Fuel: unleaded 87 pump octane
Fuel economy: average 75.6 mpg until last fillup that was 66 mpg with exclusive city driving.
Top speed thus far: 70 mph
Only thing I can suggest to make this bike go any faster is to loose weight and tuck yourself like you are on a crotch rocket, loose the windshield and keep your knees in. Use non-ethanol fuel. add roots blower or some other forced induction. However without major modifications to the engine you will not peak 85mph I only ever achieved 83 mph down hill drafting a truck on the interstate tucked in with non ethanol fuel, no windscreen and fresh tires.

P.s. I weight 245, not picking on you just saying that it is over average intended rider spec. :rawk:

I have went from 250 to 1200 and i love every bit of it. I lost about 12 mpg but with performance and weight that happens... my bike pushes 95 hp form factory that is alot more than a gz and it still wont peak 130mph at any configuration without major modifications. 1984 Gl1200 Goldwing Custom(Naked)
