geez, that's over 200 miles per tanks. I am lucky to get it above 100 before the reserve kicks in. I just changed the air filter, oil filter, and engine oil, and mileage improved slightly. but I never get that sort of number. I mostly run the bike at 4th gear when cruising. I put it in 5th/6th in 2 miles stretch. and 3rd gear through out small section of curves. I punch it sometimes 60-70% throttle, but that should affect only little. all my riding is in town with plenty of signals. My front rotor(s) might be warped, but asides from that, I have no idea why my cbr is sucking more gas, I run 89. everything seems stock, so I have no way of telling if the sprockets have been changed, but probably isn't.
