problem

I have a slow discharge at my battery, which runs my battery dead overnight. I hook my volt meter to the battery, and every 30 seconds to 1 minute,I can see the battery drop 1/100 of a volt. Example, battery reads 12.66 volts, and you can see it drop to 12.65, then in another 30sec to 1min, it...

Hello, I'm trying to reinstall the stock vboost system after removing an S7 kit; I want to put the bike back to OEM. Not having done this before I'm having a few challenges. My immediate problem is that I don't see an easy way to install the 2 screws that hold the servo/ motor thing in place...

When I swapped my battery from the 2000 to the '86, I noticed the negative pole was covered in green gunk, which wasn't there when I looked a couple of months before. I also noticed that the negative pole bolt nut had been eating up by that green gunk - replaced it with a new one. Then when my...

I have done a little work on the bike I have acquired recently, now after reassembling, I have a small issue. I can start the bike, for a few seconds, it revs up to about 4k then dies out . I can hear the fuel pump click on, for a few seconds, the the fuel pump relay seems to be working. Is...

Hello, I've recently replaced my front headlight with 3 smaller ones. From what I understand the stock bulb is a 50-60 WATT lamp, now there are 3 100 WATT lamps connected in parallel which in turn drains the battery in a few minutes. I'm trying to find a way to make the headlights work...

Hey Guys, I've got a problem that I cant figure out to save my life...Almost 3yrs ago, I got a 86 Yamaha Vmax with 18k on it. The guy I got it from said it would need a battery, because it was weak. Put a new battery in it , and every thing seemed fine for about 3 months.The battery started...

Hi, Recently I bought a V-max that was standing a long time. I replaced the battery, oil, filters, made ​​complete basic maintenance. I am now having a problem that I believe is the fuel pump, please see the following video: http://www.youtube.com/watch?v=qDBCt006tOU The 'tec tec tec"...

My '04 has 19,000 miles, a full Mark's exhaust and Morley jet kit installed 2 years ago. For the last several months the bike has refused to idle and has a serious miss/hiccup between 3000 and 3500. It runs fine at full throttle, but around town hesistates and stumbles under 4000. We removed...

See if you can figure this one out....:biglaugh: The '96 I just got runs pretty good but requires full choke to start and seems to be a little finicky about starting. It will idle after warming up but there are persistent backfires while idling....throttle response is immediate with no...

First of all I?d like to thank you all Vmax friends on the forum ,,, actually , I removed the carb out from the manifold, cleaned the four carbs and replaced the damaged rubber joints between the manifold and the V boost , and replaced the four air/fuel screws , rebuild the manifold, tuned the V...

Hey everyone, Im quite confused about a carb sync problem I've been having with my 94 v-max. I run my bike for about 5 mins then sink up carb number 1 with carb number 2 and all seems okay. However, when I try to sync carb number 3 with 4, the engine starts to drop from 1000 rpm and dies before...

Hi, This summer I added a Mark's 4-2 exhaust and Morley Muscle jet carb kit overhauling the carbs. Immediate increase in power was observed, along with some very minor popping at 3-4k in 1st, 2nd. Being an expert in denial, I ignored the symptom. Weeks later the popping became worse...

Went through the carbs again last night to have a look and change some jetting and think I found a problem causing my heavy rich issue at idle and up. Underneath the jet block there is anl o-ring that goes around the brass tube that the needle slides in to. There is a sligh bevel on the back...

Hi all I have a problem that is driving me crazy. I have no ignition switch i have a regular switch that colses a master relay that allows from teh voltage to go from the battery to the fuse box, the only hot circuit is the starter relay power wire. After i did my rebuild i got a problem that...

Hey Guys. I have a 86 Vmax , just got back from the Tail of the Dragon last week. Lots of fun!! Anyways, took the bike to work , no problems. on my way home, I got on I-95 and opened it up. Was in 4th gear about 7500rpm and lost power. It seems like a fuel problem . Anything above 4000 revs the...

Ok so I have a 94 max and had the motor rebuilt and after I put the bike back together I had a problem with the bike at open throttle. It would sputter like it was miss firing and would get sluggish like barely accelerating. It would start at 4000 and it would get up and go at about 6000. I...

I know I've been "out of the loop" for a while...please forgive me! Now, this question isn't regarding our beloved Max, but... I recently acquired a 1994 Honda CB1000 (known as "The Big One") and I've run into an interesting carb problem. Now, let me preface this by saying that I did have...

So me and my buddy installed my new tack a few days ago. After a few hours and lots of turning the bike on and off, we got it all sorted, by that time it was a bit late and he needed to get home, and I needed to go to bed. The next day we planed a ride, so I get on my bike, attempt to get it...

OK it's done it to me twice now.My '92 is running just fine then all of a sudden it starts popping real bad thru the exhaust,dies and won't restart.First time for a day second time for an hour.Then it restarts and runs fine.When it tries to restart it right away it will sometimes restart,idle...
