So I tried doing a sprocket and chain swap today with no luck. I couldn't get the front sprocket off. I had a friend pressing on the rear brake with the bike in neutral using a breaker bar to try and loosen the bolt with no luck. I made sure the washer was flush and not still flapped over the bolt and I doused the bolt with PB blaster and still no luck. I'm starting to worry the bolt is rusted on. Any suggestions would be greatly appreciated.
