Never use a metal razor blade or aggressive wire wheel on lightweight aluminum crankcase halves, as you can instantly gouge the metal and create a permanent leak path that no gasket can stop. Use a specialized plastic gasket scraper and a high-quality solvent or brake cleaner to dissolve old material. When installing the vital oil seals, coat the rubber lips lightly with fresh engine oil or assembly grease to prevent a \"dry start\" burn, and tape over any sharp splines on the transmission shafts so you don't cut the new seal edge during slide-on assembly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-yz250f-yz250fx-performance-parts-and-accessories\"\u003eYamaha YZ250F \/ YZ250FX Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-4-stroke-dirt-bikes-performance-parts-accessories-moto-house-mx\"\u003eYamaha 4-Stroke Performance Parts\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/mx-off-road-motorcycle-tools\"\u003ePremium Motorcycle Engine \u0026amp; Valve Tools\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
