This thread brings back memories of a personal experience with trying to get a warranty issue (that dealt with paint) properly addressed at a truck dealership. Fortunately a friend who owns a body shop told me how to word my questions. Beyond that, on any issue like this, if you aren't getting results, start writing letters and making phone calls. "The squeaky wheel gets the grease." And since you're right, it should eventually payoff as it apparently has.
I took a quick look at the Lemon Law, but see in my own state of Pennsylvania that motorcycles are not covered. In other states the law applies to most vehicles under 12 months/12,000 miles, and usually, but not always, relates to what happens after 3 unsuccessful repair attempts. This sure seems like a lemon issue!
This brings up some new questions....
Does the dealership tick repair take care of the ticking issue forever, or does it often reappear?
If the repair takes care of the tick forever, what fix are the dealers applying that hasn't yet made it back to the assembly line? They must be using different parts(?)
