Even if you aren't re-plating or re-sleeving, verifying your piston-to-wall clearance with a feeler gauge or bore gauge ensures you aren't running an engine that's too loose, which is the quickest way to break a skirt or lose compression.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003e\no    \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\u003e\no    \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\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/premium-motorcycle-chemicals-brake-fluid-bike-wash-coolant-chain-lubes\"\u003e2-Stroke Assembly Oil \u0026amp; Chemicals\u003c\/a\u003e\u003c\/p\u003e\n\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
