The Boyesen RC2 Series Rad Valve is designed to increase power and throttle response performance in modified Yamaha Banshees. The RC2 Series Rad Valve is Boyesen's new performance intake system that replaces the power-robbing and restrictive stock reed valves on Yamaha Banshees from 1987 to 2006. The multi-stage reed petal system has been designed to increase throttle response and acceleration, while also broadening peak RPM horsepower output for a variety of stock and modified Yamaha Banshee setups. Dyno testing shows an immediate horsepower gain of anywhere from 5-10% through the majority of the Banshee's powerband. Sold as pair.
