Front end knocking sound on bumps

[exzachtly1]

And as always thank you for the other suggestions. I don't think it's the gas tank, I just had it off and all the parts are there and secure. Steering bearings and wheel bearings are on my list next if this current fork rebuild doesn't do the trick. I'm just a bit hesitant to spend 50 bucks on the bushings if I don't have to, so curious what you all think about how they look... and is there a way I should be checking for play in those?

Good thing to keep in mind, but GSes don't have floating disks.

1150's have floating discs.
Mine has a clunk that under braking that is related to the pads / calipers.
