How to Install a Kuryakyn Hypercharger

Updated February 21, 2017

The Kuryakyn Hypercharger, available for both metric and American motorcycles, adds not only a bit of flashy chrome to the engine, but improved performance, as well. As part of installation, you may wish to re-jet your carbs to make use of the increased air flow, and if you have not already done so, a high-flow exhaust will cap the package off with a noticeable increase in power, not to mention the extra bark to go along with the bite.

  1. Remove the stock air cleaner assembly of your motorcycle using a wrench and set aside. You may wish to box it up for the time being until you are certain that the Hypercharger will fit your needs.

  2. Turn off the fuel cut-off switch, then remove the vacuum line from the carburettor.

  3. Cut a two-inch length of 3/8-inch vacuum hose and attach the "t" shaped fitting supplied with the kit to the vacuum line, then reattach the spliced line to the carburettor.

  4. Remove the Hypercharger's round trap door using an Allen wrench, and insert three cap screws included with the kit into the mounting holes from the inside. Do not put a bolt through the bolt hole now in the 10 o'clock position.

  5. Place the Hypercharger over the included spacer ring and support bracket, then gently tighten the bolts which hold the intake in place.

  6. Replace the trap door and the intake gasket.

  7. Reattach the vacuum hose into the inlet located on the back of the Hypercharger unit. Run the remaining section of hose to the breather tube on the carburettor, then to the ground. Route the line through tight places with needle nose pliers.

  8. Tip

    The instructions herein are applicable only to carburetted motorcycles; fuel injected motorcycles require an entirely different approach. Re-jetting the carbs of your motorcycle will result in the best performance from the Kuryakyn Hypercharger.
