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.
The VForce is a reed valve system that completely replaces your stock reed valve assembly. Snap together cage design with symmetric reed petals. Reed tip and shape accelerates the air mixture over the reed tips. More factory teams depend on VForce technology than all the competition combined. Greater flow results in a crisp throttle response and harder acceleration.

If your tracking information states'Delivered', but you have not yet received your package you should. A doorstep, front porch, back porch, garage, window, etc.(A well-meaning neighbor might have taken your package inside their house for safekeeping or for protection against the weather). Wait 24 hours (in rare cases tracking may say delivered up to 24 hours prior to arrival). We understand that such delays can be very inconvenient when they occur, but we do not have any influence over such situations.
