If your current cylinder is damaged or out of spec, you will need to purchase a replacement sleeve separately.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e Always check your ring end gap before final assembly. Even with a high-quality kit like this, verifying that the gap is within the manufacturer's specified tolerance is the best insurance policy against premature seizure or loss of compression. Also, never force the circlips—ensure they are fully seated in the groove to prevent catastrophic engine failure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-yz250-and-yz250x-performance-parts-collection-at-moto-house-mx\"\u003eYamaha YZ250 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\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
