I had the high speed curve wobble when I first got my 97 WG. After rebuilding my front forks and new springs and new rear shocks the problem went away. Now it rides perfect. I would have to deduct my problem was soft or bad shocks.

 

Contrary to what HD will admit to, that has been a problem for some time with some models. That is one of the reasons that a lot of police departments have stopped getting HD bikes for their bikes.

This place has what they claim will fix the "wobble of death" problem.

Here's an Update. We went on vacation to Italy for better than 2 week s and before we left I changed the handle bar air valve and filled it with 15 lbs and when we got home still had 15 lbs. I took some air out for a better less solid ride to about 9 lbs and went for a ride and air held. I went out for another ride and again got the wobble ( not in a curve wobble). Guy in town here does flh front fork oil changes for 70 buxs so I thought worth a shot. He showed me the oil, it was ugly black and short .He refilled with 10 oz in each fork of 20 wt and I just came back from a 2000 mile ride and had no issues at all, go figure.
I will be doing the swing arm rebuild next just because.
