got the bits so how do i vencher to the max

[hell yea]

hy gys just scord sum vmax stuff heads cams vboost manafold can i just bolt this stuff on to my 83 ferst gen our do i have to mod stuff and what kind of diferance will it make ?

allso are the 1gen carbys diferant and will i have to re jet them to suet the vboost ?

aney experienced advice would be much appreciated like will the carbys fit our is there a mod that has to be dun ect ?

I seem to recall, that the parts, simply do not physically fit on top of the Venture, engine. But if you are handy with a welder, etc. etc. then modification can be made to make the stuff fit.

But as I recall, it has been done !! ( find that guy, and talk to him )

 

Also, you will need a " Barnett Clutch " to handle the extra power.

 

RE-jetting ??? well you won't know that untill the project is done, and you get into test driveing, and tuneing, Syncing ?? and things like that.

 

Most likley you would be " Re Jetting " !!!

From what I've read in the past, you want to talk to Dingy.

His yellow project runs OK

[hell yea]

was just wondering what mod i have to make to get this dun and running well

It all depends on how much you want out of the bike, and how much time & money you want to invest.

 

The VMax heads only is a straight forward swap for the Venture heads. Only real change is the side plate that covers the cylinder pocket drain plug (sometimes called a freeze plug, which it isn't). This needs to be a VMax cover, the Venture plate is longer and covers part of head.

 

Carbs will need mains and one of the air jets changed with the VMax heads. Also needle valves should be changed to a VMax set. A set of carbs from an 86-93 Venture or a VMax are better due to being larger venturi size. You can not do this, but it will idle like crap and not develop power potential, trust me on this one.

 

The heads will probably need completely cleaned inside by sand blasting. This requires valves to be removed, which should be reseated by lapping. New valve guide seals also.

 

The VBoost is a whole nother can of worms. In addition to the VBoost intake assembly, a servo motor and mounting bracket is needed to operate manifold butterflies. It will not fit on the Venture in the same place it does on a VMax due to VMax's only have front coils mounted below TCI. Rear pair of coils are mounted on back end. This allows a space to mount servo motor. If you want servo motor to operate the way a VMax does, which is opening intake butterflies at 5,700 RPM's, a servo motor controller is needed. Or an Ignitech TCI can be used to replace stock TCI and it can control servo.

 

A really tough part of getting VBoost intakes to fit is a clearance issue with the #1 carb and frame. The VBoost intakes are about 1 1/4" taller than stock. This creates an issue with #1 carb when carb rack is being installed, it just won't slide back far enough to drop into the rather stiff carb intake boots. I had to heat frame with torch at contact point and 'dimple' tube in some to get clearance to get carbs in and out. The stock air intake box will fit on the carbs without modification.

 

Next problem is the throttle cables interfere with frame in stock configuration and need modified with VBoost intake. And the choke cable needs modified.

 

The coolant line out of the Twinkie on the right side needs modified with VBoost.

 

There is little difference in the lower end except for doming on VMax pistons raises compression a little. There is also a slight difference in the oil galley, the VMax has an extra bearing oiler line on it. The piston doming difference can be compensated for by either milling block head deck about 0.040" or installing thinner Comitec (sp?) head gaskets.

 

As mentioned, the clutch should be upgraded. I didn't go Barnett route as it has limited upgrade possibilities. I used a diaphragm clutch from a 86-93 style motor and doubled the diaphragm springs. This requires a clutch cover also from an 86-93 block. You really need a strong grip on left hand as this increases pull force on lever, but it don't slip if done right.

 

As I said, it depends one where you want to go with this. I would guesstimate $500 to $1000 to get it running decently. Carb rebuild alone, done right is at least $300 and up.

 

Speed isn't cheap or easy. But it is an adrenalin rush.

[hell yea]

thank you thats what i needed to know

[IronMike]

When I want a speed induced adrenaline rush, I just go WOT and close my eyes!

 

Cheapest way I have found, That sounds like a LOT of WORK and gets into riding time. Good job of enlightening us on the task though, got my respect for doing all that. What a project!

[sandman]

Gary; I think you left out that cam gears need slotted if you change deck height. Even if you just use thin gaskets it will retard the valve timing.

That's only chapter 3 & 4 of the book of Tweety.

This has been a multi year project.

In first I have put V boost on a stock engine 1200, then I put cylinder head V max on my 1200 engine venture, this is french' s cams (more power in low), carburators are 1200 venture with jet of 1300, I short cut air box because too hight with pipes V max, and modification inside.My V boost is manuel I open with the command of choke, you open when you want, and it' s funny have twos accelerators........it' s not a " dragster " but I have win fews power.
