A test for front end "clunk"
All you folks who have a front end clunk, it isn't necessarily the front shock, although it could be. Try this:
While riding over a road surface that causes the clunk, feather your front brake. Don't brake hard enough to significantly slow the bike, just enough so the brake pads are pressed up against the rotors by the caliper pucks. Make a few runs over the same surface, comparing noise when feathering the front brake and when not, make the runs at the same speed irrespective of whether you are feathering the brake or not.
If the clunk goes away, the clunk is being caused the 4 brake pads all banging in unison inside the brake calipers when you hit a bump.
