Yes, my gas gauge isn’t near accurate, a problem I hope Kawasaki will address. After filling a couple of times, here are my observations. The tank stretches from under the passenger seat to under the driver seat ( makes me want to practice fast exits). It is shallow and wide. If you insert the gas nozzle into it like you would in a truck, it will not get full. Pull it out of the filler hole a bit and hold it while fueling. This shallow, wide tank will cause misreads when the vehicle is off camber. It can also cause starting problems when parked off camber. Also, when down to one bar, and that one bar starts blinking, you have 2 1/2 gallons left (According to the manual). Based on my last 85 mile ride, this is an on and off phenomena depending on your camber. 85 miles driven, blinking last bar as I pulled into a gas station, 6 1/2 gallons to fill up. Thus, around 3 gallons left. Come on Kawasaki, is this right? So my best guess is around 11 mpg, mostly in high gear, some low 4 w climbs in Mesquite NV.
