:01:48basically
00:01:49on a life sentence
00:01:51of riding a motorcycle
00:01:52that is
00:01:53lately
00:01:56been
00:01:56in last place.
00:01:59So,
00:01:59I'm sure
00:02:01that people
00:02:02have spoken to him
00:02:03sternly
00:02:04or as they say
00:02:05in Daytona
00:02:06taken him out
00:02:07on the boat
00:02:08about
00:02:11saying things
00:02:12that are critical
00:02:13of the hand
00:02:14that feeds him.
00:02:16Well,
00:02:17that's
00:02:18etiquette.
00:02:20But
00:02:20how does it
00:02:22look for Yamaha
00:02:23to produce a motorcycle
00:02:24that
00:02:25finishes
00:02:26last?
00:02:30That's
00:02:31not a
00:02:32matter that
00:02:33the public
00:02:34relations department
00:02:35would choose
00:02:36to deal with.
00:02:38Now,
00:02:39the supposition
00:02:40is,
00:02:40since everyone
00:02:41else is running
00:02:42a V4,
00:02:43KTM,
00:02:44Ducati,
00:02:45Aprilia
00:02:47and
00:02:48the
00:02:48and
00:02:49Honda,
00:02:51you know,
00:02:53we don't look
00:02:54and say
00:02:55they're all
00:02:56out of step
00:02:56but are Bob.
00:02:59The
00:02:59V4s
00:03:00are
00:03:00getting it
00:03:02done
00:03:03and
00:03:04the one
00:03:05thing we know
00:03:06about the Yamaha
00:03:06that we can
00:03:07see
00:03:08is that
00:03:09it's an
00:03:09inline
00:03:10four.
00:03:12Now,
00:03:13there was a
00:03:14time when
00:03:14the inline
00:03:15four had
00:03:16a definite
00:03:17handicap
00:03:18and that
00:03:19was called
00:03:20piston
00:03:21inertia
00:03:21torque.
00:03:22If you've
00:03:23ever
00:03:23barred,
00:03:24rotated by
00:03:25hand,
00:03:26an inline
00:03:26four,
00:03:27you know
00:03:28that
00:03:28grind,
00:03:30you're pushing
00:03:31the piston,
00:03:31some are going
00:03:32up,
00:03:32some are going
00:03:33down,
00:03:33but when you
00:03:34get so that
00:03:35two are up
00:03:35and two are
00:03:36down,
00:03:36it's real
00:03:37easy and
00:03:39when the
00:03:40engine is
00:03:40running at
00:03:42say 16,000
00:03:44rpm,
00:03:44twice per
00:03:45revolution,
00:03:47all those
00:03:47pistons are
00:03:48stopped
00:03:48and in a
00:03:51quarter of a
00:03:51revolution,
00:03:52which is about
00:03:53a thousandth of a
00:03:53second,
00:03:54they're all going
00:03:55close to 100
00:03:56miles an hour.
00:03:57Now,
00:03:58that exchange
00:03:59of kinetic
00:04:00energy between
00:04:01the pistons
00:04:01and the
00:04:02crankshaft
00:04:03is to a
00:04:05large extent
00:04:06transmitted to
00:04:07the rear
00:04:07tire.
00:04:09And when
00:04:09in desperation,
00:04:11Yamaha went
00:04:12to their
00:04:13one-man
00:04:15tiger team,
00:04:17Masao
00:04:17Furusawa,
00:04:19and said,
00:04:19fix it,
00:04:22fix,
00:04:22fix.
00:04:23And
00:04:24he's a
00:04:26noise,
00:04:27vibration,
00:04:27and harshness
00:04:28guy
00:04:28by training.
00:04:32So,
00:04:33he looked
00:04:33at this
00:04:34and he
00:04:34said,
00:04:34well,
00:04:34let's build
00:04:35a 90-degree
00:04:36engine,
00:04:36which will
00:04:37be like
00:04:38a V4
00:04:40in that
00:04:41half of the
00:04:42pistons,
00:04:43when a
00:04:44piston is
00:04:45stopped,
00:04:45its mate
00:04:46is in
00:04:47mid-stroke
00:04:48and near
00:04:50its maximum
00:04:50speed.
00:04:52And
00:04:52therefore,
00:04:53the pistons
00:04:54are exchanging
00:04:55energy with
00:04:56each other
00:04:56and not
00:04:58with the
00:04:58crankshaft,
00:04:59so there's
00:04:59no yanking
00:05:01going to the
00:05:02back tire.
00:05:03and
00:05:04Mr.
00:05:04Furusawa
00:05:05said,
00:05:05I don't
00:05:06know which
00:05:06it is,
00:05:07whether it
00:05:08actually
00:05:08physically
00:05:09interferes
00:05:10with the
00:05:10rear tire
00:05:11or whether
00:05:12it makes
00:05:13it hard
00:05:13for the
00:05:14rider
00:05:14to sense
00:05:15how much
00:05:16grip there
00:05:16is.
00:05:18Well,
00:05:19they fixed
00:05:20that
00:05:20at the
00:05:22end of
00:05:222003
00:05:23and in
00:05:242004,
00:05:25Valentino
00:05:26Rossi
00:05:26on a
00:05:2790-degree
00:05:28inline
00:05:29bike
00:05:29won
00:05:30the
00:05:30world
00:05:30championship.
00:05:32The
00:05:32cross-plane.
00:05:33Yes,
00:05:33the so-called
00:05:34cross-plane
00:05:35crankshaft.
00:05:37So,
00:05:37that was a
00:05:39definite
00:05:39handicap of
00:05:40the inline
00:05:41four versus
00:05:42the V4
00:05:43and they
00:05:43fixed that.
00:05:45So,
00:05:46now the
00:05:47question is,
00:05:49we'd really
00:05:52like it if
00:05:53a Yamaha
00:05:54representative
00:05:54would say,
00:05:56may I have
00:05:57the microphone
00:05:57please?
00:05:58and said,
00:05:59here is
00:06:00where our
00:06:01problem lies
00:06:02and we're
00:06:03fixing it.
00:06:05See you
00:06:06next week.
00:06:08But
00:06:09evidently,
00:06:10it isn't
00:06:10that simple.
00:06:12And
00:06:13while
00:06:15Corderaro
00:06:16himself,
00:06:17after riding
00:06:17the V4
00:06:18at the
00:06:19Monday test
00:06:20after
00:06:21Misano
00:06:21last weekend,
00:06:23said,
00:06:24it has the
00:06:25same problems
00:06:26as the
00:06:26inline.
00:06:26now Yamaha's
00:06:30PR voice
00:06:32is saying,
00:06:33all the
00:06:33riders agree
00:06:34that it's
00:06:36a step
00:06:36forward.
00:06:40So,
00:06:41we know
00:06:43that the
00:06:44nail that
00:06:45sticks up
00:06:46gets hammered
00:06:47down.
00:06:48So,
00:06:49we hope
00:06:50that Mr.
00:06:51Corderaro
00:06:52will tread
00:06:54carefully.
00:06:55But
00:06:55this kind
00:06:58of thing
00:06:59happens
00:06:59constantly
00:07:00in racing.
00:07:01Back in
00:07:02the 1930s,
00:07:03Mercedes
00:07:03and
00:07:04Auto
00:07:05Union
00:07:05were
00:07:06tremendous
00:07:07rivals.
00:07:07and
00:07:09they
00:07:10were
00:07:10spending
00:07:10money
00:07:11hand
00:07:11over
00:07:11fist.
00:07:13And
00:07:13each
00:07:13one
00:07:14wondered,
00:07:14hmm,
00:07:15does
00:07:16the
00:07:16other
00:07:16guy
00:07:17have
00:07:17an
00:07:17advantage
00:07:18with
00:07:18the
00:07:18type
00:07:18of
00:07:18engine
00:07:19they're
00:07:19building?
00:07:20We'd
00:07:20better
00:07:20build
00:07:20one
00:07:21and
00:07:21test
00:07:21it.
00:07:23And
00:07:23out of
00:07:23the
00:07:23other
00:07:23side
00:07:24of
00:07:24their
00:07:24mouth
00:07:24they're
00:07:24saying,
00:07:25and
00:07:25the
00:07:25test
00:07:25had
00:07:26better
00:07:26come
00:07:26out
00:07:26saying
00:07:27that
00:07:27we've
00:07:27done
00:07:28it
00:07:28right
00:07:28all
00:07:28along,
00:07:29which
00:07:29means
00:07:30the
00:07:30test
00:07:30has
00:07:30no
00:07:31value.
00:07:32Honda
00:07:33and
00:07:33Yamaha
00:07:34were
00:07:34locked
00:07:34in
00:07:35battle
00:07:35in
00:07:36500
00:07:37GP.
00:07:39Yamaha
00:07:39were
00:07:39using
00:07:40two
00:07:41contra
00:07:42rotating
00:07:42crankshafts
00:07:44in
00:07:44their
00:07:44V4.
00:07:45Honda
00:07:45was
00:07:46using
00:07:46a
00:07:46single
00:07:47crankshaft.
00:07:48Each
00:07:49company
00:07:49built
00:07:50this is
00:07:50according
00:07:51to,
00:07:52you know,
00:07:52I don't
00:07:52know
00:07:53this,
00:07:54but
00:07:54people
00:07:55have
00:07:55said
00:07:55people
00:07:56people,
00:07:57yes,
00:07:58we call
00:07:58them
00:07:58pundits,
00:07:59man
00:07:59in the
00:08:00street.
00:08:01They
00:08:02have
00:08:02said
00:08:02that
00:08:03each
00:08:03company
00:08:03built
00:08:04an
00:08:05example
00:08:05of
00:08:06the
00:08:06other
00:08:06company's

00:08:08make
00:08:08sure
00:08:09that
00:08:09they
00:08:10hadn't
00:08:10overlooked
00:08:11something
00:08:11of
00:08:13value.
00:08:14So
00:08:14we
00:08:16don't
00:08:16know
00:08:16that
00:08:17there's
00:08:17a
00:08:17problem
00:08:18with
00:08:18the
00:08:18inline
00:08:19four
00:08:19other
00:08:20than
00:08:20that
00:08:21there
00:08:22has
00:08:22been

00:08:23dreadful
00:08:23sameness
00:08:24over
00:08:24the
00:08:24past
00:08:25four
00:08:27years,
00:08:29three
00:08:29or four
00:08:29years,
00:08:30that
00:08:31the
00:08:31Yamaha
00:08:32is
00:08:32lacking
00:08:32in
00:08:33rear
00:08:33grip.
