After an hour or so ride on the times I stop for gas and start it turns over slow and kinda makes a clunk like noise. So far it has always started. Only does it when I just shut off for a few minutes( I would say 5-10 minutes) If I stop to eat or somewhere where I leave it off 1/2 hour or so no problem. I bought my Fatboy new and only have 6304 miles on it. I usually ride it at least once a week for an hour or so.
