Good To Know

Q: Do I need any additional parts to complete the rebuild? A: This kit includes the wrist pin, circlips, and gaskets, but you may need new valve seals, cylinder head bolts, and engine oil for a full top end service.

Q: Is this kit suitable for a high-compression setup? A: This standard bore kit is intended for stock compression; for high-compression builds, consider Namura's Size B or C piston options.

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