Allow me to vent a little, it's not a big deal but want to share my experience.
I've had the 40mph deceleration wobble on my 2005 Goldwing since I acquired it with 2,800 miles. I know that I am not supposed to remove my hands off the handle bars, but I discovered the minor shimmy AFTER reading about it on Goldwing forums. It is more common then thought, however owners just live with it and really don't worry much about it.
Was told that it was the DUNLOP tires, that I needed a fork Brace, that I needed new tapered head bearings ....
The gold wing currently has 7,800 miles
This past August, I replaced the wheels with chrome wheels and added new Bridgestone tires .... result .... reduced wobble
This past October, I added the SuperBrace ..... result .... reduced wobble a bit more
Sooooo both of these 2 above recommendations did NOT resolve my very,very, very minor wobble issue.
This leads me to believe that the head bearings need to be torqued a little tighter or replaced with tapered bearings, a 2-4 hour project. It is a very minor issue and it will NOT prevent me from keeping this bike, the Goldwing is by far the BEST motorcycle that I have owned in my life. I WILL always own a Goldwing. Looking back, I should have replaced or torqued the head bearings ... Live and learn.
