  1. love affair

    Posted by on

    Thanks everyone at CVP. My 99 ultra classic was in dire need of some love and attention. She was coughing and spitting out of the carb and running like crap! I run the best fuel and oil and plugs in my scoot. But I never did much with the carb. It was time. I purchased the deluxe tuner kit . it was a fairly easy install. The tuner instructions was a bonus. She runs awsome!! I'm in love all over again.

  2. easy install, awesome results

    This kit was easy to install and worked better than expected. My dyna is a lot smoother and more enjoyable to ride. This kit is a no brainer.

  3. WOW!

    Just put this on a 97 883 Sportster. Had drag pipes on it and stock carb. Always stumbled on take off and popped. Low rpm was a chore as bike lugged and had no power. Put this on pretty straight forward and like the title says WOW! Can accelerate in any gear now , no lugging and bike pulls strong. Even tortured it by acclerating in 5th gear from 35 mph and still pulled strong

  4. Instant Gratification!!!

    The best upgrade I've made to my 03 Super Glide. I bought the bike used and someone had put Screaming Eagle pipes on it. Sounded good but had a stumble when you first rolled on the throttle. This kit corrected my stumble condition. The kit had everything I needed. Good, clear instructions on how to install the kit and tune the carb. The increase in power and response is very noticeable. If you want your bike to run like it should you need this kit! I also added an air cleaner upgrade to complete the stage 1 upgrade and gained even more power. If I had two more hands I'd give it 4 thumbs up!!!!