00:08:34It
00:08:34goes
00:08:35well
00:08:35when
00:08:35there's
00:08:36good
00:08:37grip
00:08:37on
00:08:37the
00:08:37track.
00:08:41But
00:08:42quarter
00:08:44row
00:08:44just
00:08:45looks
00:08:46like,
00:08:47you know,
00:08:48I don't
00:08:48know how
00:08:48many years
00:08:49I have
00:08:49left to
00:08:50serve,
00:08:50but I
00:08:51sort of
00:08:51resigned
00:08:52myself to
00:08:53this.
00:08:53Pay
00:08:54is good.
00:08:54when I
00:08:58get out
00:08:59of this
00:08:59place,
00:09:00I could
00:09:00buy
00:09:00myself
00:09:01a
00:09:01motorcycle
00:09:01and have
00:09:02some
00:09:02fun.
00:09:03So
00:09:04this is
00:09:06a
00:09:07problem
00:09:08for us.
00:09:08So I
00:09:09thought to
00:09:10myself,
00:09:10well,
00:09:11why don't
00:09:11I go
00:09:12through
00:09:13some of
00:09:15the
00:09:15differences
00:09:16between
00:09:16the
00:09:17inline
00:09:18and the
00:09:19V4?
00:09:21Not
00:09:21because I
00:09:22think we're
00:09:22going to
00:09:23find the
00:09:23answer
00:09:23there,
00:09:24because
00:09:24plenty of
00:09:26people have
00:09:26talked about
00:09:27it before
00:09:27now,
00:09:28but just
00:09:29for review.
00:09:32And
00:09:32the first
00:09:34thing is
00:09:34weight
00:09:35placement.
00:09:36And in
00:09:36the early
00:09:37days of
00:09:37the inline,
00:09:39Yamaha had
00:09:40the cylinders
00:09:41and exhaust
00:09:42pipes right
00:09:42up against
00:09:43the front
00:09:43tire.
00:09:44And even
00:09:44before that,
00:09:46in 500
00:09:46GP,
00:09:47people were
00:09:48trying to
00:09:49put the
00:09:49engine as
00:09:50far forward
00:09:51as they
00:09:51could to
00:09:52the point
00:09:52of cutting
00:09:53slots in
00:09:53the radiator
00:09:54for the
00:09:55engine parts
00:09:57on one
00:09:57side or
00:09:58for the
00:09:58tire on
00:09:59the other
00:09:59side.
00:10:02Now
00:10:02people are
00:10:03saying,
00:10:03well,
00:10:04geez,
00:10:05you know,
00:10:05the V4
00:10:07has more
00:10:07weight to
00:10:08the rear
00:10:08because like
00:10:09the rear
00:10:10cylinders are
00:10:10above the
00:10:11gearbox,
00:10:12whereas on
00:10:12the Yamaha,
00:10:14all the
00:10:14cylinders are
00:10:15as far
00:10:16forward as
00:10:16they can
00:10:17go.
00:10:20But why
00:10:22do they
00:10:22put the
00:10:22cylinders,
00:10:23why do
00:10:23they put
00:10:23mass forward?
00:10:24So that the
00:10:25front wheel
00:10:26doesn't come
00:10:27up as
00:10:27easily and
00:10:28the rider
00:10:28can therefore
00:10:29accelerate
00:10:30harder.
00:10:31We've all
00:10:32seen riders
00:10:32pull themselves
00:10:33forward on
00:10:34the bike to
00:10:36accelerate because
00:10:38they need to
00:10:39put as much
00:10:40weight on the
00:10:41front wheel as
00:10:41possible so that
00:10:42it doesn't
00:10:43lift.
00:10:44and oh,
00:10:45where did
00:10:45my steering
00:10:46go?
00:10:48So there's
00:10:50a long
00:10:50history of
00:10:51forward weight
00:10:51placement.
00:10:54And this
00:10:56was why,
00:10:58well,
00:10:59with the
00:11:00V4,
00:11:00it's not
00:11:04possible to
00:11:05have the
00:11:05weight of
00:11:06those rear
00:11:07facing cylinders
00:11:08as far
00:11:09forward as
00:11:10the front
00:11:11row.
00:11:12So this
00:11:14does something
00:11:15for the
00:11:16front rear
00:11:16weight distribution
00:11:17or have they
00:11:18moved other
00:11:18components to
00:11:20compensate for
00:11:20it?
00:11:21You can
00:11:22talk about
00:11:22centralizing of
00:11:23the mass.
00:11:24I mean,
00:11:24you're going
00:11:24to put
00:11:24those.
00:11:25Oh,
00:11:25that's another
00:11:26one that
00:11:26the Honda
00:11:28people have
00:11:29talked about
00:11:29this since
00:11:31the days of
00:11:31Red Page
00:11:32so long
00:11:33ago,
00:11:35that the
00:11:37Yamaha engine
00:11:38is more like
00:11:39a 24-pound
00:11:40ladder and
00:11:41the V4 is
00:11:42more like a
00:11:4324-pound
00:11:43cannonball.
00:11:45If you're
00:11:45going to
00:11:46suddenly reverse
00:11:47direction,
00:11:48the cannonball
00:11:49is not going
00:11:49to oppose you
00:11:50very strongly
00:11:51because its
00:11:52mass is
00:11:52located close
00:11:54to its
00:11:54center.
00:11:54So you
00:11:54just pivot
00:11:56around.
00:11:57Whereas the
00:11:5728 or 10
00:11:59foot long
00:12:0024-pound
00:12:01ladder,
00:12:01it's some
00:12:04effort required.
00:12:06Well,
00:12:07is it a
00:12:08significant
00:12:08effort?
00:12:11Who can
00:12:12say?
00:12:14Honda,
00:12:14Yamaha,
00:12:15they could
00:12:15say.
00:12:16They've
00:12:16got...
00:12:16Yes, and
00:12:17Eric Buell
00:12:18could say.
00:12:19Eric Buell,
00:12:20yes,
00:12:20indeed.
00:12:21Well, he
00:12:22was a huge
00:12:22proponent of
00:12:23that weight
00:12:24on the
00:12:24front wheel
00:12:25and talking
00:12:25to engineers
00:12:26who had
00:12:27been at
00:12:27Buell.
00:12:28That was
00:12:28their big...
00:12:31Getting that
00:12:32weight on the
00:12:33front wheel,
00:12:33they say,
00:12:34is what allowed
00:12:35them to use
00:12:35that extreme
00:12:36front-end
00:12:36geometry
00:12:37without having
00:12:38head-shaking
00:12:39death machines.
00:12:40And stability,
00:12:41sure, because
00:12:42the stability
00:12:43of a motorcycle
00:12:43depends on the
00:12:44damping that
00:12:45comes from
00:12:45its rubbery
00:12:46tires.
00:12:46tires.
00:12:48And if
00:12:48you take
00:12:49the weight
00:12:49off of
00:12:50one of
00:12:50those tires,
00:12:51the tire
00:12:52may become
00:12:53wayward.
00:12:54I'm always
00:12:55thinking about
00:12:55this when I'm
00:12:56pushing a
00:12:56shopping cart
00:12:57because if the
00:12:58cart is
00:12:58twisted slightly
00:12:59and one of
00:13:00the front
00:13:00wheels is a
00:13:01little light,
00:13:03it just
00:13:03starts to
00:13:04and give
00:13:06you a
00:13:06headache.
00:13:06But I
00:13:11want to
00:13:11call
00:13:11attention
00:13:12to
00:13:12something
00:13:12else.
00:13:13And that
00:13:14is that
00:13:15in the
00:13:15departed
00:13:16era of
00:13:17500cc
00:13:18Grand Prix,
00:13:19when the
00:13:20rider tucked
00:13:21in, his
00:13:23chin went
00:13:23into a
00:13:24depression in
00:13:24the fuel
00:13:25tank and
00:13:26his eyes,
00:13:27if he looked
00:13:27down, were
00:13:28looking at
00:13:29the fuel
00:13:29tank.
00:13:31Today, they've
00:13:32moved the
00:13:32rider so far
00:13:33forward that
00:13:34the tank has
00:13:35had to become
00:13:35a mushroom
00:13:36they've pushed
00:13:37it from the
00:13:38rear and
00:13:38it's
00:13:39bulged out
00:13:40at the
00:13:40sides.
00:13:42And now
00:13:43if the
00:13:43rider tucks
00:13:44in, he's
00:13:45looking at
00:13:46the upper
00:13:47crown of
00:13:47the front
00:13:48fork.
00:13:49So they've
00:13:50pushed the
00:13:51rider far
00:13:51forward.
00:13:52So what I
00:13:53would say
00:13:54is if the
00:13:55V4 solves
00:13:57the problem
00:13:57of moving
00:13:58weight to
00:13:58the rear,
00:13:59it ought to
00:14:00be pretty
00:14:00easy to
00:14:01correct.
00:14:04So why
00:14:04have them?
00:14:05Remind me
00:14:05of those
00:14:05evolution of
00:14:06you're
00:14:06thinking back
00:14:07to, you
00:14:09know, RC
00:14:09166 and
00:14:11the Grand
00:14:12Prix bikes
00:14:12of the
00:14:121960s, it
00:14:13strikes me
00:14:15that if we
00:14:15did silhouettes
00:14:16we could
00:14:16have an
00:14:18evolution of
00:14:18man type
00:14:20of progression
00:14:22of the
00:14:23ass, starting
00:14:24at the back
00:14:24wheel and
00:14:24slowly moving
00:14:25forward.
00:14:26Absolutely.
00:14:27It's one of
00:14:28the most
00:14:28striking
00:14:28differences
00:14:29between then
00:14:30and now
00:14:31is the
00:14:31rider placement.
00:14:33Quite low
00:14:34motorcycles before
00:14:35two and
00:14:35now you're
00:14:36really sticking
00:14:38things on
00:14:39their nose and
00:14:39getting the
00:14:39seat quite
00:14:40high.
00:14:41I mean, of
00:14:41course, we
00:14:42are dealing
00:14:42with variable
00:14:43ride height
00:14:44as well at
00:14:45this point,
00:14:45which is...
00:14:47That's a big
00:14:47complication.
