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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need to replace the wrist pin bearing when installing this kit?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003ch2\u003eExpert Pro-Tip\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003ch2\u003eRecommended Pairings\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-yz85-performance-parts-and-accessories-moto-house-mx\"\u003eYamaha YZ85 Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-2-stroke-dirt-bikes-performance-parts-accessories-moto-house-mx\"\u003eYamaha 2-Stroke Performance Parts\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/mx-off-road-motorcycle-tools\"\u003eEssential Maintenance \u0026amp; Motorcycle Tools\u003c\/a\u003e\u003c\/p\u003e\n\u003ch2\u003eAbout Moto-House MX\u003c\/h2\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
