I have been attributing my vibration due to poor tires.. now I am sort of wondering.
Driving normally @ speed in a straight line I get a slight "wobble" if I let go of my handlebars. The wobble can be seen visibly while looking at the bars. Movement is oscillating about 1/2" travel at the end of the handlbars.
Is that the headshake that seems to be prone in 929's? Or am I imagining problems?
