Kuryakyn 9420 - HYPERCHARGER CHR F/ROADSTAR

Since their introduction for H-D Models in 1992, The Hypercharger has been widely recognized as one of the most cost effective performance modifications available. When the demand arose for adaptation to the Metric Cruisers we expected similar performance increases, but never expected to see the gain common on these engines.
Check out the Dyno charts. Results were obtained from stock bikes with only accessory pipes, a Hypercharger, & simple carb re-jetting. The performance increase comes from simply letting the engine breathe. No decrease in longevity or drivability should be expected after normal, careful installation & proper jetting.
Aside from the desirable gains in performance, the Hypercharger is one of the most striking enhancements you can make to your bike. The cases are beautifully chromed with trap doors & butterflies available separately in a wide array of colors. 9420 ,'99-'09 Road Star 1600/1700 (ex. Warrior)
