  1. Running Strong

    Posted by on

    After years of hard starts, popping and deceleration back fires, it's all gone.

    Starts with out choke right away, great acceleration .

  2. Complete jet kit

    Posted by on

    This kit was well thought out. They include everything you need to re-jet your carb. They even provide new hex screws to replace the Phillips screws on the bottom of the carb so you don't have to remove the entire carb to change the jets in the future. The instructions are thorough and well written. The addition of the thumb screw to adjust the mixture is a great idea. My bike runs much smoother now and I'm not fouling plugs anymore.

  3. cv carb revival

    This brought my sportster to life in the lower ranges it was always great on the top but in the lower range it coughed and back fired. That's all gone now, just excellent pick up can't say enough about this Kit, and its all good.

  4. Kit came fast and was easy to install

    Posted by on

    So I got the deluxe kit for my 1996 FLHT and it's 80" Evo and installed it without a hitch! Thank you guys very much for also giving me the jets I requested in the comments section of my order. This upgrade fit my brand new carb and was ridiculously easy to install. It all appears to be high quality and excellent workmanship. I however have not had the opportunity to test it yet due to 6 weeks being not enough time for a machine shop to bore out a set of cylinders. Can update later one day when I actually get the opportunity to ride again.
