Because this piston has a larger diameter (54.44 mm) than the factory stock piston, the cylinder must be professionally bored and honed to the 54.50 mm specification to ensure the correct piston-to-wall clearance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When installing an oversized piston, check your power valve clearance. Because you have increased the bore size, ensure that the power valve assembly does not make contact with the piston at any point during its travel to avoid catastrophic engine damage.\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 \u0026amp; Gear Oils\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.
