Good To Know

Q: How do I confirm this piston kit fits my engine? A: Check that your engine calls for a standard bore of 80.23mm and that the part number 10574M08031 matches your application. Always verify piston size against your cylinder before ordering.

Q: Should the cylinder be honed before installing a new piston kit? A: Yes, a light hone helps the new rings seat properly against the cylinder wall. Inspect the bore for scoring or taper before assembly.

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