[QUOTE="2strokesteve89, post: 176283, member: 1670"] Well I didn't see where the float height was checked, this could cause rich running and fouled or wet plug if not set correctly. But what concerns me is if there was gas in your transmission oil, I'm thinking either right side crank seal bad, or the case gasket had failed where the crankcase and transmission are separated,usually when crank seal fails the bike will still run, but blow LOTS of smoke and oil foul plugs, the failed gasket would allow fuel out of crankcase and into transmission, but if you got it running it would also blow a hell of a lot of smoke once either the seal or gasket failed, it would not only let gas out but suck oil into crankcase. Since you never saw the smoke when it was running previously, I would check your float level first, and set it correctly if needed. If this doesn't get ya going and you still believe there is fuel in oil, then you may have internal engine problems. [/QUOTE]
