Replacing them with high-quality ProX valves during a top-end refresh prevents compression loss and ensures that your engine continues to start easily and make full power.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Should I also replace the valve springs?\u003c\/strong\u003e\u003cbr\u003eA: Yes, it is highly recommended to replace valve springs and seals whenever installing new valves. Proper spring tension is critical to prevent valve bounce and potential contact between the valve and piston at high RPMs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e After installing new valves, you MUST lap them lightly to the existing valve seat using a high-quality lapping compound. This ensures an air-tight seal for consistent performance. Always check your valve clearances after a short break-in period, as new valves can seat into the head slightly during their first few hours of operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/honda-crf150r-performance-upgrades-engine-mods-accessories-moto-house-mx\"\u003eHonda CRF150R Performance Upgrades\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/honda-4-stroke-dirt-bikes-performance-parts-accessories-moto-house-mx\"\u003eHonda 4-Stroke Performance Parts\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/mx-off-road-motorcycle-tools\"\u003eEssential Off-Road Motorcycle Tools\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
