Full to fumes is close to 5.5 US gal. If you look before you put in 5 gallons, it looks very dry in there. The rear area of the sump is where the last 1/2 gallon collect (logically).
I get the best mileage on the open roads, in warmer weather. I've gotten close to 55mpg when using 5th + 6th gears, and cruising at over 70mph. Stock ST2 gearing (15/42), opened airbox lid, and DUC perf. chip + DUC perf. exhaust.
