VForce 3 System – Yamaha Three Cylinder Moto Tassinari Factory Shop

NOTE: Fits All Yamaha triple cylinder except XLT/GPR 1200 Powervalve Motor & 1300 Motor.

The VForce3 Reed Valve System incorporates features you won’t find with other system on the market. With such features as twice the reed tip surface, radius cage surface, snap-together construction, proprietary carbon fiber recipes and more. By doubling the reed tip surface the petals now only need to open half as far to have the same flow as a stock style cage. This is a significant advantage when you factor in that a reed petal opens and closes 133 times per second at 8,000 rpm. The petals are only traveling half the distance of a stock style cage, so now fatigue to the petal has been greatly reduced, increasing petal life. This design also enables the valve to drastically improve the entire powerband with a significant boost in the bottom and mid. Instant throttle response is an understatement! The petals now sit on a radius surface to create a pre-loading effect that improves an already snappy acceleration. Our new cage design now allows the reed petal tips to be recessed into the cage itself. This allows for a cushioning of the reed tips and also discourages the possibility of any back-flow.

SYMMETRICAL REED PETALS:
The VForce3 now uses symmetrical reed petals for both the inner and outer reed petals. No longer will you need to be concerned with having both inner and outer reed petals. VForce 3 Reed Blocks utilize Part# 3P794A reed petals (4 fingers per reed petal).

SNAP-TOGETHER CONSTRUCTION:
The VForce3 Reed Valve System incorporates the industrys first and only patented snap together reed valve design. The entire assembly is completely screw free, meaning that when reed petals need changing the job is now literally a SNAP.

CUSTOM AIR-GUIDES:
Custom air guides specific to each individual application ensure the maximum airflow and performance benefits of the VForce3 reed valve system in your pwc.

PROPRIETARY CARBON LAY-UP:
Moto Tassinari continues to test and develop new recipes for our carbon fiber used in the VForce3 Reed Valve system. In fact Moto Tassinari specs our own exclusive recipes for all the carbon fiber we use, you can be assured you will never get generic carbon fiber designed for somebody and something else, when you buy VForce.

TWICE THE REED TIP SURFACE:
The unique and proven design of the VForce3 Reed Valve System doubles the available reed tip surface over a conventional reed valve design. By doubling the effective reed tip surface it enables the engine to get more air with less effort. The number one rule in two-stroke motor modification is More Air = More Horsepower.

AIRFOIL TECHNOLOGY:
The new reed cage design on the VForce3 Reed Valve system incorporates airfoil shaped (flat on bottom/curved on top) reed tip surfaces which in turn increases the velocity of the fuel/air mixture as it passes through and over, creating the optimum fuel atomization.
