3:23 and that was changed from 3:73. I've never gotten good gas mileage and Im stumped why? I was thinking the large (750) carb was the issue, hence why I swapped to the 600. But swapping to the smaller carb slightly improved it. Thinking about it if Im really easy on the throttle I can get maybe 120miles and that leaves me with a quarter tank of gas, but I dont know how accurate my gauge is so I dont push it. At 60mph, Im turning 2800rpm, at 70mph Im turning 3500rpm. I only have a 26.4" tire on the rear. So if I could get a taller tire that might help some also.
