I am very new to this site, so I apologize if this is not posted in the proper place. If this is the case please let me know the proper place. With that said, I am in the process of restoring a 79 Yamaha RD 400 Daytona. All the powder coating is complete and ready to begin some asselmbly. In my infinite wisdom, I failed to ask the powder coaters to plug the holes the swing arm bolt goes through. Now there is not enough clearance to put the swing arm bolt through. I looked into it and I need a clearance of .020, I don't want to do this with a hand drill as this is a pretty important for handling. Should I take it to a machine shop? If so, anyone know of a shop you trust? Thank you in advance for any help and information.
