That's pretty much the same as me. I get in the low mid 40s when hooning around, the best I've got has just topped 61 mpg on the A roads and this one was at a constant 80mph on the motorway, it gave about 55mpg. UK imperial of course.
No need, even I can work out that's about the size of a small coke can left. You're a braver man than meI’ve had my Katana down to 6km DTE.
Put 11.7 litres into a 12 litre tank (I’ll leave you imperial guys to do the conversion).
An illusion quickly shattered when you realise you forgot to turn the tap back to normal when you filled up last..............the bike stutters, you reach down to the fuel tap to flick into reserve but its already there.The "fuel reserve" thing is a throwback when motorcycles did not have trip odometers nor fuel gauges. In any case, the 'reserve' was nothing else than switching to a taller or shorter intake inside the tank. Sort of sucking through a shorter or longer straw from same container. An illusion really.
