We appreciate the e-mail and you have done NOTHING wrong with your installation. Noram, who makes this clutch made a change to the thickness of the hub without notifying us. This change impacts the fastener engagement so you are spot on in your findings. We have a bulletin out to our dealers and have updated all of our inventories with a longer bolt to adjust for this manufacturing change. It sounds like we need to help you out and we would be more than happy to send you a new fastener kit.
