Hey all, I was wondering if anyone can offer some insight into my bike rebuild. I have a 1986 vt500c, already put a lot of work into it.
It will start when jumped by a car and it revs beautifully when in neutral, there is absolutely no hesitation or coughs. The exhaust does heat up very quickly. Within one minute, the exhaust starts to smoke and will burn the hell out of my fingers (ask me how I know
), but the engine temps are still good.
When I put the bike in gear and try to run it, the bike needs constant throttle or it will die. It will barely move under it's own power. I drove it into the street just to see how it will run, ended up dying just before the ramp to my driveway. I jumped it again and was going full WOT just to get it to creep up my driveway, and having to play with the clutch to keep the revs up enough to where it wouldn't die.
I am 90% sure it has nothing to do with the carbs. I just rebuilt them and they are clean as a whistle, factory spec. I did have problems getting all the boots to sit right, could it be a problem there that would effect things this much?
I have a new rectifyer from Rick's Motorsports on order, I figure that might be the problem with starting it, since my battery is checking out okay. I'm not sure that explains the bogging down when in gear. Would the stator have anything to do with that? Pulse generator?
Plugs have been replaced, and when I pulled the old ones, they were ashy white, indicating a lean mixture, right? I've checked my fuel supply thoroughly, and float bowls definitely fill with gas. I did put an aftermarket fuel filter on the bike, but the problems remain whether it is on or off.
I would appreciate any insight you all may have to offer! I'm definitely a beginner mechanic, but I've learned a lot already working on this thing. I'm not afraid to learn a little more, I love this bike and will not stop until I get it running like it should!
