I own a 2007 Street Bob I bought used a few months ago. It came to me with forward controls. I notice down inside between the crankcase and the inner primary housing is the old mid shifter arm, just sticking up all alone. Looks kinda rusted in some areas. I got a flashlite and followed it down and it does in fact go into the primary inner housing. It looks like it has been pulled out some since the arm is right up against the crankcase housing. It doesn't move, just kinda stuck there. No oil leakage or anything like that. Is this normal ? There is a plug on the outside primary where the old mid shifter used to be. Should there be a plug on the inside ?
