I get pretty crappy gas mileage.... light comes on anywhere between 90 and 100 miles when I'm commuting. And if I'm traveling I get an extra 20, but track mileage is usually around... oh I dunno 70? :O
yeah, my normal every day riding the light will come on around 110 and on the track it'll come on around 65 or so. I ride mine like I stole it though, the only time it's ever been ridden easy was during the break in period.
I normally get about 45-50 mpg, but at the Isle of man it dropped to 38 mpg, my old GSR (2006 model) never got above 40 mpg, proof that fuel injection & a catalytic convertor is less efficient and raping the planet.
I have a 05 636, i am only getting about 22mpg! my gas light comes on right around 90mpg. i have installed new spark plugs, new k&n air filter and a power commander. Before i installed anything i was getting the same mpg. I do have an aftermarket slip on akrapovik exhaust on the bike. But it just doesn't make sense that i am getting such shitty mpg. Any ideas?
