  1. best investment yet

    Posted by on

    This kit was by far my best investment for my Dyna yet. All the CVP videos made it easy to do and the adjustability I gained was amazing. My bike has never ran this good before.

  2. Excellent kit

    Posted by on

    Just received and installed a premium tuner kit in my 2002 Buell Cyclone with 9000 kilometers on the clock.
    I used some tips from a buell forum for my starting point. I selected my jets for my custom kit and added a couple of jets to have my angles covered.

    To my delight I nailed the tune with my second configuration. The needle and emulsion tube smoothed the changes from circuit to circuit as I explored my RPM ranges.

    With the modest amount of skill and experience I posess I was able to change the throttle response from a stuttering illness to a healthy growl with stamina and authority.

    With no gimmics or silly gizmos the product delivered all the potential of the resources in hand.

    Thanks for a fine product worth every penny I paid and more.

  3. Absolutely Amazing.... LOOK NO FURTHER

    Posted by on

    My 2003 Harley Nightrain only has 2300 miles on it. It obviously sat in the garage and really never ran good when I had installed the drag pipes and torque cones. It used to pop and cough but this year it wouldn't idle without the choke. Thinking it was my intake manifold, I replaced the seals and still ran like $hit. I purchased this kit, followed the easy instructions and oh my god.. it NEVER ran as good as it does now! The kit was amazing... I still cannot believe how good it sounds! I would highly recommend this kit to anyone that has a CV carb.. simply awesome! Thank you CV Performance!! You guys have done your homework. A+

  4. WOW, really made a huge improvement

    Posted by on

    Kit was easy to install (about 1 hr) and made a huge improvement in performance. If you are thinking about installing one just do it, you will not be disappointed.
