boost

I just bought a 1988 and the controller for the V boost does not work. :bang head: Anyone know where I can get one? I would like a new OEM, ARE THERE ANY? Is there a aftermarket part I could use ? There are some OEM ones used on Ebay but how do I know there any good? Thanks

Yes, you read that correctly, the newest Harley-Davidson is a bike sure to bring many new owners into the fold. Turning their back on the aging Baby Boomer cruiser-purchasing cohort, H-D has released a stylish scrambler which reportedly will sell for less than $6,500. Given that many of their...

97 VMAX 25K ; Ive read some of the Vboost how to's and My understanding is the Vboost can be disconected in the open position. Questions ; by disconecting does this mean it will always be in vboost mode at any rpm and the bike will always get the vboost benefit at all rpms ? Also does...

Gidday. I got my bike a few months ago. I havent had a chance to ride it much as the forks puked oil on the way home and and since repaired Ive been busy. I was told by the seller it had the vboost set to come in at 3000rpm. This feels right as it picks up a fair bit at 3k. I looked here on...

Hi. When i turn ignition on from key, my boost servo don't do initial check, open/close. However, when motor running and revs are around 6000 the servo motor pulls boost open.?? I have measured +- cable's and when ignition on, there is no voltage coming from boost control unit. The thing is...

Got another Vmax. The previous owner wired a toggle switch for the Vboost. I believe it put on the V boost all the time or at least at the lower RPM. I would like the VBoost to operate like factory stock. Do you think I can just leave the toggle switch in the off position? Or, would that...

Hello i`m a new member from the sunshine coast b.c. I have a 2007 max with a problem with the v boost, I have had the motor out of the bike for a partial rebuild (for ingesting a small piece of metal ,I will tell another time.) I have a flat spot @7000rpm. From 6000 to there its opening, then...

My controler has to be lightly tapped to get it to work when key is turned on.how can i fix this or does it have to be replaced.the previous owner had the boost unplugged so it was open all the time.it started overheating once the air temp warmed up so i plugged it back in.it ran great but only...

Hi guys, I just picked up a '92 Vmax, she's been a bit neglected and I've stripped it down. Question, It has a switch on the front which the last owner, who had no motor knowledge at all, said was already fitted previously. I know it alters the Revs the V Boost comes in, but can someone tell me...

Whattup all! So, Im thinking about putting one of the hyperchargers on my 2009 1100 vstar classic. Does anyone know what the actual HP boost would be? I hear alot of people talking about the noticeable difference, but Im not hearing any numbers. Any info is super appreciated! Thanks brothers! ~Gary

It must be a sign not to ride on Memorial day. Last time it was a R/R that went bad. So I decided to go for a ride today only to find out the boost is not working. I ride home to see what it may be. All the fuses were good. Turn the key on and boost works. Thought it was just a bad connection...

When I bought my bike the guy said he broke the tboost switch that was installed. its a little rectangle switch with 3 terminals but there is only a black wire and a red wire installed leaving one empty terminal on the switch. I bought a 3 position switch from Car Qust to replace the broken...
