Way to go. It's too bad that we have to go through this to get the dealer to stand behind a problem.
I don't know much about this kind of thing but Maybe the dealer has seen it a hundred times and is getting sick of paying for something that HD knows is a problem?
Seems weird the service Mgr. would tell you to call customer service knowing he would get a call from them on the matter, then turn around and fix it?
The dealer mad their $3-4K on your bike and if he expresses his dissatisfaction on fixing an issue that many have experienced, I would look for a better dealer myself. There are some out there.
