  1. Best upgrade I've made to my bike

    Posted by on

    I ordered the premium tuner's kit, showed up in a couple of days, simple rebuild, and I've got a new bike. Just the Idle and mixture screws alone make tuning so much easier and managing performance on a frankenbike chopper so much simpler to manager. I would give this 10 stars if I could.

  2. Awesome performance gained

    Posted by on

    WOW! I watched the video and performed the tune-up. Swapped the 45 slow jet for the 48, replaced emulsion tube and 190 main jet with new from kit, drilled and removed mixture screw plug and set screw to 2-1/2 turns. The bike runs "orders of magnitude" better than it ever did. Excellent product, no more coughs/backfires. It's like getting a brand new bike. Great product!

  3. Absolute Best Carb Upgrade Available

    Posted by on

    I ordered the Premium Tuners kit, along with a new slide and pump diaphragm.
    3 days later parts received. I have a 1994 EVO that has never idled correctly. This year it decided not to idle at all. Started running so bad I could not ride. Completely disassembled and gave everything a good cleaning. The CVP parts are extremely well made and very easily installed. After 20 minutes rebuilding then another 30 minutes installing back on the bike I am amazed. I knew it would fix my problems but it's far beyond what I expected. Instant start ups, Idles as smooth as silk. My EVO new never idled like this. And the response is amazing. Only thing I needed that's not in the Tuners kit is a new bowl ring and pump O ring, picked up at dealer for $7.00. If you have a stock carb, carb problems, order the CVP Premium Tuner kit. Worth every penny and more. CV Performance is the only Way to go....

  4. Best bang for your buck.

    The product was easy to install, the instructions were simple to follow and the outcome was great. Did just what I hoped it would do solved hesitation and sluggishness. Very good product.
