    Fp3

    Installed FP3 with power duals and monster rounds on a 2015 CVO Road Glide Ultra. After some time on phone with techs we got it tuned in right. Big difference from stock, and sounds great. Simple install.

    Carb Kit

    Great price and everything you need for the stock carb rebuild. Nice clean new parts that are strong and seal well. I used this kit on a Yamaha Big Bear 350 4x4, and it really helped bring it back to life.

    gsxr killer

    Now my '14 CBR1000RR is a killer. Im using preset map 1 cause I couldn't download software. She ready now! A few broken fingernails removing all the connectors. Other that it's a good mod.

    Cobra FI2000

    Did the stage 1 upgrade on my 2007 Night Rod Special which consisted of exhaust, hi-flo air filter and fuel manager. Installation was a bit challenging considering the front and rear fuel injector connections are directly in between the jugs. A set needle nose pliers will speed up the process. Factory settings from Cobra are preset at 2-2-2. Still ran lean so I bumped all 3 pots to 4-4-4. No more lean condition, bike runs/performs fine. Decent product!
