Performance: On development using the in-house Dyno we achieved a horsepower increase of 6 with the increase right through the range. Torque was increased at the right spots and there are significant gains right from the bottom through the mid-range. On the road is where the gains are truly appreciated. The throttle response through mid-range is instant and smooth and feels like a lot more then a 6Hp increase. Throttle roll on is also smooth and responsive and has removed any hesitation for the big twin to open up.
