The amount of fuel used depend on your riding style, if you
always wack all the way, you used more petrol say 20km/litre. If
you ride slowly, never exceed 5k rpm and during down slope you
don't throttle and let gravity do it's job, getting 50km/litre is
not a problem at all. Your carburator got 3 types of jet settings,
if you go very high rpm, it can suck your petrol tank dry in a
matter of minutes.
