wobbly frame?

I've got Murph's fork brace on mine and it seems to have helped stabilize
the front end under heavy braking noticeably. To the earlier question about
wandering while street dragracing, the brace won't help, you're light on the
front end under serious full on throttle.  I have other bikes for that kind
of activity but my GPZ will wobble the front end if I let go of the bars
while slowing into a light.  If I were going to really thrash this beast I'd
agree that a steering damper is what you need.  I probably have a couple in
my garage but you would have to fabricate your own mounts, which wouldn't be
for the faint of heart.

I used to have this issue with some weekend racing at the track.  A steering
damper solved it.  Minor oscillations and vibrations at lower speed are
really magnified at high speed.  The damper took care of it, at the expense
of relatively heavy steering at low speed.

If anyone has experience with the fork brace, I'd love to hear about it.  Is
it really helpful?
