Moto Tassinari V3126-873B-2 V-Force 3 Reed Valve System. When ordering replacement reeds, order one set per reed cage and confirm replacement reeds have the same number of petals as the set you are replacing. Snap-together cage uses symmetrical reed petals, eliminating the need for different "inner" and "outer" replacement petals. Reed tip shape accelerates air mixture, ensuring increased airflow for increased horsepower. Innovative design completely eliminates need for screws.
