Good To Know

Q: Is this kit a direct replacement for the stock engine parts? A: It is sized to standard 66.40 mm bore and is intended to replace the original piston, crankshaft and gaskets as a matched set. Confirm the cylinder is at standard bore before ordering.

Q: What else should be checked during this rebuild? A: Cylinder plating, bearings and clearances should be inspected before assembly. Measuring the bore and checking the crank fit helps ensure the new parts seat correctly.

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