Good To Know

Q: Does this piston require cylinder boring? A: Yes, a .020 oversize piston requires the cylinder to be bored and honed to 81.50mm for proper piston-to-wall clearance.

Q: Can I install just one piston? A: It is best to replace pistons as a set and check ring end gap and cylinder condition before assembly for even compression across cylinders.

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