How are you calculating your mileage? Is there a possibility that the odometer is not reading correctly?
If you have the capability, track your miles with GPS as closely as possible. Fill your tank full, drive the entire tank, and refill it to as exactly the same mark as closely as possible. Do this for three or four tanks and see what your average is.
This is - of course - after you have determined that there isn't something seriously mechanically wrong with the bike. You don't want to drive around that long with a gas leak somewhere.
What make is your bike?
