1996 Vulcan 800 classic...I work on this bike for a good friend and just had it hauled to me for some work. She complained that gas was flowing from it and dripping from the engine. Then it was mentioned that the "little bottle" was full. Ok, I said it sounds like the float is sticking. Well, upon checking, yep, you try to start and the gas starts to flow out the overflow..I tapped on the carb and it appeared to stop and though maybe just a little gunk on the seat/needle. The spark plugs were gas fouled and the cylinders were loaded with gas. I cranked the motor a few times to blow out the excess fuel, cleaned the plugs and reinstalled. Bike fired up, but had trouble idling with air cleaner cover on. After a bit it seemed to be ok. I dumped some fuel cleaner in the tank and set out for a test run...well, didn't make it far..got about 1/2 - 3/4 mile up the road and started losing power, then some knocking and then died. Air cleaner cover was hot! Let sit for a couple of minutes and pulled cover off -- yep, I was on fire a bit..I tried starting the bike and it would start, but would continue to backfire through the carb if any throttle was applied..I'm suspecting that the carb is still dumping too much fuel in the cylinders, hence a rebuild is order....thoughts, suggestions, recommendations?
