CV Performance Tuners Kit Instructions

Harley CV carburetor

In addition to the detailed instructions included with the CV Performance Tuners Kit, the following video instructions are provided to help guide the installer. Before beginning the tuning process we recommend installing a new set of spark plugs.

Different than a carburetor rebuild, the installation of a tuners kit brings out the true performance of your Harley CV carburetor.
Video Part 1 goes over the dissassembly of your Harley CV carburetor, parts identification, and installation of the new parts found in the Tuners Kit.

Video Part 2 covers the mixture screw and fine tuning required to finish the installation. We also install an EZ-Just Mixture Screw to make tuning simple.


Note: Main jets supplied by CVP are sized to original OE specifications from H-D and Keihin for the Harley CV carb. If using with a DynoJet® or other aftermarket jet holders (emulsion tube) the threads will not match. Always use an OE holder/tube or the CVP emulsion tube with CVP brand jets, also found in our tuner kits.