00:14:48The complexity
00:14:49of the system
00:14:50now is
00:14:53mind-boggling
00:14:54because we're
00:14:55talking about
00:14:55very simple
00:14:56things, not
00:14:56very simple
00:14:57things, but
00:14:57we're talking
00:14:58about, oh,
00:14:58wait, we're
00:14:59going to put
00:14:59all the weight
00:15:00on the front
00:15:00of the bike
00:15:00by using
00:15:01an inline
00:15:01four, and
00:15:02maybe we'll
00:15:03move some
00:15:03of it toward
00:15:04the center
00:15:04of mass by
00:15:05putting the
00:15:05cylinders in
00:15:06the back,
00:15:07not talking
00:15:09about every
00:15:10other possible
00:15:11influence on
00:15:12all these
00:15:12other things.
00:15:13And as you
00:15:14said, moving
00:15:14other components
00:15:15and a lot
00:15:18of bikes,
00:15:19they're sticking
00:15:19the batteries
00:15:20up on top
00:15:20of the air,
00:15:21like street
00:15:21bikes, sticking
00:15:22the batteries
00:15:22up on top
00:15:23of the air
00:15:23box and
00:15:24the electronics
00:15:25and putting
00:15:26all those
00:15:26things up
00:15:27there rather
00:15:27than back
00:15:28under the
00:15:29seat.
00:15:29Now, there's
00:15:30a problem
00:15:32here because
00:15:33the riders
00:15:33have been
00:15:34saying for
00:15:35several years,
00:15:36all of them,
00:15:37not just
00:15:37Fabio or
00:15:38Cordero,
00:15:39they've all
00:15:40been saying
00:15:40that they
00:15:41would like
00:15:42more weight
00:15:43on the
00:15:43back tire
00:15:44or more
00:15:44grip from
00:15:46the back
00:15:47tire.
00:15:48Some of
00:15:48the riders
00:15:49have said,
00:15:49Ducati has
00:15:50enough, but
00:15:51I don't.
00:15:53And we
00:15:56don't know
00:15:56that this is
00:15:57a problem,
00:15:58but people
00:15:58are talking
00:15:59about it.
00:16:00Yeah.
00:16:00Yeah.
00:16:01They just
00:16:01have more.
00:16:02They have
00:16:03more.
00:16:04When you're
00:16:05braking straight
00:16:06up for a
00:16:06corner, the
00:16:09maximum braking
00:16:10occurs when
00:16:11the rear tire
00:16:12barely leaves
00:16:13the ground.
00:16:15You can't
00:16:15brake any
00:16:16harder than
00:16:16that because
00:16:18the back end
00:16:19will come
00:16:19around or
00:16:20it will go
00:16:22ass over
00:16:23appetite.
00:16:24so people
00:16:27talk about
00:16:28needing to
00:16:29use the
00:16:30rear brake
00:16:31more.
00:16:32Well, they're
00:16:32obviously not
00:16:33using it
00:16:34more during
00:16:34straight line
00:16:35braking before
00:16:36a corner
00:16:36entry because
00:16:38if they tried
00:16:39to use the
00:16:39rear brake
00:16:40while there's
00:16:40no weight
00:16:41on the rear
00:16:41wheel,
00:16:42nothing will
00:16:44happen in
00:16:44the way of
00:16:45braking.
00:16:47So another
00:16:48extreme that
00:16:49you could say
00:16:50is, well,
00:16:50what if they
00:16:50lower the
00:16:51motorcycle so
00:16:52much that
00:16:52when the
00:16:53rider brakes
00:16:53hard enough
00:16:54to lift the
00:16:55rear wheel
00:16:55that it
00:16:57pushes the
00:16:58front tire,
00:16:58threatens to
00:16:59lock.
00:17:00Then you
00:17:01could use
00:17:01the rear
00:17:02brake because
00:17:03there's some
00:17:04weight on
00:17:04there.
00:17:06But then
00:17:06you hear also
00:17:07riders are
00:17:09using the
00:17:09rear brake
00:17:1070% of the
00:17:11time going
00:17:12through a
00:17:12corner.
00:17:13And I can
00:17:14understand that
00:17:14on several
00:17:16bases.
00:17:17It's a good
00:17:18way to adjust
00:17:19chassis attitude
00:17:21because the
00:17:22rear brake
00:17:23caliper is
00:17:23attached to
00:17:24the swing
00:17:24arm.
00:17:24So if you
00:17:25brake, it
00:17:26tends to
00:17:26compress the
00:17:27rear suspension.
00:17:28Oh, that
00:17:29was a famous
00:17:29Freddie Spencer
00:17:30quote from
00:17:31back in the
00:17:31day.
00:17:31There were
00:17:32two instances
00:17:33when I worked
00:17:34at Cycle News.
00:17:35I read an
00:17:35old race report
00:17:36about Freddie
00:17:37Spencer and
00:17:38Henny Ray
00:17:39Abens asked
00:17:39him about the
00:17:40rear brake.
00:17:41And at the
00:17:42time, Freddie
00:17:43probably fibbing,
00:17:45rear brake?
00:17:45Huh, I never
00:17:46touch it.
00:17:47Yeah.
00:17:48When in fact,
00:17:49he did touch it
00:17:50and he was a
00:17:50big proponent
00:17:51of it all the
00:17:51way through his
00:17:52school, you
00:17:53know, when he
00:17:53was doing the
00:17:53Freddie Spencer
00:17:54riding school,
00:17:55high performance,
00:17:56Freddie Spencer
00:17:57high performance
00:17:57riding school.
00:17:59Yeah.
00:17:59And he was a
00:18:00huge proponent
00:18:01of as you're
00:18:02entering the
00:18:03corner, rear
00:18:04brake a little
00:18:04bit first to
00:18:05squat the bike,
00:18:06just as you say,
00:18:07and then
00:18:07swift but smooth
00:18:10application of the
00:18:11front brake to
00:18:11compress everything
00:18:12and get the
00:18:13contact patch out
00:18:14nice and wide.
00:18:15And to go
00:18:16farther back in
00:18:17history, perhaps
00:18:18not as far as the
00:18:19great pyramids at
00:18:20Giza, but
00:18:21approaching that
00:18:23in Mike
00:18:24Halewood's
00:18:24little book on
00:18:25riding, he
00:18:26says, apply the
00:18:28rear brake an
00:18:30instant before the
00:18:30front because it
00:18:31steadies you up.
00:18:33So, that's not
00:18:37exactly a physical
00:18:38explanation, but
00:18:39if...
00:18:40Hey, all you
00:18:40thirsty listeners
00:18:42out there, I
00:18:43will say on my
00:18:44Vela set, when
00:18:46you are hammering
00:18:47that thing on a
00:18:48back road, which
00:18:49I've done many,
00:18:49many times, the
00:18:51chassis is so
00:18:52flexible and the
00:18:53fork is so
00:18:53flexible, using the
00:18:54rear brake keeps
00:18:55the thing from
00:18:56piling up on the
00:18:57front, keeps it
00:18:58from flexing and
00:18:59wobbling and
00:19:01weaving.
00:19:01It kind of
00:19:02makes it handle
00:19:02a lot better.
00:19:03Oh, your
00:19:03drag steer gets
00:19:04out of shape and
00:19:05you pop the
00:19:05chute.
00:19:06That's right.
00:19:07Then it
00:19:07straightens right
00:19:08up.
00:19:09Helps a lot.
00:19:10It really
00:19:10does.
00:19:12So, another
00:19:16one that everyone
00:19:17holds forth about
00:19:18is engine width.
00:19:20Oh, the V4 is so
00:19:21narrow.
00:19:23It's got to have
00:19:24an aerodynamic
00:19:25advantage.
00:19:25Well, where would
00:19:26we see this?
00:19:27At the end of the
00:19:28straightaway.
00:19:28Well, the
00:19:30Yamaha is down
00:19:31on power, but
00:19:33it's always been
00:19:34down on power.
00:19:35It was down on
00:19:36power when Wayne
00:19:38Rainey was winning
00:19:39races on the
00:19:40500.
00:19:42Because, as
00:19:43Jerry Burgess
00:19:45used to say,
00:19:48there's one
00:19:49straightaway and
00:19:50there are 12 or
00:19:5114 corners.
00:19:53where would you
00:19:54like to put your
00:19:55advantage?
00:19:57And their
00:19:58bike was
00:19:59optimized for
00:20:00acceleration, for
00:20:01usable torque, for
00:20:03accelerating off of
00:20:04corners, and they
00:20:04didn't bother about
00:20:06top-end power, and
00:20:08it's been that way
00:20:08for years.
00:20:10It's been an
00:20:10expected outcome.
00:20:12I'm out reading
00:20:13all the time,
00:20:14thinking about
00:20:15things, and this
00:20:16is a related
00:20:17automotive story,
00:20:18Doug Thorley, of
00:20:20the famed Doug
00:20:21Thorley Headers
00:20:21company, was
00:20:24way back working
00:20:25with Carroll
00:20:25Shelby on the
00:20:26GT350, and
00:20:27that's where the
00:20:27Tri-Y, the
00:20:292 into 2
00:20:31into 1, on
00:20:33a V8, it's
00:20:34on either side.
00:20:35One is a
00:20:351-3-2-4, and
00:20:37the other one
00:20:38is a one, I
00:20:41forget the
00:20:42groupings, but
00:20:42the groupings are
00:20:43different because
00:20:43of the V8
00:20:44firing order.
00:20:45But Doug
00:20:45Thorley and
00:20:45Carroll Shelby,
00:20:46Carroll wanted
00:20:46more mid-range,
00:20:48he wanted more
00:20:48pull off of
00:20:49corners, and
00:20:50supposedly that's
00:20:51the origins of
00:20:53the Tri-Y on
00:20:54the V8 in
00:20:54that era.
00:20:56Yeah.
00:20:57And that's what
00:20:58we've seen on
00:20:59street bikes, too,
00:20:59we've seen the
00:21:00groupings of
00:21:02cylinders, and
00:21:03emphasizing mid-range,
00:21:04which is great on
00:21:05the street, but
00:21:05also as Kevin and
00:21:06everyone is pointing
00:21:07out, if you can
00:21:08accelerate harder
00:21:09off of 17
00:21:10corners and gain a
00:21:11fraction on
00:21:127.
00:21:13Each time.
00:21:13Each time.
00:21:14Well, gosh, that's
00:21:15better than, I got
00:21:17five more miles an
00:21:18hour on the
00:21:18street.
