Boyesen Rad Valve replacement reeds include petals, rev plates, and extra screws. They are designed to maintain the sharper throttle response and greater horsepower produced by Rad valves, while maintaining flow velocity and redirecting the intake charge to the intake ports. Featuring aero-optimized internal surfacing that corrects the problems associated with existing reed valve designs, they provide plenty of off-road torque, quicken throttle response, and ramp up horsepower throughout the rpm range.
