quick update on the sprocket...
I really dont notice a mpg difference. If there is one it seems small. I would say 1mpg less max. However, the fun factor out weighs everything. It shifts better, has more low end, and really makes the bike ride like it should have off the show room floor. Of course this is my perception. I wont be switching back to stock!!!
