Those are impressive looking results, Bo. I played around on a dyno with my bike this spring, 72 dyno pulls, 4 different intake lengths, 4 different exhaust lengths, numerous timing and jetting changes, tappet change with different radius, etc, etc, and all runs were within 5 hp, and only about 1-2 more than I have been running. Time for some drastic changes for me if I want to go faster!
