We highly recommend re-jetting your carburetor to match the increased exhaust flow for maximum reliability and power.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When installing a new 2-stroke pipe, don't forget to replace your exhaust O-rings. A fresh seal prevents pressurized exhaust gas from leaking at the header, which causes a loss of bottom-end \"snap\" and prevents messy oil buildup on your engine cases.\u003c\/p\u003e\n\u003ch2\u003eRecommended Pairings:\u003c\/h2\u003e\n\u003cp\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/unlock-peak-performance-for-your-yamaha-yz125-high-quality-parts-accessories\"\u003eYamaha YZ125 Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003cbr\u003eo \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\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/premium-motorcycle-chemicals-brake-fluid-bike-wash-coolant-chain-lubes\"\u003ePremium Motorcycle Chemicals \u0026amp; Maintenance\u003c\/a\u003e\u003c\/p\u003e\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.
