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 remove it and adjust fuel flow.
Instructions
Installation
1. Select and purchase the Dynojet kit that fits your Harley Davidson model number and options. Read the enclosed manufacturer's instructions carefully. Set aside all parts so that they are within reach.
2. Secure your Harley-Davidson with the engine off. Put on your work gloves and safety glasses. Remove the carburetor float bowl. Remove any excess gasoline before beginning installation. Remove the main jet holder and replace with the Dynojet emulsion tube. Install the Dynojet main jet by screwing it onto the threads of the emulsion tube. Locate the side lift hole and use the drill bit provided in your Dynojet kit and your drill to enlarge the hole.
3. Install your Harley's e-clip into the Dynojet needle. Replace your stock slide spring with the Dynojet slide spring. Locate the fuel mixture plug, about 8 inches above the main jet. Turn the fuel mixture screw until it is past 3.5 and then untwist the fuel mixture screw until it is at exactly 3.5.
4. Replace the carburetor float bowl and reinstall the assembly into your Harley. Haul your motorcycle to a closed track for testing. Check for an increase in acceleration and power but also pay attention to how your Harley handles at regular driving speed. If your Harley struggles to maintain speed, you may need to install a slow jet later to control some of the performance enhancements of your Dynojet.
