We recommend checking your spark plug color after your first few warm-up laps.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I replace just the carbon fiber reed pedals when they eventually wear out?\u003c\/strong\u003e\u003cbr\u003e\nA: Absolutely. You do not need to replace the entire aluminum assembly. Boyesen offers application-specific replacement dual-stage reed pedals that install directly onto this RAD-30C body framework when the old ones begin to fatigue.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When installing your new Boyesen RAD valve, make sure the engine case mating surface is completely clean and clear of old gasket material or debris. Always use a torque wrench to tighten the mounting bolts in an alternating cross-pattern. Uneven tightening can distort the rubber intake boot flange, creating a dangerous lean air leak that could cause catastrophic two-stroke engine damage.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003e\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-yz85-performance-parts-and-accessories-moto-house-mx\"\u003eYamaha YZ85 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\/mx-off-road-motorcycle-tools\"\u003eMotorcycle Tools\u003c\/a\u003e\u003c\/p\u003e\n\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
