Bike on center stand, get the front wheel off the ground. Slowly move the bars right and left; if there is a "detent" (or flat spot, as
says) anywhere, this *will* cause a wobble, and you need new steering bearings.
If there isn't a detent anywhere, then use your manual and adjust the steering head nut / lock nut accordingly, just to eliminate that as a possibility.
(BTW, if you have a dented front rim, then you almost certainly have a detent in your steering head bearings.)
