When is the headshake occuring? During accelleration or when you chop the throttle?

headshake on a roadracer would be a sign of something not quite right. now there's loose and there's worn out.
headraces. check for play, check for the rumble, re-grease.
swingarm bearings. check for play, check for grease.
wheel bearings. check for rumble, check for grease.
then you can look at alignment. tracking of the rear wheel ( a real favourite). twisted forks, worn fork bushes.
listen, these bikes don't weave or headshake as a rule. i had it last year and it was cured when i had the forks re-valved. the 98/99's are well known for a poor mid stroke damping.
i also found the SA bearings went AWOL. now i ride with the forks through 13mm and no problems.
a stering damper disguises weaknesses in a bike's set up.
i'm not poo-pooing a steering damper, i've got one as well now!

Did you put "Austrailian for big tyre" on the rear?
I had a friend that put huge meat on the back of an XR 350, it gave new meaning to "weasel in a drainpipe" which is how one of the magazines described the "stock" steering caracteristicks.
Anyhow the wrong size tire could induce it.PT

wifes ttr 230 used to shake at about 80 ks but with a little less front tyre pressure it has reduced.
just a thought, hope it helps.
