How fast exactly are you going over said bump? do the shocks compress a lot when you ride over it? enough to hit the bottom of the stanchion? if so, its prob that...

Is it only speed bump's this happens with or does the noise happen when you ride over pot holes and the like too?

could it be the steering head bearings?

It very well could be the steering head bearings, but it also could be the forks need rebuilt. There's bushings on the fork tubes and when they wear it it allows it to slop around a little bit, and will also make clicking/clunking noises, especially when you hit the front brakes pretty good

First thing I would do is check the torque on your triple tree nut (the funny shaped one), make sure it's good and tight (to spec). Sometimes that's all it is

Hold the front brake and jump up and down on the bike, see if you can replicate the clunking. Might help you further locate the origin of the sound.

I second the steering head bearing theory.
Your triple tree crown nut may just be loose. I would check it first to make sure it's torqued to spec. I believe it's supposed to be 72, or 74 ft/lbs.
Verify before tightening.
Sometimes when it's loose it's difficult to tell unles you are rolling and grab a handful of front brake.

Ya i believe it is the steering head bearing I have done everything else. the tripe crown nut it tight when I hit the breaks and move up and down it dose not make any noise its only when I go over bumps

Are you talking about the nut on the very top of the triple tree?? If so, all that does is hold the upper triple tree in place to the stem. The nut below that is what puts the preload on the bearings, which is the one you need to check. It looks like this...

ya I was doing the one up above where is that one I didnt see that one ?
It's right underneath the upper triple clamp.... gotta take that top nut off, then take the upper triple clamp off, and then you'll see the goofy looking nut. If you have a spanner wrench you can use that to check it (I forget what the torque spec is though), just gotta drill a square hole in it for the torque wrench and adjust torque spec accordingly for how far away from the nuts center you put the hole. Otherwise a 4x4 hub socket works too, just gotta find the right size

Sorry to bump this old thread, but did you ever solve this issue? My 2003 600RR started doing something that sounds like this today but only when I'm going up steep driveways and over speed bumps.