00:21:19Yeah.
00:21:19Oh, God, I got
00:21:19a brake.
00:21:20Brake, brake.
00:21:23Sure.
00:21:24So, is the
00:21:28engine wider than
00:21:29the rider?
00:21:31No.
00:21:32The inline four is
00:21:33not wider than the
00:21:34rider.
00:21:35The V4 is not
00:21:37wider than the
00:21:37rider.
00:21:38So, I don't
00:21:40think that really
00:21:41has much in it.
00:21:43except if you
00:21:45look at it as
00:21:46the, there's a
00:21:47difference between
00:21:48external aerodynamics
00:21:49and internal.
00:21:52Internal
00:21:52aerodynamics, you're
00:21:53taking in a huge
00:21:54volume of air
00:21:55through the curved
00:21:57radiator up front.
00:21:59And where does
00:22:00it go?
00:22:01Well, it blows on
00:22:03the engine's header
00:22:04pipes.
00:22:05And then it
00:22:06makes its way
00:22:08like the merry
00:22:10little breezes through
00:22:11the woods.
00:22:12It makes its
00:22:13way in and
00:22:14out and among
00:22:15all of this
00:22:16stuff that's
00:22:17packed into
00:22:17motorcycles.
00:22:18They're like a
00:22:19submarine.
00:22:20Submarines barely
00:22:21have room for
00:22:21the people.
00:22:22They have to
00:22:23sleep with
00:22:23torpedoes next
00:22:25to them.
00:22:26Well, that
00:22:29air leaks out.
00:22:31Last year, the
00:22:32Aprilia riders
00:22:33were saying they
00:22:35couldn't finish
00:22:36races in any
00:22:38kind of state
00:22:39of physical
00:22:40well-being because
00:22:41they were being
00:22:42baked by the
00:22:43engine heat.
00:22:45So engine heat
00:22:46is trying to get
00:22:47out anywhere that
00:22:48it can.
00:22:50You'll also
00:22:51notice that
00:22:52Kenny's 500
00:22:54cc two-stroke
00:22:55triple had two
00:22:56versions, one
00:22:58with two
00:22:58cylinders up and
00:22:59one cylinder down
00:23:00and the later
00:23:01one, I think,
00:23:03had one
00:23:03cylinder up and
00:23:04two cylinders
00:23:05down.
00:23:06Well, why
00:23:07would they do
00:23:08that?
00:23:09One possible
00:23:09reason would
00:23:10be to duct
00:23:11the outflow
00:23:13from the
00:23:14radiator around
00:23:15the engine to
00:23:16the low
00:23:16pressure at
00:23:17the rear of
00:23:18the motorcycle.
00:23:21It's hard to
00:23:22see where
00:23:23they're getting
00:23:24that air out.
00:23:25They're still
00:23:26putting it out
00:23:26through cheek
00:23:28outlets in the
00:23:29fairing, but
00:23:31supposedly Ducati
00:23:33in studying
00:23:34the super
00:23:36mono found
00:23:38that cheek
00:23:39outlets for
00:23:40radiator air
00:23:41are not a
00:23:42good solution
00:23:42with respect
00:23:44to drag.
00:23:46And one
00:23:47of Kenny's
00:23:49three-cylinder
00:23:50500s, the
00:23:52over-built
00:23:53Triumph, and
00:23:55John Britton's
00:23:58wonderful
00:23:59thousand cc
00:24:00what-if
00:24:03motorcycle, all
00:24:04had ducted
00:24:05radiators.
00:24:06In some
00:24:07cases, the
00:24:08radiator was
00:24:08horizontal
00:24:09underneath the
00:24:10seat, and
00:24:11ducts came
00:24:12from the
00:24:12front to
00:24:14the radiators,
00:24:15but nobody
00:24:16is running
00:24:16such a thing
00:24:17now.
00:24:19So,
00:24:21mood.
00:24:23So, that
00:24:24bothers me.
00:24:27Another one
00:24:27that people
00:24:28like to talk
00:24:28about is
00:24:29crankshaft
00:24:29bearing loss.
00:24:30The inline
00:24:31four has, of
00:24:32course, four
00:24:33crankpins
00:24:34disposed, in
00:24:35the case of
00:24:36the Yamaha, at
00:24:3690 degrees
00:24:37all the way
00:24:38along.
00:24:39The dual
00:24:40plane
00:24:40crankshaft.
00:24:42And it
00:24:43has five
00:24:44main bearings,
00:24:45one at
00:24:45either end,
00:24:46and three
00:24:47between adjacent
00:24:48cylinders.
00:24:50Well, that's
00:24:51a real
00:24:53difference right
00:24:54there, isn't
00:24:54it?
00:24:54Look, there's
00:24:55five main
00:24:55bearings, and
00:24:56over here,
00:24:56this V4 only
00:24:57has two
00:24:58crankpins and
00:24:59three main
00:25:00bearings.
00:25:02Aha, we
00:25:02found it.
00:25:04Oh, wait a
00:25:05minute now.
00:25:07The total
00:25:08load on
00:25:09bearings is
00:25:10the same
00:25:11between the
00:25:12two motorcycles.
00:25:13Pistons are
00:25:13yanking up and
00:25:14down.
00:25:15So, and
00:25:18here's another
00:25:18proposal killer,
00:25:21a favorite of
00:25:22mine.
00:25:22let's imagine
00:25:24that 25%
00:25:26of the
00:25:26energy of
00:25:27the combustion
00:25:29gas beating
00:25:29on the
00:25:30pistons goes
00:25:31for friction.
00:25:32Some of it
00:25:33goes for
00:25:34pushing the
00:25:34pistons down
00:25:35the cylinder
00:25:36while the
00:25:37rings are
00:25:38loaded outward
00:25:40against the
00:25:40cylinder wall,
00:25:41and the
00:25:42few oil
00:25:44molecules that
00:25:45are between
00:25:45the rings and
00:25:46the cylinder
00:25:47wall are
00:25:47kind of being
00:25:48rolled up into
00:25:49little balls,
00:25:50and they're
00:25:51objecting.
00:25:52This is
00:25:53called sliding
00:25:54friction.
00:25:57Some of it
00:25:58goes to the
00:26:00bearings, some
00:26:00of it goes to
00:26:01the accessories,
00:26:02the water
00:26:02pump, the
00:26:03electricity
00:26:04station.
00:26:06So, what
00:26:07do they do?
00:26:09At the
00:26:09factory, they
00:26:11have a
00:26:11motoring
00:26:12dyno.
00:26:13It has an
00:26:13electric motor
00:26:14that will spin
00:26:15the engine that
00:26:16you want to
00:26:17test.
00:26:17You put the
00:26:19engine on
00:26:19there, and
00:26:21you spin it
00:26:22with an
00:26:23electric motor,
00:26:24and you
00:26:24measure the
00:26:25torque required
00:26:26to spin it
00:26:27at various
00:26:28RPM, and
00:26:28you record
00:26:31the data.
00:26:32Next, you
00:26:33test a
00:26:34series of
00:26:35partial builds.
00:26:37You remove
00:26:38various things
00:26:39from the
00:26:39engine, the
00:26:40accessories,
00:26:42the
00:26:42camshafts,
00:26:45the
00:26:46rings,
00:26:47and
00:26:49leave the
00:26:49pistons.
00:26:50And what
00:26:51do you
00:26:51find?
00:26:52You find
00:26:52that the
00:26:53pistons and
00:26:53rings are
00:26:54at least
00:26:56half of
00:26:57total engine
00:26:58friction,
00:26:59which is
00:27:00something like
00:27:0025% of
00:27:03gross power.
00:27:05I didn't
00:27:05say net,
00:27:06I said
00:27:06gross.
00:27:08So,
00:27:10the
00:27:10crankshaft
00:27:11bearings seem
00:27:12to be good
00:27:13for about
00:27:1410% of
00:27:1625%,
00:27:17which is
00:27:182.5%
00:27:19of engine
00:27:22power.
00:27:23So,
00:27:24well,
00:27:24that's
00:27:24something.
00:27:26We should
00:27:27give that
00:27:27some attention.
00:27:28But,
00:27:29having five
00:27:30main bearings
00:27:31instead of
00:27:32three,
00:27:33with both
00:27:34sets of
00:27:34bearings carrying
00:27:35the same
00:27:35load,
00:27:36seems to me
00:27:37like this
00:27:38is moot.
00:27:39this is
00:27:39not a
00:27:40big
00:27:40distinction.
00:27:46Okay,
00:27:47we have
00:27:48another
00:27:50biggie
00:27:50here,
00:27:50which is
00:27:51what I
00:27:52learned
00:27:52from
00:27:54Mr.
00:27:57Ishikawa
00:27:58when I
00:27:58visited
00:27:59Honda.
00:28:00We're
00:28:00standing in
00:28:01the lobby,
00:28:02which is
00:28:02about as
00:28:02far as
00:28:03you can
00:28:03get at
00:28:04HRC.
00:28:05We were
00:28:05shown to
00:28:06a conference
00:28:08room,
00:28:09been told
00:28:09to put
00:28:09our
00:28:09coats
00:28:10there.
00:28:12But,
00:28:12in the
00:28:13lobby,
00:28:13they had
00:28:13the new
00:28:14Fireblade
00:28:16and Mr.
00:28:19Ishikawa
00:28:20said,
00:28:22I am an
00:28:23inline guy.
00:28:24I really
00:28:25like inline
00:28:26engines.
00:28:27He is the
00:28:28LPL on
00:28:29the 2020
00:28:30Fireblade.
00:28:32He said,
00:28:33the big
00:28:34difference
00:28:34between an
00:28:35inline and
00:28:36the V4
00:28:36is
00:28:37crankshaft
00:28:38stability.
00:28:39when an
00:28:42inline
00:28:421000cc
00:28:43engine
00:28:44gets up
00:28:44around
00:28:4516,000
00:28:46RPM,
00:28:48that's
00:28:48about it
00:28:49for smooth
00:28:50rotation of
00:28:50the crankshaft.
00:28:52Rev it up
00:28:52higher and
00:28:53you begin to
00:28:53get torsional
00:28:55vibrations.
00:28:57And those
00:28:58torsional
00:28:59vibrations
00:28:59affect valve
00:29:01timing.
00:29:01Because what
00:29:02that means
00:29:02is that
00:29:03instead of
00:29:04rotating
00:29:04smoothly,
00:29:05like a
00:29:07giant fly
00:29:08wheel,
00:29:09the crankshaft
00:29:10has RPM
00:29:11flutter.
