yeah, the way i did it, going down 3 teeth on the front primary pulley, was advertised as a 400 RPM increase at 60. but i also changed the tire size, but not by much, so i could have been at a different rpm at different speed. up to about 70-80 wasnt too bad. but, i rode across country at 85-95 (95 across west texas! love their speed limits out there!) and yes, it will buzz the **** out of you! lol!

Just plug in what kind of bike you got and change whatever gear you want.
All the other numbers (rpm, mph, etc) fill in themselves.

dude! thanks for posting! this thing is great! so, basically, i went cross country, on my 2004 flhrsi, at 80 mph and higher, and stayed over 4000 RPM !what a testament to harley longetivity! that bike now has 93,000 miles and is partially disassembled for an overhaul. (it wold have more miles, but i was deployed for over 44 months while i owned it, and i bought it new in july 04) but, that bike took a beating, and was still running hard when i took her apart.
