I am going on a long ride this weekend (80 miles) and some of the guys going with me only have 2.6 gallon tanks. My bike has a 3.2 gallon tank. Last year when we did this trip, the guys that had the 2.6 gallon tanks did not finish the trip because they ran out of gas. So this time we are going to take some extra gas with us. Are plan is to take some 20oz. bottles and fill them up and duct tape them to the front fender. Does anyone see a problem with this, or does anyone have any suggestions? We were also debating on filling them up so there was no air in the bottle. Because if you leave air in the bottle the gas will move around and expand more.
