Over time, it develops microscopic fatigue. Replacing it with a fresh bearing ensures the pin remains stable and prevents catastrophic failure that could destroy a new piston.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e After installing your new piston, perform a heat-cycle break-in. Run the engine until it reaches operating temperature, then let it cool completely. Repeat this 2–3 times to allow the piston and rings to properly \"seat\" to the cylinder walls before hitting the track or trail.\u003c\/p\u003e\n\u003ch3\u003eRecommended Pairings\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/mx-off-road-motorcycle-tools\"\u003eEssential Off-Road Motorcycle Tools\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/premium-motorcycle-chemicals-brake-fluid-bike-wash-coolant-chain-lubes\"\u003eHigh-Performance Premix Oil \u0026amp; Coolants\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
