Good To Know

Q: Is this piston compatible with a stock cylinder after boring? A: Yes, the cylinder must be bored to .040 over to match this piston size.

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