stage 7 with enabled v-boost , YAMAHA FACTORY SETTING v-boost cable on slot no 1, this way the v-boost works in perfect harmony with the stage 7 on the vmax, WOT IS BACK

I'm new to the Vmax (coming up on a year) and this forum. Hope this is the right place to ask this question. Don't think the Vboost is working. When I first got the bike, very noticeable when you hit 6K rpm it was like a little nitrous kick. Now nothing. Bone stock 2001 engine. Now that I...

Hey all. I recently put on an IXIL exhaust like KJ's and now I am running pretty rich. Was going to try and get it dialed in this weekend but had a few questions. After looking at the factorypro website about tuning cv carbs, I was wondering if the vboost makes it harder to choose the main...

my vmax has been sitting a lot this winter. i noticed on occasion that when i would ride it after sitting a couple of weeks the vboost would come in after a few tries, but today it isn't coming in at all. think the gas is fairly fresh. what would "stick" on these, causing this? mine's an '86...

Hi Guys, My mechanic just finished replacing my old engine with new one. He never did that before on Vmax and I explained him about the VBoost mechanism. He said it didn't have any special issues with it BUT, now after the new engine installed whenever I reach 6000rpm the bike is turned off...

This has probably been ask and answered before but I can't find it so here go's. I have an 88 Vmax that I rebuilt the carbs on and now the v-boost is not working. I ran all the test and am fairly sure it is the controller. The factory controller is over $200 and the one from micro something is...

I'm probably very ignorant in asking this but whatever, if you don't ask you wont learn! So my question is, why have a V-Boost system? Why not have slightly bigger carbs and inlet manifolds? I'd say it would be a lot cheaper to set up and there is more than enough room to install them.

I read something about being able to adjust the VBoost setting. Is this possible and what if anything would it do to the engine wear or fuel economy? Also what are my options for upgrading the exhaust with out having to go through a huge hassle with jetting or air issues?

im attempting my first carb sync on the vmax .Does the vboost need to be disconnected or closed ,and how do i tell if it is?thanks in advance billy

Hi guys I have a friend that wants to install VBoost on a European model so he can go get those extra 40hp beyond 6K rpms. Does anyone know if the European model electrical harness allows for installation of the VBoost? ie does it have the wiring and connectors for the controller and all the...

I have a 1993 VMax with a TBoost installation. I have had the bike since 2005. The VBoost has been working perfectly all this time. Even after I installed the TBoost, 4 years ago, everything worked as it should, 3K, 6K, off. The first time I noticed any problem was 2 weeks ago. I went out for a...

So I bought a 93 Max and when I asked the guy about the toggle switch on the throttle holder he told me that 93 was the first year to put that toggle switch in. I knew he was telling a story, or as I found out later, was told that. So I figured, by the miles and the guy having the bike for 2...

Hello, Does anybody know in what position the lockbolt is supposed to be on the vboost in order to function properly? Also, is the procedure found in the manual correct in terms of vboost lockbolt placement?

I am currently running with the VBoost wide open. I have the servo and controller removed and I took a piece of brake line (metal tubing) cut a slit in it with a dremel down the length of the tube, slid the vboost wire in it and let the metal end rest on the outside (hopefully that makes sense)...

Hello, When adjusting the vboost, the control cable, and a set screw are involved. When synchronizing the vboost, a set screw is involved. My question is.... where should the locking bolt be when the control cable is adjusted, towards the back of the engine, middle, or front of the...

This is a 1988 model that I purchased used a month or so ago, but just now getting arounnd to working on it. The bike has not been maintained, and about everything on it is original except the tires. I suspected that the Vboost had been bypassed or not working on this bike, but didn't think...

I read the FAQ and some other threads, but still have a question. The Vboost is a tube with butterflies between the manifolds on each bank that opens at 6,000 rpm. Does the VMax engine normally use 1 carb per engine side(or 2 cylinders), then when VBoost kicks in it opens an additional carb per...
