A small leak at the cylinder port can significantly hurt performance and may cause your bike to run lean, which can lead to engine damage. A thin layer of high-temp silicone sealant on the O-rings can help ensure a leak-proof seal.\u003c\/p\u003e\n\n  \u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003e\n  o    \u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-yz65\"\u003eYamaha YZ65 Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003cbr\u003e\n  o    \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\n  o    \u003ca href=\"https:\/\/motohousemx.com\/collections\/mx-off-road-motorcycle-tools\"\u003eEssential Engine \u0026amp; Chassis Tools\u003c\/a\u003e\u003c\/p\u003e\n\n  \u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
