I have a Tao Tao 110cc that I just purchased this past December. It has ran fine for a couple of months but now is producing a white smoke from the exhaust pipe and it only seems to be noticeable after the quad has been warmed up and rode for about 20ish minutes or so. Also I can only see the smoke when coming to a slow down from releasing the throttle. When I'm in WOT, I don't see any smoke from what I can tell. Doesn't seem to smoke in idle neither. Oil is clean and fresh and the oil level is fine as well. Anyone know what else I can check into?

 

Sounds like a slight oil blow by past the rings or possibly from the valve guide seals. I'd just keep a check on oil level. If it gets worse,or oil level starts dropping,then you may have to do something about it.
