Re: Bike won't run over 20 mph, sputtering idle

Have you tried running the bike in "prime"? If this gets it running normally, then your problem is a vacuum leak from engine to petcock. If you haven't already tried this, then give it a go, & let us know the result. :2tup: However, it seems to point to a carb problem.
