Keihin CV carburetors can now reap the benefits of the ThunderJet™.

ThunderJet™ adds that much needed high speed fuel circuit to the CV carb, allowing the existing fuel circuits to be more fine-tuned to specific power ranges, resulting in a more balanced fuel curve.

ThunderJet's patented third fuel circuit has a built-in air correction system that permanently solves the problem of poor mid-range and/or lean top-end performance.
