Always apply a quality 4-stroke assembly lube to the rod bearings, main bearings, and transmission gears, and always use a dedicated crank puller tool to draw the crankshaft smoothly into the center cases without side-loading the main bearings.\u003c\/p\u003e\n\u003ch3\u003eRecommended Pairings:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/kawasaki-kx250f-performance-upgrades-engine-mods-and-accessories-moto-house-mx\"\u003eKawasaki KX250F Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/kawasaki-4-stroke-dirt-bikes-performance-parts-accessories-moto-house-mx\"\u003eKawasaki 4-Stroke Dirt Bikes Performance Parts\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/mx-off-road-motorcycle-tools\"\u003eMotorcycle Tools Performance Parts\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.
