I don't know what we are talking about here. Just buy a new sprocket and slap it on. Shit happens and it was a mistake. Playing all these games no matter what you have to take the coves off to get to the key and they try to replace it or shave it down blah blah blah.

Nope. Buy a new one. I have multiple spares of these kicking around and someone near you does as well who would most likely just give it to you for free
