So during my first long rides with the vmax I noticed a buzzing would come on complelty randomly while in any gear above 2nd and last for about 20 seconds or until I downshift into first. Super weird. I belive have an igitech vboost sytem and the noise sorta sounds like the vboost opening up...

kinda stupid question but i still cant understand it. My 1988 VMAX doesnt have the vboost controller yet it does the servo noise on startup and i feel a pull when im in high rpms. What exactly does the controller do and is the vboost functional without it? HELP PLZ! (also the cylindrical plug...

Hi guys, happened on my last ride of this season a day ago.. Left me stranded, waiting for tow truck now. No start, slow to turn over, rode great until stopped and turned off. Battery is 2 years old(?) I think. Waiting 2 hours now, almost got started, but no. Tried 2 jump starts and no...

Last year i bought a 1985 vmx 1200. When i started the bike in january i saw smoke coming from an coupling and traced it to the voltage recitifier regulator. The heat-shrink tubing was melted into the isolation, and some of the isolation was gone so i saw the copper. I changed and started the...

I drove my 2016 vmax to my German club for a bier. No issues. It rocked. Went to get on it to go home. It took a lot of cranking and a lot of throttle to get it to stay lit. After revving for 5 minutes, it finally idled. It smoked while it warmed up smoke poured out. You could smell the...

My left side rear spark plug is not firing on my 1996 V-Max. Changed the plugs Checked the wires (nothing obvious) Checked the coils (also nothing obvious) Started it in the dark and there seems to be a spark that flickers briefly but it is so quick, I can't see where it is at. The spark doesn't...

Ok, so I've scoured every parts list, and I've done my due-diligence to find an answer and have failed......I want to slim down the turn signals, but it seems any aftermarket options I look at would have too small of a stud compared to the OEM turn signal stud. Does anybody have a list of turn...

New guy here. So I've been having the whole hot start normal issue. I decided to the fix and followed RaWarrior's Stickie on "How To". I'm having this problem (Not sure if this was pre-existing before the mod): Basic Info: It's an 89 with 28,308 miles. not sure what the previous owner...

Hey guys and gals. Out riding the 86 max yeaterday and it was running great! A few hours in, the bike started losing power and sounded like the the carbs were loading up. Then in heavy traffic, it stalled. Got it fired back up after waiting a few minutes, then it died again. Tried to start back...

Not sure if you guys have ever played with these.... but they're solder seal heat shrink connectors. They work fantastic. Twist together two wires, put the connector over them... heat gun or lighter. Boom it works without issues. The solder is low enough temp that it tins both wires and...

This past summer I've purchased a Sena 20S bluetooth module for my helmet. All works as expected except for the built in FM Tuner. When the vmax is turned off, all works crisp and clear as it should, but as soon as you turn the vmax to ACC on, all goes static on every station? I've...

A few weeks back I posted about ongoing issues I'm having with my Vmax. Long story short.... a few had mentioned to contact Sean and get his electrical test kit. I received it today and HOLY CRAP! So much stuff in there! He even sent a full set of carbs... unbelievable! I can't even imagine how...

Hi all, Just wondering if anyone in Australia offers the COPS setup for Gen1 Vmax? My 88 max has been playing up lately... the usual kicking, bucking, surging etc.. Did the shotgun and rode it 2 weeks ago, it was running the best it ever has - so much so that at approx. 125km/h decided to...

The good news is I already was half-way over the Brooklyn Bridge, so I didn't have to push the VMax too far, as most of the trek was downhill. Nice 80 degree day, around 50mph at 3000rpm in 3rd, fan override switch on, temp halfway up the gauge. I smell something similar to plastic burning...

Who's good at this? I thought I was being that I've been doing it for 16 years now.... That being said, My LED headlight came in the mail and I decided to install the smart switch and a SAE hook-up since I was gonna have it all apart anyway hiding wires. Got it all tucked away and before I...

Hello, I have been looking through the forums for a while now trying to find a fix for my fuel pump. I bought a new pump, thinking my old one went bad, but it was not the issue. Whenever I turn the ignition on, i can hear the (vboost?) working, but the usually ticking of the pump had...

Hi guys, Last night, my wife and I took a quick ride up to a local state park to watch the sun set. All was good until we were ready to head home. I turn the key on, everything comes on as usual. I hit the start button and the whole electrical system dies (no headlight, no dash lights). I...

checked my fuse and its fine . my headlight (high n low) doesnt work and neither do my dash lights . turn signals still work . anybody have an idea ? thanks

Hello all, I have a '96 Vmax that has an odd electrical issue. Bike fires up fine(new battery& plugs installed before issue). Bike has COP, V-boost switch, & fan switch-all work normally. Never had a problem until 3 weeks ago. Riding along it backfires then stalls. Pulled over, re-started...
