Has anyone figured approximate MPG for these? I was just wondering how far a tank would take me if I were conservative on the throttle. I know there are a lot of factors but it might be nice to Have a thread for how many miles traveled and how much fuel used. I'm going to add a couple of one gallon Rotopax cans to mine and see how long a tank lasts on Easter weekend in the desert. Please post up any fuel consumption data here!
