Performance Engine Kits

At Yoshimura, we have been building four-stroke racing engines for over 50 years. We understand that your engine is the sum of many parts. We do not simply throw a big cam in, pop up the compression, and create a time bomb. Depending on which engine modifications you choose, we can help build power at self-sustaining, balanced levels. If you want to win, you'll need the best engine performance you can get. Yoshimura offers three basic levels of engine performance upgrades, from port and polish to full-tilt race engines.
