Specs At A Glance

Good To Know

Q: Does this piston kit fit a stock, unbored cylinder? A: No, this kit is sized at 82.00 mm for a cylinder that has been bored .040 over, so the bore must be machined to match before installation.

Q: Is machine work required when installing this kit? A: Yes, the cylinder must be bored and honed to the correct clearance for the 82.00 mm piston, and ring end gap should be checked during assembly.

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