os v spec problem
i have an os v spec with about two gallons on it ran fine till yesterday temp has always been 220 but it started smelling funny from the exhaust and now it wont hold a tune and the temp jumps all over the place. I took it a part and the piston and head are jet black like it is running super fat but it gets to hot. rear bearing feels perfect but the front feels a little funny any help would be great thanks
