  2. Hard to diagnose but get your mechanic to look for....

    1. old fork oil
    2. sacked-out front springs
    3. worn steering-head bearings

    Oh, and check for loose dentures :LOL:

  3. Does the bike wander at low speeds and follow grooves in teh road?

  5. If bumps, it could be your shaft absorber.

  7. Can also trying checking with emergency stops as this will load the headstem in the opposite direction and only gradualy load the forks. If clunk is still there I would say head stem bearings loose/flogged out. If not then look at suspension, but more likely is loose body part, or something knocking like brake line bracket etc.

    Cheers

  8. Stick the bike on it's centre stand, get some one to help hold the bike and keep front wheel of the ground.

    Now start pulling/pushing and kicking everything in all different directions looking for any movement/play what so ever.

    Spin that wheel and move handle bars slowly from side to side (left lock, right lock) and movement should be smooth through entire movement. ie, no sticky/tight spots through movement, especialy when centred.

    Failing that, start yelling and screaming at the bike. A neighbour may hear you and come and assist in finding the problem.

    Good luck.
