Have you had any other problems with your T-Bird that you care to share, I am very interested in any information on your T-Bird. One thing that I am trying to determine if some of the problems I am experiencing could be due to my dealers service of the bike. I´m not confident in some of the work they have done to the bike. My handle bars did not shimmy until they changed my front tire. When they called me to let me know the bike was ready for pickup they said they had taken it out for a test ride and everything checked out. Yet I went less than a mile and when I hit between 25 to 40 mph my front end started to shimmy pretty bad, no way anyone could have missed it.
