I just bought this 350l and had removed the carb and cleaned it. The bike runs great. I havent had much of a chance to test ride it in the daylight. I noticed this weekend that under accell the thing leaves a trail of lingering smoke that kind of smells like burning oil. I know they smoke but it seems excessive. The engine idle great and runs good to. I was wondering if maybe its running slightly lean. ANy ideas on what to check would be great.

Check the return spring on the oil pump. Mine had broken and the pump was wide open, I used a tank of oil to a tank of fuel (way to much). Pull the pump cover and operate the lever by hand and see if it returns by itself. Buddy
