Specs At A Glance

Good To Know

Q: Is a break-in required for the new piston and cylinder? A: A brief break-in with a 50:1 fuel mix and varying throttle is recommended to seat the rings properly before full-load operation.

Q: Can the old circlips be reused? A: Always install the new circlips supplied in the kit to ensure secure piston retention and avoid engine damage.

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