Thanks to everyone here for your support and advice. I've held off taking any action just yet because the Triumph Regional Rep is returning to his office in Atlanta tomorrow (he was out of town last week when I first contacted Triumph last week)and I was told he would be contacting me. Who knows, maybe when the Dealer learns that I went to Triumph Corporate about this he'll wake up and pay attention. Then again maybe the dealership owner won't care.
One of the things I pointed out to the dealership owner when I spoke with him was that even if he had a new wheel on his parts shelf it would insane to mount it on the same machine in his service dept. He would have to send it somewhere else to have it mounted and hope that it mounted without damage or I'd be right back to where I started.
