While it is factory-trued and ready to drop in, we highly recommend purchasing a fresh set of main bearings and oil seals to ensure your bottom end is completely sealed and smooth for the life of the new crank.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this a direct drop-in replacement for the stock crank?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes, this is designed to fit your YZ85 engine without case modifications. However, because it is a stroker crank, it will change your engine's compression and timing characteristics, so it is vital to ensure your top end and jetting are tuned accordingly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When installing a new crankshaft, never use a hammer to force the crank into the cases or bearings. Use a proper crank puller tool. Even a minor misalignment during installation can cause vibration, leading to premature bearing failure or crank runout. Patience during the bottom-end assembly is the difference between a motor that lasts one season and one that lasts three.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003e\no \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\u003e\no \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\u003e\no \u003ca href=\"https:\/\/motohousemx.com\/collections\/mx-off-road-motorcycle-tools\"\u003eEssential Motorcycle Shop Tools\u003c\/a\u003e\u003c\/p\u003e\n\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.