00:29:12So,
00:29:13in calculating
00:29:15our valve
00:29:16float
00:29:16threshold,
00:29:18do we
00:29:18use,
00:29:19here's the
00:29:20flutter,
00:29:21do we use
00:29:21the maximum
00:29:22value,
00:29:23the minimum
00:29:23value,
00:29:24the average
00:29:25value of
00:29:25the RPM?
00:29:26and of
00:29:29course,
00:29:30I've told
00:29:31this tale
00:29:31before,
00:29:32but I'm
00:29:32going to
00:29:32tell it
00:29:33again and
00:29:33you can
00:29:34just yawn
00:29:35and show
00:29:36your displeasure
00:29:37by various
00:29:38means.
00:29:39But,
00:29:41where am I
00:29:43going with
00:29:44this?
00:29:44We were
00:29:47in RPM
00:29:48flutter.
00:29:49Yeah,
00:29:49the flutter.
00:29:50Honda
00:29:51have
00:29:52published
00:29:52some
00:29:53reports
00:29:54on their
00:29:55past
00:29:55experiences
00:29:56in Formula
00:29:57One.
00:29:58I think
00:29:58this is
00:29:59wonderfully
00:29:59generous
00:30:00of them
00:30:00and it's
00:30:01a warning
00:30:01to the
00:30:02other
00:30:02Formula
00:30:02One
00:30:03constructors.
00:30:05Look at
00:30:05all the
00:30:06incredible
00:30:07lengths we
00:30:07go to.
00:30:08Give up
00:30:08now.
00:30:09There's
00:30:09still time.
00:30:12So,
00:30:13the example
00:30:14given was
00:30:15they said
00:30:16we develop
00:30:16this valve
00:30:17train.
00:30:18Maybe it
00:30:19has pneumatic
00:30:20springs,
00:30:20who knows.
00:30:21But at
00:30:21any rate,
00:30:22they develop
00:30:23the profile
00:30:24that they
00:30:24want to
00:30:24give the
00:30:26intake
00:30:27airflow
00:30:27that the
00:30:28engine
00:30:29requires.
00:30:30And they
00:30:31find the
00:30:32valve float
00:30:34threshold.
00:30:35How do
00:30:35they find
00:30:36it?
00:30:36They use
00:30:37an
00:30:39interferometric
00:30:40device to
00:30:42measure the
00:30:42valve
00:30:43position to
00:30:44one
00:30:46wavelength of
00:30:46light.
00:30:49And they
00:30:51find that
00:30:52the valve
00:30:54float
00:30:54threshold is
00:30:55when the
00:30:57valve motion
00:30:58no longer
00:30:58corresponds to
00:30:59the cam
00:31:00profile.
00:31:02So,
00:31:03let's say
00:31:03that occurs
00:31:04at x
00:31:05RPM.
00:31:06Now,
00:31:07they take
00:31:07that lovely,
00:31:09beautifully
00:31:09developed
00:31:10valve train
00:31:11and put it
00:31:11on the
00:31:12engine that
00:31:12it's intended
00:31:13for.
00:31:14And they
00:31:15started him
00:31:17up and
00:31:18pretty soon
00:31:19it's warm
00:31:20and we're
00:31:21ready to
00:31:22run.
00:31:24Where's the
00:31:25valve throat?
00:31:26Valve float
00:31:27threshold.
00:31:27x minus
00:31:301,500 RPM.
00:31:36Now,
00:31:37this
00:31:38is
00:31:41strongly
00:31:42different from
00:31:43our intuitive
00:31:45idea of the
00:31:45crack shaft.
00:31:46You've got this
00:31:47thing in your
00:31:47hands of
00:31:48steel.
00:31:48It's strong.
00:31:50Actually,
00:31:51it's jello.
00:31:51you give it
00:31:56a tap with
00:31:56a soft
00:31:57hammer and
00:31:58it goes
00:31:58bong so
00:32:00you know
00:32:00it vibrates.
00:32:02You wind
00:32:03one end up
00:32:04and let it
00:32:04go and it
00:32:05vibrates at a
00:32:06different
00:32:07frequency.
00:32:09And because
00:32:10the pistons
00:32:11are accelerating
00:32:13the crankshaft
00:32:13when they fire
00:32:14and the
00:32:14crankshaft is
00:32:15coasting down
00:32:16between firing
00:32:17impulses,
00:32:18there is a
00:32:18flutter from
00:32:20combustion
00:32:20pressure.
00:32:23Well,
00:32:25the higher
00:32:27you rev
00:32:28an engine,
00:32:30the greater
00:32:30the chance
00:32:31that the
00:32:32torsional
00:32:33frequency
00:32:34of the
00:32:35engine will
00:32:36be excited
00:32:36by something
00:32:37that's happening
00:32:38such as the
00:32:38sequence of
00:32:39combustion pulses
00:32:40or the
00:32:41resistance of
00:32:42the camshafts
00:32:43coming through
00:32:43the gear
00:32:44drive.
00:32:45Because the
00:32:46camshaft is
00:32:46trying to
00:32:48accelerate a
00:32:49valve at
00:32:49what,
00:32:503,000,
00:32:514,000 times
00:32:52gravity?
00:32:54That's a
00:32:54pulse of
00:32:55torque.
00:32:56That's a
00:32:56bunch of
00:32:57torque.
00:32:58And then
00:32:59the next
00:32:59minute,
00:33:00another valve
00:33:01is closing
00:33:01and it's
00:33:02giving back
00:33:02that energy.
00:33:03The spring
00:33:04is expanding.
00:33:05That power
00:33:06is going
00:33:06into the
00:33:07camshaft.
00:33:08So the
00:33:08camshaft
00:33:09itself is
00:33:10subject to
00:33:11torsional
00:33:12windup.
00:33:13This is one
00:33:14of the reasons
00:33:14why the
00:33:15recent builds
00:33:16of giant
00:33:17V8s way
00:33:18out beyond
00:33:18600
00:33:19cubic
00:33:19inches.
00:33:20They're
00:33:20putting
00:33:21these huge
00:33:21cams in
00:33:22because they
00:33:25need a
00:33:25stiffer cam
00:33:26to keep
00:33:26it out
00:33:27of torsional
00:33:27vibration.
00:33:29Well,
00:33:30that 1500
00:33:31RPM difference
00:33:33between the
00:33:34ideal valve
00:33:35float threshold
00:33:37and the
00:33:38actual one
00:33:38is a
00:33:40serious
00:33:40business.
00:33:40So in
00:33:44Formula 1
00:33:44crankshafts
00:33:46have all
00:33:46these
00:33:47dampers,
00:33:48different
00:33:49kinds of
00:33:50dampers on
00:33:50the
00:33:50crankshaft
00:33:51and on
00:33:52the
00:33:52camshaft,
00:33:52sometimes
00:33:53on both
00:33:53ends.
00:33:54One of
00:33:55the systems
00:33:55that Honda
00:33:56tested had
00:33:57two cam
00:33:57drives,
00:33:58one on
00:33:58each end
00:33:59of the
00:34:01camshaft.
00:34:02So this
00:34:05is serious
00:34:06business.
00:34:07Okay,
00:34:08the V4
00:34:08has little
00:34:09short
00:34:09camshafts
00:34:10and it
00:34:10has a
00:34:11little
00:34:11short
00:34:11crankshaft.
00:34:12It is
00:34:13stable,
00:34:14relatively
00:34:14speaking,
00:34:15said Mr.
00:34:16Ishikawa,
00:34:17up to
00:34:1718,000
00:34:18before it
00:34:21starts to
00:34:22need help
00:34:23in the
00:34:23form of
00:34:24some sort
00:34:24of dampers.
00:34:25Yeah.
00:34:26And this
00:34:27is not
00:34:28some kind
00:34:29of ionospheric
00:34:30weirdness
00:34:31that only
00:34:32happens at
00:34:33HRC
00:34:34because
00:34:35those of
00:34:36you with
00:34:36experience
00:34:37of RC-30
00:34:38Honda
00:34:38will remember
00:34:40some of
00:34:41them came
00:34:41with camshafts
00:34:42with fly
00:34:43wheels on
00:34:44them.
00:34:45Makes sense.
00:34:46So this
00:34:47is a serious
00:34:48problem with
00:34:49engines.
00:34:50Well,
00:34:51it's everywhere,
00:34:51Kevin,
00:34:52because I was
00:34:52underneath my
00:34:53Ford F-250
00:34:54taking the
00:34:55engine out
00:34:55some months
00:34:56ago and
00:34:57there were a
00:34:58few things
00:34:58that needed
00:34:59some impact
00:34:59and I
00:35:00invested my
00:35:02half-inch
00:35:02snap-on
00:35:03air
00:35:03ratchet
00:35:04impact gun
00:35:06gave up.
00:35:07I needed
00:35:08to take
00:35:08it apart
00:35:09and fix
00:35:09it.
00:35:09So I
00:35:09did the
00:35:10expedient
00:35:11thing and
00:35:11I bought
00:35:11a new
00:35:12Makita
00:35:12with the
00:35:121100 pound
00:35:15feet of
00:35:15what they
00:35:16say nut
00:35:16busting
00:35:17torque for
00:35:18loosening
00:35:19something up.
00:35:19So I had
00:35:20some very
00:35:20tight things
00:35:22underneath,
00:35:22exhaust things
00:35:23and I
00:35:23needed to
00:35:24hammer them
00:35:24off.
00:35:25But I
00:35:26couldn't get
00:35:26the gun
00:35:27up there.
00:35:27So the
00:35:30one I
00:35:30could get
00:35:30to,
00:35:31socket,
00:35:32gun,
00:35:33off it
00:35:34came.
00:35:35The one
00:35:35I had
00:35:35to get
00:35:36upped
00:35:36into,
00:35:37I used
00:35:37a long
00:35:37extension.
00:35:40You know
00:35:40what that
00:35:40is?
00:35:41That's a
00:35:41torsional
00:35:41spring.
00:35:42Yes,
00:35:42sir.
00:35:43Did not
00:35:44want to
00:35:44come off.
00:35:45Had to
00:35:46find other
00:35:46strategies.
00:35:47And it's
00:35:48exactly what's
00:35:48happening with
00:35:49the crank.
