Checked mpg on way home from meet, 27 mpg not too bad, loaded sidecar( for weight you have to have it) and fully loaded trailer. Ran 60 to 65 mph. Ran marine gas on first tank then Marathon on 2nd. Still have gas but how much?? Now if I can get that pesky gas guage working right. I never really know how much gas I have. I'm just using tripometer .I gas up at about 125 miles, still not on reserve yet. 77 and 82 are around 42 to 44 mpg. Just guest I have to pay to play. Jerry
