Most camshaft designs are developed only on a dyno. Good camshaft designs not only increase power, they also improve throttle response. However, more power and better throttle response is a difficult design problem. Hotcams’ ITR technology solved this dilemma through highly engineered opening ramps not found on other cams. Using ITR technology, the critical ramp area is designed to give your engine a cleaner intake charge and a more efficient combustion cycle, making your engine more responsive at all throttle openings and giving the rider better feel and control of the engine! You will notice the difference!\n\u003cp\u003eUpgrade the performance and throttle response of your Yamaha YFM660R Raptor with the Hot Cams Stage 2 Racing Camshaft, manufacturer part number 4005-2 and vendor part number 68-2067. Designed for high-performance racing applications, this camshaft uses Hot Cams Improved Throttle Response (ITR) technology to optimize valve opening ramps and improve the engine’s intake charge and combustion efficiency.\u003c\/p\u003e\u003cp\u003eThe Stage 2 profile is engineered to deliver stronger power while maintaining crisp throttle response across the operating range. The result is improved engine feel, better rider control, and more immediate response at different throttle openings. This Hot Cams camshaft is designed to use stock valve springs and rockers in most applications, helping simplify installation and compatibility. No camshaft core is required, and adjustable cam sprockets are supplied with some applications.\u003c\/p\u003e\u003cp\u003eThis racing camshaft fits 2001 through 2005 Yamaha YFM660R Raptor models. Confirm engine configuration and application requirements before installation. The Hot Cams Stage 2 Racing Camshaft is intended for competition use and is not legal for use in California on pollution-controlled vehicles; race-use operation may require an applicable waiver.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-performance Stage 2 racing camshaft\u003c\/li\u003e\n\u003cli\u003eHot Cams Improved Throttle Response (ITR) technology\u003c\/li\u003e\n\u003cli\u003eDesigned to improve engine power and throttle response\u003c\/li\u003e\n\u003cli\u003eEngineered opening ramps support a cleaner intake charge and efficient combustion\u003c\/li\u003e\n\u003cli\u003eDesigned for use with stock valve springs and rockers in most applications\u003c\/li\u003e\n\u003cli\u003eNo camshaft core required\u003c\/li\u003e\n\u003cli\u003eAdjustable cam sprockets supplied with some models\u003c\/li\u003e\n\u003cli\u003eFits 2001-2005 Yamaha YFM660R Raptor\u003c\/li\u003e\n\u003cli\u003eManufacturer part number: 4005-2\u003c\/li\u003e\n\u003cli\u003eVendor part number: 68-2067\u003c\/li\u003e\n\u003cli\u003eRace use only in California on applicable pollution-controlled vehicles\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\n2001 Yamaha YFM660R Raptor\u003cbr\u003e\n2002 Yamaha YFM660R Raptor\u003cbr\u003e\n2003 Yamaha YFM660R Raptor\u003cbr\u003e\n2004 Yamaha YFM660R Raptor\u003cbr\u003e\n2005 Yamaha YFM660R Raptor","brand":"HOT CAMS","offers":[{"title":"Default Title","offer_id":67555833118955,"sku":"68-2067","price":358.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/222f-5a5e4939948f7.jpg?v=1790745201","url":"https:\/\/ctracingservices.com\/products\/hot-cams-stage-2-racing-camshaft-4005-2-for-yamaha-yfm660r-raptor","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
