[QUOTE="Mooney 78865, post: 26994, member: 175"] For what it's worth. Is this the fuel that was in the bike? Or did you mix new? How long did the bike sit before you ran it? Was the gas off to the carb while it sat? Reason I ask is 5 min is not enough time to get an accurate read on the jetting. Piston and cylinder temps will take that long or longer to stabilize. "Painting the fender black" in 5 min really makes me think WAY wrong ratio, or wrong oil for the pre mix. 2 strokes do not leave crap on the bike if set up correctly. A small amount around the silencer is OK, not on the fender or even worse running down the pipe. I have some experience with 2 stroke engines: I currently have a KTM 300 XCW (e) run Motorex full synthetic at 60:1(recomended, and I don't think I know more than the designers at KTM) I have had 2 TZ 250s, a YZR 500, and a TZ 750. All two strokes. All run with pre mix at 40:1. Old school I know. Bottom line, find out what the manufacture recomends for pre mix oil and ratio. If necessary do a leak down, (2 strokes do love crankcase pressure) this will tell you A LOT! Have now officially broken my first rule of forum posting.
