Doubles the reed tip surface of a standard reed valve. On a VForce,with its less restrictive design, the petals only travel half thedistance, resulting in greater airflow through the entire RPMrange. Increased throttle response and horsepower, and typicallyincreased fuel economy. New snap together cage design eliminatesscrews. New patented reed tip shape that accelerates the airflow overthe reed tip, ensuring increased airflow for increased horsepower.
