Hi we bought a 2up 800 2008 have been out 3 times seemed to burn a lot of gas this last trip, was full tank when left and out 5 hrs and only one bar left,anyone out have one of these atv and what kind of gas milage are you getting and does anyone have any idea why we used so much thanks  

Your riding style, terrain, workload, and usage all factor in to gas milage on atv's. Other mechanical factors are air filter condition,(dirty or dust filled filters will reduce fm dramatically) spark plug condition, oil and differential fluid levels, and possibly elevation. I dont know the average fm for you particular atv, but these are common factors for all.
