Thanks to all for your input. I was reading a long thread from last year and this guy had taken his to the dealer and the thread ended without any real conclusion or if tightening the bearings fixed the problem. I store my bike on a jack and the forks will swing side to side with no resistance. I am not in the habit of letting go of the handle bars but sometimes it becomes necessary to zip up a jacket or something. It's also alarming when you handle bars start to whip violently from side to side. I'm not sure just how bad this shimmy would get if I didn't stop it and don't intend to find out.

When I read the many threads on this problem it is evident that this is quite common with the Roadstar yet there is a very mixed response on how to fix it. And, maybe it can be caused by a cupped tire, loose bearings or handle bar mtd. windshields or a combination of things. I'll try taking the windshield off, simple enough, and go from there. The loose bearing issue seems like the most feasible cause to me. Having an extended warranty I may let my dealer examine it and see what they have to say. If and when I get the problem resolved, I'll post my finding. A basically new motorcycle with less than 3K miles shouldn't shake it's head...

Thanks again!!!
