vboost

Hey guys , was hoping someone could shed light on my problem. My servo works most of time and moves the black box at end of cable. Problem is the box isnt connected to anything and jut slides back and forth in the metal sleeve. Rather than pulling carbs and fixing has anyone just manually opend...

i know there is a thred somewhere about how to set it up to have vboost on all the time but i cant find it atm so can anyone help me out?

Hi guys, I got a problem with my vboost control unit. It is not working properly. When turning the ignition key it wil not make the servo Motor work. So nu buzzing. When i press on the vboost unit it works every time. I guess it is broken, the circuit board. Any of u have any...

Since the carb is getting additional fuel from the adjacent carb, how is it getting the additional fuel with the advent of the additional air?

Well, since my boost controler has crapped out, and I would rather not fork up the bucks to replace it, I tried jumpering the servo to leave the boost open and gave it a test run. Ran great above 5 grand as long as the throttle was cranked open. Ran terrible at lower rpms and low cruise speeds...

Past 2 days I haven't been feeling the trademark acceleration. I do hear the servo when I flip the kill switch and my acceleration is still fast enough to illuminate my oil level light but I don't get that flying off the seat feeling. Hopefully I'm just getting used to the acceleration! If I...

OK, I peeled off most of the resin and re-soldered some places and cleaned corrosion other places, even solder bridged a place, and now boost works great! Wasn't sure what to do about corrosion control, and I HAD to test ride it right away, so I gave the PC side of the controller a light shot...

Hi all, My vboost hasn't been cycling upon turning the key lately, among other electrical problems, and I read a thread recently about them being prone to loose connections that may be fixable, so I decided to investigate. I noticed today that flexing the vboost box made the servo and fuel...

Hi! My 88 has had the vboost assembly removed. I have a 2002 assembly on hand, that i want to buy and install on my bike. Will it work? Does the 02 controller talk to the 88 ECU?

Just recently bought a 2000 and the v-boost kicks in around 6000rpm, Does anyone know how to adjust it so it kicks in sooner like around 4500rpm? Or can you completely turn it off so its on fulltime?

Forgot I made this video. With the vboost disconnected you can see the idle changes from having the butterfly valve left open. I didnt ride it like this, but I would assume that it would be soggy. Hence the reason why you see the vboost tuner kits that let you open your vboost sooner, make...

Hello chaps, I'm going to be removing my vboost system in order to fit my supercharger (that's the plan anyway). Am I right in thinking that the whole vboost set-up consists of the controller, the motor/solenoid and the set of intakes with the butterfly valves? Or is there more to it...

I've been reading up on vboost controllers and I've read a lot of conflicting info so I figured I'd ask here............ I'm looking for something that will: -shut the vboost completely off -let the vboost function normally (6k) -have either an "always on" setting or an "instant on"...

Does anyone do this kind of work? I replaced my controller last summer, because the old one was only working intermittently. The new one is fine, and I still have the old one. If anyone repairs these, I will be happy to donate my old one for the cause. I'm thinking if someone does this kind of...

Hi all, keep in mind that I am riding with a half helmet and windshield, so I hear a lot more sounds than most, prolly. First, when I nail it, around 6k up I can hear a light high pitched hammering sounds from the engine. Not that loud, but loudest thing this normaly quiet running engine is...

From specs I figure v-boost may gain 45-50 horsepower over non-v-boost (Ero vs. usa/Canada bikes). Does anyone have dyno results showing the different torque and HP of the same bike with v boost off, then on again (ran to redline) ?

Powered up my barnfind Vmax yesterday. Since it hasn't run in 4 years, I decided to spray some oil down the intakes and spin the motor up some, without plugs, to limber it up some before installing my freshly rebuilt carbs. I left the plugs plugged in and hanging and grounded them with...

:ummm: Hey guys, got a question for ya. How do I know if the V-Boost on my bike is actually working? Is there a way to test it somehow? Being this is my 1st Vmax, I'm still learning all the little secrets about it. Thanks.

just got my micro machines boost controller. its not covered in epoxy like the stock one. do I need to do anything to it, or stick it in the stock box and enjoy

(I'd swear I've asked this question before, but I can't find where, so feel free to redirect me) I bought a '94 a couple of years ago and soon discovered that it did not have V-Boost installed at all. It runs great (mostly) so I haven't thought much about it until now. I'm planning to do some...
