HOT CAMS Racing Cam Stage 1 for Yamaha WR and YZ Models - Part Number 4035-1E

WE RACE ON THE TRACK, NOT THE DYNO! 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!

Enhance your Yamaha off-road motorcycle's performance with the HOT CAMS Racing Cam Stage 1 (Part Number 4035-1E). Designed specifically for models including the Yamaha WR and YZ series from 1998 to 2002, this high-performance camshaft delivers increased throttle response and improved engine efficiency. The innovative ITR technology features highly engineered opening ramps that provide a cleaner intake charge and a more complete combustion cycle, resulting in quicker throttle responses and better control. Whether you're racing or riding aggressively, this camshaft helps your engine react swiftly and smoothly, giving you the competitive edge on the trail or track. Installation is straightforward as it is compatible with stock valve springs and rockers in most applications, and some models include adjustable cam sprockets for precise tuning. This camshaft is engineered to maximize horsepower gains while maintaining reliable engine operation, making it an excellent upgrade for performance enthusiasts seeking to push their Yamaha off-road bike's limits. Please note, this product is intended for off-road use only and is not legal for use in pollution-controlled vehicles in California, though a waiver is available for race applications.
