Installing a Dynojet system in your Harley will give you increased horse power and a competitive advantage in close-course racing.

Fitting your Harley-Davidson motorcycle with a Dynojet will help you squeeze out extra horsepower, which is crucial in many races. However, be sure that you will use your motorcycle exclusively for racing, as Dynojet aftermarket kits are not designed for day-to-day driving or street use or on vehicles required to meet emissions standards. Installing a Dynojet will require some mechanical familiarity with your motorcycle. You should know where your carburetor is as well as how to remove it and how to adjust fuel flow.

Check for an increase in acceleration and power but also pay attention to how your Harley handles at regular driving speed.
