Good To Know

Q: Will this piston kit work with stock cylinder bore? A: No, the .020 over bore piston requires the cylinder to be bored to match the 48.5mm diameter; consult your engine builder for proper sizing.

Q: Do I need to replace the wrist pin bearing? A: Yes, it is recommended to install a new wrist pin bearing during the rebuild to ensure proper fit and reliability; the kit includes the wrist pin but not the bearing.

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