Moto Tassinari V303-FM Delta 3 Reed Valve System

  
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. V-Force 3i reed valve system with integrated intake boot available for noted 85cc models; 3i delivers a straight shot directly into engine cases for more balanced fuel/air distribution, newly designed reed stops for increased reed petal stability and a shorter reed cage for a noticeable performance increase due to lighter reed petals.

V-Force 4 is completely redesigned including: full length reed stops, reed tip area and wider cage increasing total air flow, and more aerodynamic cage shaping. When ordering replacement reeds, order one set per reed cage.
