Good To Know

Q: Does this kit come with a piston pin bearing? A: No, the wrist pin bearing is not included and should be ordered separately if needed.

Q: What is the recommended break-in procedure after installing this top end kit? A: Follow a standard two-stroke break-in cycle: allow engine to warm up and vary speeds for the first hour, avoiding sustained full throttle.

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