Frequently Asked Questions
Q: Does this piston require a specific break-in procedure?
A: Yes. Because of the specialized coatings, we recommend a heat-cycle break-in process. Allow the engine to reach operating temperature, then let it cool completely before repeating. Avoid sustained high-RPM operation for the first tank of fuel.
Q: Is this a standard compression piston?
A: Yes, this RE910M04700 kit is designed to OEM specifications for bore and compression ratio, making it an ideal drop-in performance replacement for your 85cc engine.
Expert Pro-Tip: When installing a new piston, never skip measuring your ring end gap. Even with premium pistons, checking the clearance ensures your rings won't butt together when the engine reaches racing temperatures. It takes two minutes and can save you from a catastrophic top-end failure.
