Stupid design I'm tellin you turk, they should key the sproket to the shaft and no stupid bolt that is a cap. Here are some pictures ndfspd of my bushings and what they looked like after that stupid bolt was loose. Harley does not sell the bushings, it's a non repairable item they say. So eagle cut mine out and made some new ones. So eagle has the program set up for cutting the bushings now if you need them. I recommend adding a oil pressure gauge that way if you notice a couple psi difference then you'll know their is a problem. The oil pressure sensor on the bike now only goes on when their is only a couple psi so there is going to be damage when the light goes on, it's just a matter of how fast you can shut it down to limit the damage.
