On my way to CCR. Currently in ND. Bike has 210K. Have never done a cannerostomy. Have the classic signs of a block. First indication was vacuum buildup released when I stopped to get gas. Then the bike seemed to run out of fuel with about 30 miles still indicated. Next drama on this trip was crossing Ontario with 76 miles showing left on board. Fuel starvation. My on the road solution: fill up when I have 100 miles showing still on board and release pressure every so often by unscrewing the gas cap. In fact, I've taken to riding with the gas cap loose to let air in and no vacuum to build up. Anything else I can/need to do to keep her going and not damage anything more?
