Description: VForce 4 Reed Valve SystemDescription The unique design of the VForce reed valve system features double the reed tip surface over a conventional reed valve design. This has two major benefits: 1) The reed petals only travel half the distance as a conventional reed valve design to get the same airflow. 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.STANDARD VFORCE REED VALVE FEATURESDouble the reed tip surface over a conventional reed valve designIncreased bottom end, stronger mid-range and longer top-endGreater efficiency due to reduced reed petal travelMore airflow means more horsepowerReduced reed petal wearScrew free design eliminates risk of screws going through motorScrew free design enables rapid reed petal changesNEW AND IMPROVED VFORCE4 FEATURESAll-new reed petal resin system, carbon fiber and lay-upPre-curved reed petal ensures better seal at tipWider reed cage for maximum airflowCombined reed tip area increased by 10.5% resulting in increased total air flowAirfoil shape added to cage tip to increase air velocity from outer portsLong reed stops added to progressively slow petal tip velocity, for increased petal durabilityReduced frontal area of central wing by 15.6% combined with a more aerodynamic shape WHAT'S INCLUDED WHEN I PURCHASE THE VFORCE4 REED VALVE SYSTEM?Moto Tassinari and VForce4 decals, detailed installation instructions, complete VForce4 reed valve system (including reed petals) and gasket.
