I am noticing a problem with my starter on my '04. It seems that once in a while when I stall or shut the bike off and then try to restart it hesitates. It just gives one weak sounding chuck then stops. It is not spinning it just stops. The battery has a strong charge. All I have to do is roll the bike backwards a few inches while in gear so I can hear the starter gear spin a bit. Once I do that it fires right up. It has happened two or three times now. It seems like there is a dead spot or something. Anyone know for sure what the problem is? And what part do I replace??? Thanks for your help.
