Mine is similar: it clunks on bumbs and front feels unprecize sometimes wobbles when hands off. Also it wobbles when I drive on paint like the centerline of the road.

Krisztian... I'd say headrace. If you can feel paint, headrace. Support the front of the bike so the wheel is off the ground, grab each fork leg and lift it straight up as it you were picking it up - there should be no movement. You can also move the bars very slowly from full lock to full lock with the wheel off the ground and the action should be smooth. As it wobbles it could also be your front wheel bearings but in my experience if you are getting clunks and can feel white lines then I'd say it was ya headraces mate. However, check both. Either pop the front wheel out and physically turn the bearings with your finger in the wheel. They should be nice and smooth all the way round. Any grittiness, seizing or unsmooth action means they're worn. I'd check both ya wheel and headraces.

Check out the floating buttons on your disc also, mine are slightly worn and sometimes make a clunk if you brake, can feel it when you're pushing the bike around

ive got this problem at the min, with a duc front end im putting on my 30, there is no movement and its all smoth from lock to lock when the bike is off the ground, could it just not be tight enuff? it sounds and feels very much like the headrace gubbins and the sound is still there when moved with or without the brakes pressed, ther is no mudgaurd or fairings fitted to the bike just to make sure it wasnt them causing the problem,
most grateful for any ideas cheers,
Bill

Yes, it was the headrace bearings...
