now, because the engine is making more power at any given rpm, you could put a 41t sprocket on the rear (or a larger diameter tire) and lower your engine rpm's at any given mph, and the bike will still pull hard... you are already running 17-42; did i read that correctly?
Yes I have a 17-42 set up. I went to that because when I went to a lower profile tire, my rpms jumped up.
