I'm out if idea's.....
I just let rebuild the rear shocks in the factory (new inner valves, oil, refilled with gas, other shims and so on..) I bought new top mounts and still there is a clonking noise when I hit a bump, not all the time but sometimes.....

Really p!ssed now...

Look at your antiroll bar mountings, particularly the anti roll bar drop link bushes. Change 'em to polyurethane or better still uprated drop links. That may cure the problem. Use a crow bar at the bush end of the drop link and see how much movement you get.

 

Defenitely NOT the roll bars, as I had a test ride without the rear one !!!! (funny to drive tough...)
