This bike had 1064 miles on it. Power comes on at 7000 rpm and continues to carry up to the soft limiter (well below the 16500 redline). The stock fuel curve was well within specs and a PC3 is not required.
Horsepower gains are limited because of the welded on “boom-box” chamber. Gains of 1 - 2 horsepower are all that can be expected. Styling and sound are significantly improved for a very small investment.
