The simple premise of the VForce3 reed valve system is to increase engine power and throttle response by increasing the efficiency over a conventional reed valve design.

By hodgkins , October 18, in Kawasaki 2 Stroke. I have carbon fiber ones in my 01 now but I can't remember what kind. More than likely they are Boyesen single stage. Ultimately I would like a set that provide the best low end. I run Boyesen Carbon Pros, because I like the response they give in the meat of the midrange, and they don't flutter at high rpms like stock resin reeds. For low-end, you want the three-stage Power Reeds, but they do take some substantial jetting changes to run correctly. The V-Force is mostly marketing hype. It will produce some improvement in throttle response, but it will not produce any significant increase in power production levels. The Rad Valve will increase actual power ouput, across nearly the entire rev range. So where do you imagine the missing center divider went when it broke off? If you guessed that it went through the owner's engine, with predictable results, give yourself a cookie.

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.

The recent purchase of my KX came with new in box VForce3 reeds. I also like to clean and verify carburetor jetting on any motorcycle that I purchase, especially 2 strokes. The broken petal is on top left. I performed a compression test when I first purchased this KX, and it came in at psi. After the VForce reed install, I retested compression and it shot up to psi. After reading some forums posts, this model should see anywhere from psi with a fresh top end. Remember, the reeds act like a one way check valve, only letting air in the engine. The broken reed petal was allowing some of the air escape back where it came from rather than into the combustion chamber, hence the lower compression reading.

It points slightly to the left side of the crankcase, due to the constraints of packaging the air box, carb, shock, etc into such a compact space. The Rad Valve, on the other hand, does significantly alter both the volume and velocity of the air flow into the engine, thereby increasing power. Are there any special tricks to the jetting with the Rad Valve, I experimented with jetting around the V Force but ended up with no change over the std reed block. Kawiguy Posted October 18, This is what can happen to a V-Force: So where do you imagine the missing center divider went when it broke off? What reeds do you run on your KX? The Rad Valve will increase actual power ouput, across nearly the entire rev range. Prev 1 2 Next Page 1 of 2. By hodgkins , October 18, in Kawasaki 2 Stroke. Mastercard and Visa are the two largest companies of credit card payments. I run V force and felt a definite improvement in torque and throttle response on both KX and CR

The unique design of the VForce reed valve system features double the reed tip surface over a conventional reed valve design. Sign in with Twitter. But because it changes the air flow, it also changes the jetting. The Rad Valve is specifically designed to straighten and direct the air flow for even distribution into the crankcase, to improve crankcase filling. The simple premise of the VForce3 reed valve system is to increase engine power and throttle response by increasing the efficiency over a conventional reed valve design. Kawiguy Posted October 18, This is especially noticeable on the track.
