The CV Performance Carb Mod Kit is designed to modify CV carburetors found on early Twin Cam Harley-Davidson models and Sportsters for improved fuel control during high-angle riding, including wheelies. This kit provides the components needed to help the carburetor maintain proper fueling when the motorcycle is tipped backward, making it a useful upgrade for stunt-inspired carbureted Harley builds. Note: This kit is intended to support proper carburetor modification and tuning. It will not fix an already poorly running motorcycle, incorrect installation, existing mechanical issues, or improper tuning. Final tuning will depend on your engine modifications, elevation, location, and carburetor setup. WATCH THE INSTALL VIDEO HERE!
