    Great product, you can feel the difference in the way the bike responds.

    Fit like a glove. Great throttle response. Very easy to install. I have stock pipes that have been gutted so jumped up two sizes from the stock jet to yield a perfectly running scoot. Price was decent. Fast shipping.

    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.

    Brian (San Francisco, CA)



    I recently bought the Cobra FI2000 ARB (California model) for my 2014 Yamaha Bolt R-spec. What a disappointment. Should have bought the non-legal fuel controller. It helped a little with throttle response but the backfiring was worse . The box says “virtually eliminates backfiring”. Not even. I lost 10-15 mpg for slightly better performance. Not worth it.

    Used on a KLR650. Power increase was nominal but fuel efficiency was increased and helped eliminate "popping" with my aftermarket Vance and Hines exhaust. Very user friendly with easy to follow instructions. You dont have to completely remove the carb for this upgrade but you really should so it can be properly cleaned at the same time.
