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.STANDARD VFORCE REED VALVE 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. Screw free design eliminates risk of screws going through motor. Screw free design enables rapid reed petal changes.
NEW AND IMPROVED VFORCE4 FEATURES. All-new reed petal resin system, carbon fiber and lay-up. Pre-curved reed petal ensures better seal at tip. Wider reed cage for maximum airflow.Combined reed tip area increased by 10.5% resulting in increased total air flow. Airfoil shape added to cage tip to increase air velocity from outer ports.
Long reed stops added to progressively slow petal tip velocity, for increased petal durability. Reduced frontal area of central wing by 15.6% combined with a more aerodynamic shape. Moto Tassinari and VForce4 decals, detailed installation instructions, complete VForce4 reed valve system (including reed petals) and gasket.
