sprokets and fuel mapping?

what exactly does changing sprockets do, and what does fuel mapping do?

changing sprockets changes the gearing on a bike, add teeth to the back or remove them from the front to lower the gearing (more grunt) , add teeth to the front and remove them from the rear raises the gearing, more top end no low end, fuel mapping changes the air/ fuel ratio amoung other things in fuel injected bikes (kinda like changing jets and needles in a carburater)

Drewpy is right on. A common mod is to go -1 in the front and +2 in the back for a little more low end pop.

You usually end up messing with the fuel mapping if you change the air box from stock, or replace the stock exhaust with a full aftermarket systems. Both of those Mods affect the air/fuel ratios so you need to refine the map to maximize the effects of your modifications.

I suppose one can optimize fuel mapping on stock exhaust, stock filter and probably intake restrictor plate still in place. Stock gearing and Fuel mapping from the factory is there to make the bike pass emission test and noise test, which doesn't mean that your bike is running at optimum setting.

However, most people don't change the fuel mapping unless they do things to really change the bike's breathing such as freer flowing air filter, removing air intake restrictor plate, catalytic converter removal, exhaust system replacement, etc.
