Owners of Harleys® fitted with Keihin CV carburetors can reap the benefits of the ThunderJet™. The ThunderJet™ adds that much needed high speed fuel circuit to the CV, allowing the existing fuel circuits to be more fine-tuned to specific power ranges, resulting in a more balanced fuel curve. By installing the ThunderJet™ and following the tuning instructions supplied, power increases will be felt throughout the entire (extended) RPM range, and flat spots can be eliminated. Installation of the ThunderJet™ in a CV carb requires minor machining to carb body and float bowl. A flat-backed air cleaner assembly (such as Zipper’s or the Screamin’ Eagle®) is required.
