   Abstract: For meeting the demand in special market for high performance and high speed motorcycle engines, the engine was simulated by the advanced simulation software BOOST to explore the main factors that influences the engine performance at high speed. The intake system was optimized to have a better engine performance at high speed. The bench test shows the expectation that the high speed performance increases 11% and the medium speed performance does not change.
