    I ordered the Premium Kit, and the inlet elbow. First time tearing into a CV carb, was a bit nervous. No need to be! Between the introduction sheets that came with the kit, and the online videos...........easy-peasy. I took my time, and it was done in less than two hours, if you have been into a CV before, I could see this done in a half hour. Set it up per instructions, fired right up. Finally got to take it out yesterday and start really dialing it in. With the EZ-Just screw, no problem. Snappy throttle response, definitely feels like more power, can't wait to really put it through the paces. Thanks so much CV Performance!

    Awesome product!

    Quality product. Fast shipping. And made a noticeable difference even before fine tuning. Will do business again.

    I've used 3 of these kits (and the low profile accelerator pump nozzles) on 3 different XL's, and they're almost flawless. Easy install, reasonable price, and VERY accurate jet sizes. As a former H-D tech, I usually don't use the instructions; but, they are relatively easy to understand. The idle adjust is great. The mixture thumbscrew is incredibly
