Standard Hypercharger Kit with Chrome Trap Doors and Butterflies

Küryakyn offers complete Hypercharger Kits for most H-D® models equipped with stock or popular aftermarket carburetors.

Outstanding performance on stock or mildly modified engine up to 90 HP. With the addition of the Stinger Trap Door, P/N 8498, we have tested and proven the Hypercharger to support engines up to at least 130 HP.

Stock or touring applications where added performance is desired, but not paramount. Comfort and driver leg-room is a major factor.

Custom applications where matching or contrasting color trap door and butterflies are used as a styling accent.

Fits:  '90-'91 Big Twin with Stock Carb (Late Inlet). Also fits '84-'91 Evo Big Twin using High Perf Carbs like S&S/E or G, Mikuni, Screamin' Eagle, Rev Tech (Late Inlet) and Requires Adapter or Mount Kit (sold separately).
