Before firing the newly built motor up for the first time, perform a basic cooling system pressure check and an engine leak-down test if you have the tools. Verifying that the crankcase holds pressure prevents an accidental lean condition from an air leak, which can instantly ruin a brand-new piston and crank assembly during heat cycles.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/ktm-65-sx-performance-upgrades-engine-mods-accessories-moto-house-mx\"\u003eKTM 65 SX Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/husqvarna-tc-65-performance-upgrades-engine-mods-accessories-moto-house-mx\"\u003eHusqvarna TC 65 Performance Parts\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/gas-gas-mc-65-performance-upgrades-engine-mods-accessories-moto-house-mx\"\u003eGas Gas MC 65 Performance Parts\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
