I installed a UNI filter and a juice box pro into the 2010 Fjr. Then I took it to Nels at 2 wheel dyno works and had him build a custom map for the bike. I told Nels that I wanted the bike smooth and was not looking for max power. The bike is now super smooth. No more lean or rich spots in the bikes fuel delivery. The install of the juice box pro and the filter takes about 1:20. Nels spent about a hour to build a custom map for the bike. While watching the A/F on the dyno it was amazing the difference the custom map did to the fueling.
