Specs At A Glance

Good To Know

Q: Do I need to re-bore my cylinder to use this piston? A: Yes, this is an oversize piston; the cylinder must be bored to 101.5mm and honed to the proper clearance for correct fit.

Q: Are the gaskets included in this kit sufficient for a full engine reassembly? A: The gasket kit covers all major engine gaskets including head, base, and top-end seals, though separate crankcase seals may be required depending on your rebuild.

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