We recommend completing several heat cycles—allowing the engine to reach operating temperature and cool down fully—before moving to light, variable-load riding for the first hour to ensure the rings seat correctly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When performing a top-end rebuild on these high-revving 65cc engines, always check your power valve assembly for carbon buildup while the cylinder is off. Cleaning the power valve mechanism ensures it operates smoothly, which is critical for maintaining bottom-end power. Additionally, always lubricate the new piston and cylinder walls with a high-quality 2-stroke oil during installation to prevent scoring on the first start.\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 \u0026amp; Upgrades\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 \u0026amp; Upgrades\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
