my bike was doing the same thing, I thought it was the fuel pump, so I replaced it. that did not help at all. so the next thing I replaced was the fuel pump relay. That did fix it for about 3 days and then it got hot again in the mid 90´s today and it did the same thing all over again. it was to the point that I would have to remove the gas cap and blow into the fuel tank to force fuel to the carbs to get it home. I don´t know how I can fix this problem, unless the new pump relay went bad right away
