I found and article and supercharged two-strokes it seems a company has a patient on it , but im sure that dosent mean we cant do it ourselves, especially if the results they advertise are true. here is what theay say
Forced Induction Crankshafts
A patented modification for all two stroke applications!
Dirt Bikes, Snowmobiles, Personal Watercraft, ATV's, Chainsaws, and more!
The Parris Racing Concepts forced induction crankshaft modification works by cutting veins into the crank halves of the crankshaft. The veins are cut at specific angles into one crank half, and then a mirror image is cut into the other crank half. As the crankshaft spins, these veins pick up the fuel/oil mixture inside the crankcase. A process called flow dynamics then routes the fuel/oil mixture down the veins where it is directed at the transfer ports of the crankcase. When the engine enters its intake stroke, the extra fuel/oil mixture is pulled into the cylinder. The flow dynamics affect also atomizes the fuel/oil mixture in a way that allows a cleaner, more complete burn inside the combustion chamber.
The PRC forced induction crankshaft modification will work on any two stroke engine, i.e.; snowmobiles, dirt bikes, quads, jet skis, and even chainsaws. We modified a 2008 Suzuki RM250. It was found to gain 15.74% percent in HP and 18% in torque. Below is a comparative dyno showing the stock vs. mod results. The PRC modification produces enough torque that it has nearly eliminated the power band. A motor with a PRC, Inc. forced induction crankshaft pulls as hard all the way through the RPM range as a stock motor does once it hits its power band. Therefore, the modified machine gets to top speed faster than any stock machine currently available.
