If your hesitation occurs when the fuel is low and progressivly gets worse the lower it goe,s then I would say it is a fuel pump problem. I just had mine replaced at 45,000 miles. The hesitation on mine turned into bucking, but since the fuel pump was replacement I have had no such problem. I still have the slight hesitation when I try to get on it hard witrh low rpms. I'm not sure what this problem is. The tour almost acts like it is waiting for the secondaries to open before it is ready to go. If this is your problem I would love to also find out a solution.
