I see a lot posted about sprocket changes (like theycallmebryan's 250r) and I was wondering if someone could explain how they work.

Switching the back sprocket out for a lower number of teeth can increase the fuel mileage by lowering rpms? At what point do the benefits cease? theycallmebryan has a 39 on the back, but you can buy 35's...

A small guide on this mod would be great!
