Oval Track Car Engine Packages

At Yoshimura, we have been building four-stroke race engines for over 50 years. Our reputation and success in the Road Racing world, is attributed to our passion and dedication to performance. We understand that your engine is the sum of many parts. If all the parts work in unison and in concert, large increases in reliable power occur. We do not simply throw in a big cam, bump up the compression, and create a time bomb - We build power at self-sustaining, balanced levels, because all the power in the world means nothing if you can't finish.

The Package below is just a small portion of what we can do for your GSX-R1000. Each is customizable to meet your performance needs and your budget. You can choose to have your current engine rebuilt or start with a fresh crate engine from Japan. Call Us Today and see how we can get you on the podium.
