We have partnered with a custom cam manufacturer to bring you our own proprietary line of camshafts for the TW200.  This High RPM street oriented camshaft has much more duration than the stock cam, which allows it to make much more power and torque at high RPM when you guys are wringing these little motors out at 60 mph.  Due to increased lift and duration there is a natural loss of cylinder compression, so it is recommended to be used with a bigger bore or higher compression pistons, larger carburetor, advanced timing sprocket, and free-flow exhaust.  Install with 13-18 degrees of advance for best results (which is +1 tooth of advance on our advanced timing sprocket or +2 teeth on the stock sprocket).  Uses stock valve springs.  Works with stock or our High Performance Cylinder Head.
 
Cam specs: duration@ .050  252/250,  Valve lift  0.300",  LSA  108
