250+ miles to a tank.....can of worms opened

[FZ_Rich]

fill take to bottom of that tube thingy. ride 100 miles. fill tank to bottom of that tube thingy. use litres/gallons used to work out l/mpg. Useful this cos you can see what 100 miles of steady riding is to 100 miles of brisk riding.  Accelerating hard is what uses fuel and at 250 miles to a tank I suspect your not thrashing it away from the lights  etc
