Ok, had the bike (pepi sport) running for long enough to go on an hour ride... Then it crapped out. Now it does that thing where I can get it to run but it won't idle slow enough to disengage the clutch. I examined the clutch and it's not siezed, moves freely by hand.
When I try to start the bike on the stand after it has sat it starts up easily and will idle (but too fast to disengage clutch) and if I rev the motor I get lots of white smoke, but the smoke goes away when the motor warms up. After a while of trying to start it and the motor warms up it becomes difficult to start, and when left to idle it craps out shortly after.
It's got a dellorto carb and I've cleaned it properly a few times, float seems fine, needle might be fine. There is only one adjustment (idle speed) and when I adjust for slower idle it craps out. The plug is relatively new. Bike does the same thing with the exhaust off. There is the proper fluid (sae30nd) at the proper level. I have also tried another carb from a same model bike on it and it still wouldn't work.
Anybody? Anything? Before I throw the bike off a cliff?
