Good To Know

Q: Do I need to replace the cylinder when using this piston? A: No, this is a standard bore kit for a stock cylinder. As long as the cylinder is not worn beyond limits, you can reuse it after honing.

Q: What else should I replace during a top‑end rebuild? A: It is recommended to also replace the gaskets, valve seals, and check the valve clearance for a complete job.

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