Good To Know

Q: Will these pistons fit without boring my cylinders? A: These are standard bore pistons, so they fit cylinders that remain within the factory standard bore tolerance. Scored or heavily worn cylinders may need boring to an oversize first.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
