Probably a stupid question, but I'll ask. My buddy has a 1999 883 Sportster Custom. He wanted to update his mirrors. He had the stock, old style, long stemmed, square HD mirrors. He got a pair of the newer style, short stemmed oval mirrors. Left side went on in a snap. Undo the bolt, take old mirror off, new mirror on. However, when we got to the right side, the mirror is attached to the right turn signal. OK, no problem. Took off the old mirror, put the new mirror on, and when we tried to tighten it down, it went so far, and then the right turn signal started to turn towards the floor. We tried adjusting the signal on the mount, added washers, etc., but no luck.......it seems like the mirror stem gets so far down into the mount and then pushes on the signal making it turn down to the floor........what could be the problem? It's gotta be something simple, but we just can't seem to figure it out.
