Even if a seal looks okay, it has likely lost its pliability. Reusing old seals is the most common cause of \"mystery\" air leaks that make an engine impossible to tune correctly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this kit include valve stem seals?\u003c\/strong\u003e\u003cbr\u003e\nA: No, this kit is specifically designed for the YZ65 and YZ85 2-stroke engines, which do not utilize valve stem seals.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When installing new crankshaft seals, always apply a light coating of clean engine oil or grease to the seal lip. This prevents the rubber from dry-friction burning during the first few rotations of the engine before the oil pump or splash lubrication takes over.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003e\n• \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\n• \u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-yz65\"\u003eYamaha YZ65 Performance Parts\u003c\/a\u003e\u003cbr\u003e\n• \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\u003c\/p\u003e\n\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
