Well, I appreciate all the responses................but I still don't get it.
Parts in stock? In my experience most dealers don't stock anything much beyond oil filters and spark plugs even for the most current bikes.
Availability of parts? Except for a few things, Suzuki still supports my B4 pretty well. What is not available from the OEM, I can usually find in the aftermarket or on ebay.
Can of worms? Like I said in my original post, my bike is very low mileage and virtually flawless. Most two year old sportbikes are not in the condition that mine is. AND, I'm a knowledgeable owner who could assist with finding parts or providing info (I own my own copy of the factory service manual as well as the microfiche and a complete parts cross reference).
As to me abandoning the bike in place? Get real. I'd just as soon abandon my wife and kids. If I ask for something to be fixed, I expect to pay a reasonable price for the service ($90 bench rate notwithstanding) and that price has nothing to do with the "value" of the motorcycle.
Current technology? While most street bikes don't have carbs anymore, dirt bikes do, so the dealer should not be totally unfamiliar. Beyond the carbs, my B4 doesn't differ significantly from most of what's on the dealer's floor. So like i said, I still don't get it. In this economy, you'd think they would be begging to take my money rather than turning me away without even looking at the bike. I can tell you one thing for sure, I will NEVER buy a bike from a dealer with this policy. The local BMW and Ducati dealerships will work on any BMW or Duc that rolls through the door.
As to independents, I'm open to suggestion, but in my neck of the woods if your bike isn't a 45 degree v-twin painted black and orange you're pretty much screwed.
