Note: Thunder Mfg. makes cover inserts that allow you customize your Kuryakyn hypercharger! There are over 30 different sytles to choose from.

These inserts will only work with the Standard Hypercharger (not the Pro-R or other versions).

This kit contains an all chrome Hypercharger, mounting kit, and carburetor jetting necessary for a complete, sanitary installation. FI models should use a FI module like the Fi2000. FuelPak, etc.

Note: 9424 will fit carburated models, but the required jet kit will have to be purchased separately.

The interior shapes, especially the critical radius leading into the carb or throttle body, have been carefully designed. The outer cover incorporates an additional scoop to direct air into a high-flow, washable foam filter element that seats snugly in the end of the round K&N filter element. This filter assembly is one of the best flowing on the market and is capable of supplying enough air to even the highest output street motors. The fontal opening is huge and as with all Hyperchargers, the vacuum operated butterflies allow almost unrestricted airflow to the filter under high-load riding situations.

A mounting bracket/adaptor is a necessary item for mounting your choice of Thunder Air Kits to your Roadstar. The mounting bracket listed for the Roadstar will work for mounting all listed Thunder Air Kits. Thunder Manufacturing adaptors are designed for performance, and are easy to install and use. Note that when changing your airkit you will need to use an electronic fuel control system. If you already have a Powercommander you must remap it for the Thunder Airbox. Likewise if you have a Lightning FI or similar your settings will need to be adjusted accordingly.

Take advantage of this spectacular illusion, it is definitely the first of its kind. Throw the switch and the cover is instantly transformed. The smooth, mirror finished outer panel becomes a vortex of lights. The Infinity Streamliner can be installed on any standard body Hypercharger air cleaner quickly and easily in under an hour.
Seven Color L.E.D. technology operates in three stunning modes:

• Single color steady illumination.
• Single color flashing illumination with rheostat adjusted variable rate.
• Paint Mode: All lights, in unison, continuously fading into and out of each of the seven colors (red, lime, ice blue, sky blue, dark blue, purple, green). The rheostat can be used to adjust how quickly the lights fade from one to the next.

L.E.D. technology means there is no need to worry about draining your bike's battery (provided the battery is in good condition and the lights are not left for more than a couple hours). Get out there, the crowds are waiting!

Note: This is not a complete air kit! Must be used with Kuryakyn standard body Hypercharger air cleaner only!

Note: Will fit Vulcan 805 Classic.
