Harley Carb Deluxe Tuners Kit

Complete carburetor performance in an all-inclusive kit. The CV Performance Deluxe Tuner's Kit w/EZ-Just for Harley-Davidson motorcycles is far more than a recalibration jetting kit. By way of CVP's custom designed needle, spring, and vortex emulsion tube, the complete kit will unleash the full potential of your Harley's stock carburetor. Also includes an assortment of jets, s/s hardware, gaskets, and full tuning instructions. The Deluxe kit is our most popular and includes the EZ-Just mixture screw.
