2 Because the reed petals only need to travel half the distance of that on a conventional reed valve design, there is a greater chance of them being fully opened as well as a better chance of sealing when they are "closed". A reed petal never truly "closes" in a classic sense, as it is always in movement. Consider this, an engine operating at 8,000 RPM results in a reed petal opening and closing 133 times in one second. This fact, sheds light on another VForce advantage. Since the petals are only traveling half the distance, they generally last longer are they receive less wear than the reed petals on a conventional reed valve design.Features: Double the reed tip surface over a conventional reed valve design Increased bottom end, stronger mid-range and longer top-end Greater efficiency due to reduced reed petal travel More airflow means more horsepower Reduced reed petal wear Screw free design eliminates risk of screws going through motor Screw free design enables super quick reed petal changes Kit Includes: Moto Tassinari product line brochure Moto Tassinari and VForce decals Detailed installation instructions VForce3 reed valve system consisting of three complete reed valves (including reed petals) and gaskets.
