Thanks for the info Tony! I will check the steering head bearings.
Anyone else have a issue like what I described if it is not the bearings?
Scared checking in. I have had, what you describe, on my Ultra since new. I always took if for a combination of the Touring characteristics and the abysmal surface conditions of the English roads.
It can be bloody scary when it happpens though as it feels like you swapped your bike for a bowl of Jell-O.