00:35:49You think
00:35:50about any,
00:35:50you know,
00:35:50just stretch
00:35:51the length,
00:35:52short stubby
00:35:52screwdriver,
00:35:53as close as
00:35:54you can get
00:35:55to the work,
00:35:56your force
00:35:56goes into
00:35:56the nut,
00:35:57you get far
00:35:58away through
00:35:58a long
00:35:59bar,
00:35:59you just
00:36:01sit there
00:36:01gung,
00:36:02gung,
00:36:02gung,
00:36:02gung,
00:36:02gung,
00:36:03gung,
00:36:03gung,
00:36:03gung,
00:36:03gung,
00:36:03gung,
00:36:04you could
00:36:04do that
00:36:05forever and
00:36:05it isn't
00:36:06going to
00:36:06move because
00:36:06it's
00:36:07sucking it
00:36:07up,
00:36:08vibrating away.
00:36:10It's not
00:36:10transmitting the
00:36:11impacts very
00:36:14well through
00:36:15that spring.
00:36:16Yeah,
00:36:16it's softening
00:36:17it up.
00:36:19So I
00:36:20take this
00:36:21valve timing
00:36:21thing quite
00:36:22seriously,
00:36:23but these
00:36:24companies,
00:36:26they read
00:36:29the literature,
00:36:30they are
00:36:31involved with
00:36:32Formula One,
00:36:33they know
00:36:34all this
00:36:34stuff and
00:36:36they have
00:36:36the equipment
00:36:37with which
00:36:37to test
00:36:38and discover
00:36:39what is
00:36:40happening.
00:36:41So there
00:36:44used to
00:36:44be,
00:36:45MIT had a
00:36:46special
00:36:47tarsio graph
00:36:48that was
00:36:49attached to
00:36:50the crankshafts
00:36:51of big
00:36:51radials and
00:36:53they found
00:36:53out that
00:36:54these massive
00:36:56three main
00:36:58bearing,
00:36:58crankshafts
00:37:00were winding
00:37:01up more
00:37:02than half
00:37:02a degree.
00:37:05Now you
00:37:05imagine
00:37:06fastening
00:37:09one end
00:37:09of it to
00:37:10a reliable
00:37:11steel structure
00:37:12and putting
00:37:13a bar on
00:37:13the other
00:37:14end and
00:37:14dangling from
00:37:15it and
00:37:16looking at
00:37:17the deflection.
00:37:19Do we have
00:37:19a half a
00:37:20degree yet?
00:37:21No,
00:37:21no.
00:37:22Get some
00:37:22more fellows
00:37:23on this
00:37:23bar.
00:37:24But what
00:37:26does happen
00:37:27is that
00:37:27when you
00:37:27get up
00:37:28to the
00:37:29speed
00:37:29where
00:37:30the
00:37:30torsional
00:37:32frequency
00:37:32of the
00:37:33crankshaft
00:37:34is being
00:37:36excited by
00:37:37rapid events
00:37:38in the
00:37:38engine,
00:37:40then it's
00:37:40like pushing
00:37:41a small
00:37:41child on
00:37:42the swing.
00:37:43You keep
00:37:44pushing in
00:37:45synchrony with
00:37:46the swing
00:37:46and pretty
00:37:47soon the
00:37:47chains are
00:37:48going slack
00:37:49at the
00:37:50height of
00:37:50the swing.
00:37:51and you're
00:37:52thinking this
00:37:53is crazy.
00:37:54Good thing
00:37:55my wife
00:37:55isn't here
00:37:56because I'd
00:37:57hear about
00:37:57this.
00:38:00So this
00:38:02is some
00:38:03serious
00:38:04stuff.
00:38:06Making
00:38:06the valves
00:38:07do your
00:38:07bidding.
00:38:09But I
00:38:09think these
00:38:09are competent
00:38:10companies.
00:38:11I don't
00:38:11think that
00:38:12this is a
00:38:14problem for
00:38:14the people
00:38:15in this
00:38:16series.
00:38:18Okay,
00:38:19well,
00:38:19another one.
00:38:20How about
00:38:20crankshaft
00:38:22windage?
00:38:26Oil is
00:38:27flying out
00:38:27of the
00:38:28main and
00:38:29connecting rod
00:38:30bearings,
00:38:30so there's
00:38:31oil in
00:38:31there.
00:38:32Where does
00:38:32it go?
00:38:34Well,
00:38:34ideally it
00:38:35flies out,
00:38:36hits the
00:38:36walls of
00:38:37the crank
00:38:38case,
00:38:39and
00:38:39trickles
00:38:42down to
00:38:43where the
00:38:43scavenge
00:38:43pump is
00:38:44located.
00:38:46But
00:38:47that's a
00:38:49minor problem.
00:38:50the real
00:38:51problem is
00:38:52pumping air
00:38:53on an
00:38:54inline
00:38:55engine.
00:38:56And you
00:38:57may remember
00:38:57this from,
00:38:58I don't know,
00:38:5915, 20
00:38:59years ago,
00:39:00when the
00:39:01manufacturers
00:39:02discovered
00:39:03that it
00:39:04took power
00:39:05for the
00:39:07descending
00:39:08piston to
00:39:09push the
00:39:09air around
00:39:10the main
00:39:12bearing to
00:39:13be able to
00:39:13follow the
00:39:14adjacent piston,
00:39:15which is
00:39:16rising.
00:39:16and then
00:39:17when it
00:39:17reverses,
00:39:18the air
00:39:19goes back
00:39:19and forth
00:39:21and back
00:39:22and forth
00:39:22to the tune
00:39:23of four or
00:39:24five horsepower
00:39:24they were
00:39:25picking up
00:39:26in production
00:39:27inline
00:39:28force by
00:39:29making
00:39:30big,
00:39:31smooth-edged
00:39:32holes
00:39:33between...
00:39:34Oh, yeah,
00:39:34the ports.
00:39:35Yeah, the ports.
00:39:37So that is
00:39:38the real meaning
00:39:39of crankcase
00:39:40windage.
00:39:40And it
00:39:44used to be
00:39:44that at
00:39:45the end
00:39:45of each
00:39:46year Yamaha
00:39:47would publish
00:39:48a technical
00:39:49report on
00:39:50their year
00:39:51in Grand
00:39:51Prix racing.
00:39:52They don't
00:39:52do it
00:39:52anymore,
00:39:53I believe,
00:39:54because it
00:39:56doesn't do
00:39:57to tell
00:39:57other people
00:39:58what you're
00:39:59up to.
00:40:01So if
00:40:03the Russians
00:40:03had been
00:40:04ready for
00:40:04the drone
00:40:05attacks,
00:40:06but you
00:40:08learn by
00:40:08experience.
00:40:09what Yamaha
00:40:13did was
00:40:13they put
00:40:14a vacuum
00:40:14pump on
00:40:15the crankcase
00:40:16and they
00:40:18pumped the
00:40:18crankcase
00:40:18down so
00:40:19there was
00:40:20no wind
00:40:20to have
00:40:21windage.
00:40:22There was
00:40:22nothing to
00:40:23transfer from
00:40:24one crank
00:40:25chamber to
00:40:26the next.
00:40:28And when
00:40:29I went to
00:40:30Gainesville,
00:40:32or no,
00:40:32Charlotte for
00:40:33NHRA a
00:40:35while ago,
00:40:37they showed
00:40:38me their
00:40:38crankcase.
00:40:39It's
00:40:40electric and
00:40:41it makes
00:40:42quite a
00:40:43loud noise.
00:40:44You know
00:40:45how a
00:40:46diaphragm
00:40:47pump for
00:40:48painting or
00:40:49whatever is
00:40:50noisy.
00:40:52So they
00:40:53flick this
00:40:53thing on,
00:40:54makes a
00:40:55loud noise,
00:40:56pumps out
00:40:57all the air
00:40:57from the
00:40:57crankcase,
00:40:58no more
00:40:58windage.
00:40:59I'm going
00:40:59suction side
00:41:00of a
00:41:00leaf blower
00:41:01on my
00:41:01Velocet.
00:41:02so what
00:41:07does Honda
00:41:07do?
00:41:09I suspect
00:41:10that what
00:41:10they do
00:41:11is what
00:41:12you hear
00:41:12about
00:41:13Formula
00:41:13One,
00:41:13which is
00:41:14you divide
00:41:14the engine
00:41:16down the
00:41:17center and
00:41:18have two
00:41:19sealed
00:41:19crankpin
00:41:20chambers
00:41:21with a
00:41:22main bearing
00:41:23between them.
00:41:23each side
00:41:26has its
00:41:26own oil
00:41:27scavenge
00:41:27pump.
00:41:29What happens
00:41:30is the two
00:41:30pistons are
00:41:31moving this
00:41:32way and
00:41:34the air is
00:41:38moving but
00:41:39it has
00:41:40nothing in
00:41:41its way.
00:41:41so it's
00:41:43largely
00:41:45loss free
00:41:46and if
00:41:49you have
00:41:49a narrower
00:41:49V angle
00:41:50than 90
00:41:51you're
00:41:53compressing
00:41:53and expanding
00:41:54it.
00:41:55Well,
00:41:55it's like
00:41:55compressing
00:41:56and expanding
00:41:57a spring.
00:41:59You get
00:42:00the energy,
00:42:00you put in
00:42:01the energy
00:42:01and you get
00:42:02back 98%.
00:42:03So these
00:42:06companies have
00:42:07worked on
00:42:08crankcase
00:42:09windage.
