Precision machining of all rotating components resuts in a dramatic improvement of engine performance. Forces created by out of round parts are reduced allowing improved throttle response and smoother engine operation. Crankcase halves are squared to C/L of crankshaft. The TMM ICC engine is shown. Operation can be performed on ALL kart engines providing a significant performance gain.
