    NOTE: Dennis Kirk recommends the following preliminary work to be performed by a qualified mechanic prior to installing new pistons. If the old piston has failed, determine the cause and remedy the problem before replacing. Air leaks and/or a lean fuel mixture are the two biggest causes of burned pistons. In cases where any part of the old piston is broken or burned through, the crankcase should be disassembled and throughly flushed of any debris.

    Our pistons, rings and kits are sold by application and bore size. Please note that STANDARD and OVERSIZES are not indicated. To get the correct part, you must know the standard bore size to make sure you are ordering either the standard or correct amount of oversize that you need. If you have any questions, please call Technical Service.

My piston measures 57mm. Is that the bore size? Or do I need to measure the jug to get the bore size