00:42:09I heard
00:42:12I was
00:42:13recently at
00:42:13a car race
00:42:14in the pit
00:42:14working with
00:42:16a friend
00:42:16on an
00:42:17800 horsepower
00:42:17tube frame
00:42:19American race
00:42:21car Mustang
00:42:21and was
00:42:23talking about
00:42:23the engine
00:42:24and it's
00:42:24800 horse
00:42:265.8 liter
00:42:27it's got a
00:42:28big four
00:42:29barrel carb
00:42:30on it
00:42:30just a lawn
00:42:31sprinkler up
00:42:32there doing
00:42:32its job
00:42:33and the
00:42:36mains are
00:42:37basically
00:42:38capped and
00:42:39sealed
00:42:39with its
00:42:40own
00:42:41like
00:42:42tray
00:42:44it's got
00:42:44its own
00:42:44pump
00:42:45so the
00:42:45main oil
00:42:46never sees
00:42:47the inside
00:42:48of the
00:42:48crankcase
00:42:50it's just
00:42:50sucked
00:42:50right out
00:42:51of the
00:42:51mains
00:42:51and back
00:42:52into the
00:42:52oil supply
00:42:53so it
00:42:55bolts
00:42:56right up
00:42:56so I
00:42:57thought that
00:42:57was an
00:42:58interesting
00:42:58case
00:42:59for
00:43:00windage
00:43:00yeah
00:43:01well that
00:43:02was
00:43:02that's
00:43:03the story
00:43:03about
00:43:04junior
00:43:04johnson
00:43:05and
00:43:06zero
00:43:08w10
00:43:09oil
00:43:09because
00:43:11he saw
00:43:13that
00:43:14there was
00:43:15you know
00:43:15everybody
00:43:16in the
00:43:16engine
00:43:16business
00:43:17has
00:43:17put a
00:43:18lucite
00:43:18window
00:43:19and some
00:43:20powerful
00:43:20lights
00:43:21and looked
00:43:21at what's
00:43:22going on
00:43:22in the
00:43:22crankcase
00:43:23just as
00:43:23you did
00:43:24with your
00:43:24gearbox
00:43:24and they
00:43:26have found
00:43:27that it
00:43:27is a
00:43:28terrible
00:43:28storm
00:43:29in the
00:43:30north
00:43:30atlantic
00:43:31that is
00:43:32threatening
00:43:32to turn
00:43:32your boat
00:43:33upside down
00:43:33and
00:43:35junior
00:43:37thought
00:43:38I gotta
00:43:39reduce the
00:43:40volume of
00:43:40oil present
00:43:41in the
00:43:42engine
00:43:42in any
00:43:42given
00:43:43instant
00:43:43and his
00:43:44first thought
00:43:44was
00:43:45smaller
00:43:46clearances
00:43:47less
00:43:48viscous
00:43:48oil
00:43:49and
00:43:51the
00:43:51lubrication
00:43:52guy said
00:43:53well you
00:43:53go down
00:43:53in viscosity
00:43:54pretty soon
00:43:55the
00:43:55asperities
00:43:57asperities
00:43:57I was
00:43:58waiting
00:43:58for it
00:43:59yes
00:43:59it's been
00:44:01so long
00:44:01yes
00:44:02oh my
00:44:03old friend
00:44:04the
00:44:05asperities
00:44:06on the
00:44:07crank
00:44:07journals
00:44:07are sticking
00:44:09up through
00:44:09the oil
00:44:10film
00:44:10and gouging
00:44:11the bearing
00:44:12super finish
00:44:13let's go
00:44:14you can't
00:44:14do that
00:44:15well he
00:44:16thought what
00:44:16if we make
00:44:17the crankshaft
00:44:17journal smoother
00:44:18and an
00:44:21old fellow
00:44:21that he
00:44:22must have
00:44:23encountered
00:44:23said well
00:44:24you know
00:44:24what we
00:44:24did
00:44:25during
00:44:25the war
00:44:25we
00:44:26carceler
00:44:27developed a
00:44:28super finish
00:44:29process
00:44:29uses
00:44:30laps
00:44:31and
00:44:32they
00:44:33they're
00:44:34supported
00:44:34on cool
00:44:35oil
00:44:35and they
00:44:36don't touch
00:44:37the journal
00:44:37until the
00:44:38oil temperature
00:44:39comes up
00:44:40and gradually
00:44:40the laps
00:44:41move closer
00:44:42and closer
00:44:42to the
00:44:43crankpin
00:44:43until finally
00:44:44they're just
00:44:45taking the
00:44:45tops of the
00:44:46asperities
00:44:47off
00:44:47and they
00:44:49let it
00:44:49move down
00:44:50until
00:44:50the cycle
00:44:52is finished
00:44:52and then
00:44:53they have
00:44:53this
00:44:53journal
00:44:54which is
00:44:54not
00:44:55micro
00:44:55polished
00:44:56micro
00:44:56polish
00:44:57is what
00:44:57you get
00:44:57at the
00:44:58shoe shine
00:44:58stand
00:44:59what you
00:45:01get is a
00:45:02true cylinder
00:45:02that's what
00:45:04you need
00:45:04in the way
00:45:05of a
00:45:06crankshaft
00:45:06journal
00:45:06so
00:45:07that
00:45:10was
00:45:12and I
00:45:12believe
00:45:12Honda
00:45:13almost
00:45:13immediately
00:45:14applied that
00:45:15to
00:45:15Goldwing
00:45:16it has
00:45:17it has
00:45:18a super
00:45:18finished
00:45:19crankshaft
00:45:19from
00:45:21years ago
00:45:22so this
00:45:23is all
00:45:24old hat
00:45:24isn't it
00:45:26all though
00:45:27well it
00:45:28is yes
00:45:28because
00:45:29we don't
00:45:30know
00:45:30and we
00:45:31don't know
00:45:31any flies
00:45:32on the
00:45:32wall
00:45:32what's
00:45:33going on
00:45:33at HRC
00:45:34or whatever
00:45:35Yamaha
00:45:35call their
00:45:36think tank
00:45:38not deep
00:45:39inside
00:45:40don't you
00:45:40just want
00:45:40the
00:45:41you just
00:45:42want to
00:45:42go to
00:45:43Ducati
00:45:43and have
00:45:43them take
00:45:44the whole
00:45:44thing apart
00:45:45right in
00:45:45front of
00:45:46you
00:45:46start asking
00:45:48questions
00:45:49wouldn't
00:45:49that be
00:45:49great
00:45:50it would
00:45:50be cool
00:45:51so
00:45:52this
00:45:54leaves us
00:45:54with this
00:45:55with this
00:45:55oh by the
00:45:56one thing
00:45:57I left
00:45:57out
00:45:57let's
00:45:58imagine
00:45:59that each
00:45:59crankshaft
00:46:00main bearing
00:46:01contributes an
00:46:02equal amount
00:46:03of friction
00:46:04torque
00:46:04so
00:46:05the Yamaha
00:46:06has five
00:46:07the Honda
00:46:09has three
00:46:10the other
00:46:10V4s all
00:46:11have three
00:46:12well
00:46:14the Yamaha
00:46:15has only
00:46:16one cam
00:46:16drive
00:46:17and two
00:46:18cams
00:46:19and the
00:46:20others
00:46:20my goodness
00:46:21they have
00:46:22two
00:46:23cam drives
00:46:24two sets
00:46:25of gears
00:46:25oh
00:46:27think of
00:46:28the friction
00:46:28think of
00:46:30the
00:46:30think of
00:46:31the lost
00:46:31motion
00:46:32the timing
00:46:33inaccuracies
00:46:34oh
00:46:35where's
00:46:36my
00:46:36where's
00:46:36my
00:46:36motion
00:46:37I need
00:46:38three
00:46:39so
00:46:41again
00:46:43to me
00:46:43it seems
00:46:44moot
00:46:45so I get
00:46:47down to the
00:46:47end of
00:46:48this list
00:46:49I wrote
00:46:50this all
00:46:50up
00:46:50as a
00:46:51sort of
00:46:52guideline
00:46:52to this
00:46:53conversation
00:46:54and at
00:46:56the end
00:46:56the idea
00:46:59that I
00:46:59thought of
00:46:59was
00:47:00every now
00:47:01and then
00:47:01it's a
00:47:02good idea
00:47:02to start
00:47:03over
00:47:03because you
00:47:04might think
00:47:04of something
00:47:05new
00:47:05and
00:47:07switching
00:47:08to a
00:47:08V4
00:47:09is a
00:47:09way
00:47:10to do
00:47:10that
00:47:11but
00:47:12motorcycle
00:47:14races
00:47:14are seldom
00:47:15won by
00:47:16engine
00:47:17power
00:47:17so all
00:47:18this focusing
00:47:19on what
00:47:20the engine
00:47:20can produce
00:47:22in the way
00:47:23of power
00:47:24or power
00:47:24band
00:47:24that's
00:47:26one set
00:47:26of questions
00:47:27but the
00:47:27other set
00:47:27of questions
00:47:28is
00:47:28why
00:47:30couldn't
00:47:30they get
00:47:31the Yamaha
00:47:32chassis
00:47:32to handle
00:47:33and why
00:47:34is
00:47:34Quartarero
00:47:35saying
00:47:36now
00:47:37that the
00:47:37new bike
00:47:38is no
00:47:39improvement
00:47:39on the
00:47:40inline
00:47:40well
00:47:41and an
00:47:42interesting
00:47:42observation
00:47:43that I
00:47:43saw
00:47:44wandering
00:47:44around
00:47:45the
00:47:45great
00:47:45interwebs
00:47:46Matt
00:47:47Oxley
00:47:48you know
00:47:49a long
00:47:49time
00:47:50writer
00:47:51and technically
00:47:51oriented
00:47:52guy
00:47:52you can
00:47:53find him
00:47:53just search
00:47:54for Matt
00:47:55Oxley
00:47:55and you
00:47:55can hear
00:47:56about all
00:47:57his stories
00:47:57of MotoGP
00:47:58he's been
00:47:58a long
00:47:59time observer
00:47:59and he
00:48:00gets up
00:48:00in there
00:48:01he said
00:48:02he'd never
00:48:04seen a
00:48:05pivot area
00:48:05swing arm
00:48:06pivot area
00:48:06on the
00:48:07V4
00:48:07he'd never
00:48:08seen a
00:48:08pivot area
00:48:09as flexible
00:48:10as the
00:48:11new Yamaha
00:48:12V4's
00:48:13is
00:48:13he said
00:48:14that the
00:48:14pivot area
00:48:15is almost
00:48:16as thin
00:48:16as the
00:48:17Ducati
00:48:18Desmosidichi
00:48:19engine
00:48:19hangars
00:48:20yeah
00:48:20and
00:48:21and they're
00:48:23still
00:48:23complaining
00:48:23about
00:48:24rear grip
00:48:24so
00:48:25and what
00:48:26he's
