Frequently Asked Questions

Q: Should I measure my cylinder bore before installing this piston?
A: Absolutely. Even with a high-quality piston, always verify your cylinder tolerances. Proper clearance is critical for the long-term health and performance of 2-stroke engines.

Q: Do I need to replace the wrist pin bearing when installing this kit?
A: We highly recommend replacing your wrist pin bearing every time you install a new piston. It is an inexpensive insurance policy to prevent catastrophic engine failure.

Expert Pro-Tip

Expert Pro-Tip: When breaking in a new forged piston, avoid long periods of constant throttle. Vary your RPMs frequently during the first hour of riding to allow the piston rings to seat properly against the cylinder wall. This creates a much better seal and helps your engine maintain peak compression for a longer service life.
