		Comments:	Very few motorcycles can claim the throne of
				the Horsepower King.  The V-Max is one of them.
				Not exactly a cruiser or a standard, and
				certainly not a sportbike or a touring machine,
				the V-Max occupies a niche of its own, one in
				which brute acceleration is the only grail worth
				chasing.  The V-Max get its power from an 1198cc
				V-Four Engine derived from the Venture Royale's
				1294cc motor.  The Max-motor is fed by
				carburation linked in what Yamaha calls its
				V-Boost system,  which increases full throttle
	DoD Law #1	-----------------------------------------^^^^^^^^^^^^^
				intake flow at high rpm.  Overall, the V-Max is
				practical and comfortable; but anyone who tells
				you that's why he wants one is either kidding
				or flat-out lying.
		----------------------------------------------------------------

	Carburated, 4 x Mikuni 1" 3/8 mounted on the VBoost assembly.  Its
	a 2way intake tunnel with a trap between each pair of carburators.
	When a certain RPM is reach it open.  That's what give that humongus
	"launch" when you hit 6,500-7,000 RPM and just shift from two to
	three...  Else you got a very good distribution of HP's all over the RPM
	line...

	lifters like in CAM LIFTERS (See CAGE.1 under HAS BEEN ENGINE.2):
	Nop 2 Over "the" Head Cam (Its a V4 mounted flat: I mean that its
	mounted like \/ with a intake directly from the top.  From what my
	doctor says its the best setup for a bike engine but its less effective
	in the space zone (that's why a VMax look like somekind of bulldog).

*** HINT from my bike doctor: to get a bit more out of some 4 in-lines motor
*** modify the frame so the carburators are less horizontal: mostly the
*** carburators vs heads are at 65 degrees.  He said that he've try with a
*** 600 super-sport and from 65 to 55 degrees he gaine 10 HP...
***
***             C.	C: Carb.
***  C..==        .==	H: Heads
***    /H/ ==>    /H/	O: Gear Box
*** O=/_/      O=/_/	(ASCII Diagram from a right view when sit)
***
*** (Any comments?  The theorie I got is that the head need less sucking to
***  get the gas but why the so much differences!)
***
*** (I don't have my Albestos suit handy... (;-} )

	From what I saw the '85 and the '89 didn't have any of the new goodies.
	But what might happened his that some guy has fit those on a VMAX.  A
	lot of VMax that I saw in Canada are a little tempered with...  Nitrus
	(spelling!), bypass, K&R intakes, 4-to-1 Kiemer(again spelling!),
	Progressive Rear suspension...

	But my choice goes for the plaine truth...  We've gone to the doctor
	yesterday, me and my bike.  I've order for $525 of parts (still some
	'previous owner crash' reconstitution) and fix a date for very heavy
	compression testing and maybe a engine wear inspection...

	With this year face-lift (a final one, at least for most of the bike
	except the engine and the gear box) that will make me a $4000 (CDN)
	bike looking and performing like a new one...  No too bad from what I've
	bring home 2 years ago (ITS MY FIRST BIKE!  And Yes I'm a two seasons
	newbie), from being stolen 1 time succesfully and another time with big
	damage to the electrical system, to the beating of a Bike-ass, to a
	55mph crash/slide...  "It will live Jim!"

	Have fun... (Yeah, a newbie on a VMX12 '85, serial number: xx0169 (;-})

	[ Somebody's selling his GSX(R) 1100 '89 for $5000, 14,000k, no crash
	  nor beaten...  Good, Bad...  I like those charming eyes... ]