00:48:26talking
00:48:26what
00:48:26they're
00:48:27going
00:48:27for
00:48:27is
00:48:28that
00:48:28sideways
00:48:28suspension
00:48:29that
00:48:29Kevin
00:48:29has
00:48:30talked
00:48:30about
00:48:30for
00:48:30decades
00:48:31now
00:48:32is that
00:48:32getting the
00:48:33motorcycle
00:48:34leaned over
00:48:34and you know
00:48:36you can't compress
00:48:37the suspension
00:48:37at a 60 degree
00:48:39angle as well
00:48:40as you can
00:48:40when it's vertical
00:48:41and you need
00:48:42something that
00:48:43has a little
00:48:43give to allow
00:48:44the side
00:48:45of the tire
00:48:46the side
00:48:46of the tire
00:48:47has a little
00:48:47give
00:48:47but not a lot
00:48:49so you need
00:48:50something that
00:48:50can do that
00:48:51in a semi
00:48:52controlled fashion
00:48:53to give
00:48:54to follow
00:48:54contours
00:48:55and increase
00:48:56your
00:48:56side grip
00:48:58because we
00:49:00know
00:49:00that when
00:49:01a motorcycle
00:49:02is made
00:49:02with an
00:49:03extremely
00:49:03stiff
00:49:04steering head
00:49:05that it
00:49:08is likely
00:49:08to have
00:49:10little
00:49:10rider
00:49:11feel
00:49:11and
00:49:13when
00:49:14talking
00:49:16about
00:49:16Ducati's
00:49:17carbon fiber
00:49:19combined
00:49:20airbox
00:49:21and
00:49:21Vincent
00:49:22style
00:49:23upper
00:49:24chassis
00:49:25Casey
00:49:30Stoner
00:49:30said
00:49:31on that
00:49:33one
00:49:33he said
00:49:35you're
00:49:37in the
00:49:37corner
00:49:37and
00:49:39analysis
00:49:40afterward
00:49:41reveals
00:49:42that
00:49:43all
00:49:44measured
00:49:44variables
00:49:46are the
00:49:46same as
00:49:47they were
00:49:47for the
00:49:48previous
00:49:48three
00:49:48laps

00:49:56down
00:49:57you go
00:49:58and
00:50:00of course
00:50:00the most
00:50:01ignominious
00:50:01is the
00:50:02road grader
00:50:02orientation
00:50:03where you're
00:50:04sliding

00:50:36at the
00:50:36chassis
00:50:37and you
00:50:37can see
00:50:37why
00:50:38because
00:50:38the
00:50:38chassis
00:50:39beams
00:50:39come up

00:51:01big
00:51:01V-twin
00:51:02had so
00:51:03little
00:51:04mid-range

00:54:40looks
00:54:40hopeless
00:54:40on the
00:54:42outside
00:54:42but
00:54:43I
00:54:43don't
00:54:43doubt
00:54:44that
00:54:44Yamaha
00:54:45will
00:54:45get
00:54:45there
00:54:46this
00:54:47is
00:54:47especially
00:54:47troubling
00:54:48to me
00:54:48because
00:54:49I
00:54:50a lot
00:54:51of the
00:54:51things
00:54:51that I
00:54:52learned
00:54:52about
00:54:52racing
00:54:53I
00:54:53learned
00:54:53from
00:54:54running
00:54:55Yamaha
00:54:55production
00:54:56racers
00:54:56starting
00:54:57with the
00:54:58TD1s
00:54:59and then
00:54:59on
00:54:59into
00:55:00the
00:55:00TZ250
00:55:02and then
00:55:02finally
00:55:03TZ750
00:55:04take a
00:55:04drink
00:55:04folks
00:55:05yep
00:55:06and
00:55:07so I
00:55:10have a
00:55:10kind of
00:55:12underlying
00:55:12respect
00:55:14for their
00:55:16history
00:55:17but when
00:55:18you see
00:55:19the
00:55:19rider
00:55:20saying the
00:55:20same
00:55:21thing
00:55:21year
00:55:21after
00:55:21year
00:55:22when
00:55:24asked
00:55:24how are
00:55:25the
00:55:25preseason
00:55:25tests
00:55:26going
00:55:26at
00:55:27Sepang
00:55:27and
00:55:28he
00:55:29looks
00:55:29like
00:55:29well
00:55:32it
00:55:34hasn't
00:55:35changed
00:55:36much
00:55:36and
00:55:39the
00:55:39higher
00:55:41ups
00:55:41are
00:55:41going
00:55:41that
00:55:43little
00:55:43bastard
00:55:43I'll
00:55:45get even
00:55:45with him
00:55:45and
00:55:47it's
00:55:49it's
00:55:50inexplicable
00:55:51but there
00:55:54is this
00:55:54that I
00:55:56have
00:55:56noticed
00:55:56and that
00:55:57is
00:55:57that
00:55:58manufacturers
00:55:59have a
00:56:01history of
00:56:02going into
00:56:02a slump
00:56:03and staying
00:56:04there as
00:56:05if they
00:56:06liked it
00:56:06now
00:56:08Honda
00:56:10did that
00:56:11in the
00:56:12early years
00:56:13of the
00:56:13century
00:56:14in 2003
00:56:17Ducati
00:56:17came with
00:56:18all this
00:56:19horsepower
00:56:19and
00:56:20Honda
00:56:22were terribly
00:56:23offended
00:56:23because
00:56:24there was
00:56:25a gentleman's
00:56:26agreement
00:56:26that
00:56:27nothing
00:56:28above
00:56:28superbike
00:56:29level
00:56:29would be
00:56:29used
00:56:30in
00:56:30MotoGP
00:56:31and
00:56:32Ducati
00:56:33just came
00:56:33with
00:56:34mad
00:56:35power
00:56:35and
00:56:36Loris
00:56:37Caporasi
00:56:37and
00:56:38later
00:56:39with
00:56:41others
00:56:42and they
00:56:43so
00:56:44Honda
00:56:45just
00:56:45horsepower
00:56:46you want
00:56:47horsepower
00:56:47they went
00:56:48to the
00:56:48back of
00:56:49the room
00:56:49where these
00:56:49big
00:56:50pails
00:56:50of
00:56:50horsepower
00:56:51they're
00:56:52all
00:56:52marked
00:56:52triple
00:56:53X
00:56:53quad
00:56:54X
00:56:55and they
00:56:55dumped
00:56:56horsepower
00:56:56into the
00:56:57thing
00:56:57until it
00:56:57didn't
00:56:57handle
00:56:58very
00:56:59well
00:57:00and
00:57:02you could
00:57:02see this
00:57:03the riders
00:57:03struggling
00:57:04with these
00:57:05things
00:57:05they had
00:57:05a lot
00:57:05of
00:57:05power
00:57:06but
00:57:07nothing
00:57:08you could
00:57:09use
00:57:09so
00:57:09Yamaha
00:57:10who were
00:57:12still
00:57:13sticking
00:57:13to their
00:57:14get it
00:57:16off the
00:57:17corners
00:57:17and think
00:57:17about the
00:57:18straightaway
00:57:18if there's
00:57:19time
00:57:19methodology
00:57:23won a
00:57:24bunch of
00:57:24championships
00:57:25and it
00:57:26wasn't
00:57:27until
00:57:28mid-season
00:57:302010
00:57:31and the
00:57:32Hondas
00:57:32began to
00:57:33look
00:57:33well
00:57:34Pedrosa
00:57:35began to
00:57:35look almost
00:57:36graceful
00:57:37like he
00:57:37was not
00:57:38riding an
00:57:39electric
00:57:39bar
00:57:39bull
00:57:40and I
00:57:42looked at
00:57:43that and
00:57:43I thought
00:57:44they're
00:57:45coming back
00:57:46they'll be
00:57:46here
00:57:47well what
00:57:48happened
00:57:49next year
00:57:49Stoner went
00:57:50to Honda
00:57:51he won
00:57:5210 races
00:57:52and the
00:57:53championship
00:57:53just as he'd
00:57:54done at
00:57:55Ducati in
00:57:562007
00:57:56so
00:57:57the engine
00:58:01influences
00:58:02handling
00:58:02the rider
00:58:03influences
00:58:03handling
00:58:04the chassis
00:58:05the tires
00:58:06get a
00:58:08handle on
00:58:09it
00:58:09I don't
00:58:10think it's
00:58:10going to
00:58:10be easy
00:58:11because
00:58:12unless we
00:58:14say
00:58:14and this
00:58:15is tempting
00:58:15that for
00:58:17three years
00:58:18they've come
00:58:19to the
00:58:19pre-season
00:58:19tests
00:58:20with
00:58:20I don't
00:58:22see anything
00:58:22new
00:58:23unless that
00:58:27means
00:58:27well we
00:58:28we had
00:58:28to cut
00:58:29back
00:58:29spinning
00:58:29so
00:58:32then you
00:58:33look at
00:58:33the end
00:58:33of the
00:58:34handlebars
00:58:35to see
00:58:35if the
00:58:36handlebar
00:58:36grip is
00:58:37sort of
00:58:37crushed
00:58:38from being
00:58:38leaned
00:58:39against the
00:58:39wall in
00:58:40an unused
00:58:41corridor
00:58:42put some
00:58:43new grips
00:58:44on that
00:58:44that's the
00:58:452025
00:58:45now
00:58:46I don't
00:58:49I don't
00:58:50think this
00:58:50is the
00:58:51case
00:58:51but it
00:58:52is something
00:58:52that people
00:58:53think of
00:58:53if there's
00:58:55little change
00:58:56so Honda
00:58:58had a
00:58:59period of
00:59:00being in
00:59:01the wilderness
00:59:02Ducati
00:59:03had a period
00:59:04of being in
00:59:04the wilderness
00:59:04after 2007
00:59:06each year
00:59:08Stoner won
00:59:09fewer races
00:59:10now you can
00:59:11say oh well
00:59:12he had an
00:59:13illness and
00:59:14he you know
00:59:15this and that
00:59:16okay but
00:59:17they won
00:59:18fewer races
00:59:18every year
00:59:19and
00:59:21they seemed
00:59:24to be
00:59:24satisfied to
00:59:25finish
00:59:25sixth
00:59:26seventh
00:59:27or eighth
00:59:28it went
00:59:29on for
00:59:29years and
00:59:30they were
00:59:30thinking
00:59:30there has
00:59:32to be some
00:59:33kind of
00:59:34institutional
00:59:35policy going
00:59:36on here
00:59:37we do not
00:59:38mess with the
00:59:38swing arm
00:59:39pivot because
00:59:40it's where
00:59:40the maestro
00:59:41put it
00:59:41or something
00:59:43like that
00:59:43and remember
00:59:45yes
00:59:46yeah when
00:59:47did Ducati
00:59:48pull
00:59:48D'Alinea
00:59:50in
00:59:50well
00:59:51because
00:59:54that
