Good To Know

Q: Can this piston kit be used with the original cylinder? A: Yes, it is designed for a .020 over bore, which requires re-sizing the cylinder to match the piston. Confirm your cylinder bore condition before ordering.

Q: Are there any special break-in procedures? A: Follow standard snowmobile engine break-in guidelines: vary RPM, avoid prolonged full throttle, and change oil after the first few hours of operation.

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