"If you get a shimmy and more tightening does nothing to help, then suspect that the steering head bearings have shifted and the races are no longer parallel to the axis of the steering head. This is not unusual in HD bikes as they are relatively heavy. Modern bike head bearings tend to shift back and forth in the frame, especially on the heavier bikes, and this causes the bearings to become non-parallel. Any free play in the head bearings will compound this situation. This sets up torque forces that constantly try to correct themselves resulting in a shimmy, or head shake. The cause is not looseness; the bearings have shifted, and things ain't parallel. Pull the front end off and try to reseat the races in the frame neck."

This is a fairy tail. The steering head bearings have NEVER shifted or the races become non-parallel in my 26 years of turning wrenches on bikes both professionally and freelance.......its just bunk.
