[QUOTE="Pappy, post: 382418, member: 3278"] I realize we are looking at what is essentially second hand information. Usually, when a 2-stroke pops a piston, the first thing to go is the idle quality. So....I question the validity of the troubleshooting of the "mechanic" or the quality of the information we are seeing. Will be really difficult to give much help until more, and more accurate information heads this way. Second....only the standard bore OEM piston is not available. The .030 OEM pistons are still available. Aftermarkets are available in both sizes. I see no big roadblocks so far. [/QUOTE]
