well bike has full monty, blue flame can, ignition advancer, 2 teeth extra on rear sprocket and is allways running with a 46 ltr topbox and even though i have lost a big chunk of wieght i am still 20st so close to allways 2 up.
add in to that i allways ride to have fun even when commuting thats why i get those figures
though i do tend to surf the tourqe so its rare i go over 6-7k revs, but its allways full throtle to get there.
as my local dealer jokes each time it go's in for work "do you want me to swap the throtle for a switch yet" as its allways ON or OFF
but im fairly happy with about 40mpg on a 1 ltr bike thats heavy and fast
if i really wanted better fuel mpg i would ride a 600 or a 400 moped
