Try riding the same road that caused the clunk, but with slight front brakes applied.......if the clunk doesnt happen its just the floating brake pads and floating caliper.  You can minimize this by making sure the calipers are clean and the springs that hold the pads in place are not mashed down too much

Had the calipers off not long ago checking the pads (but after I had been hearing the clunk)and they look normal....almost sound plastic....could the headlight be loose?  I have a week of Vaca next week, if I get the chimney work done early...should have time to look into it...also got new shock bushings on the way.
Thanks Chris

My chrome front fender extension had a broken mount and would bounce when I hit a bump.

My VTX had a electrical connector that would bounce in the headlight bucket.

Check the torque on the head bearings.

I'm betting one of your fork leg dampers came loose from the fork cap. If you remove the fork cap, the damping rod should be screwed into that cap and locked with a lock nut. If not tightened properly, these have been known to work loose.
Don't ask how I know and who tightened them wrong... uglystupid2

I have the same thing happening on my CSC Trike.
I had a new rear tire installed as a front tire. Went back the Dealer, he coundn't find anything wrong. Thay was a waste of time and money.
I sure sounds like the headlight is loose, however it is not

You can always put it on a lift and try to replicate the sound... rubber mallet to the front tire.

Valker is on the correct path regarding the clunk coming from the front shocks.

I, however, feel it is the tubes themselves (or one of them) it is worn and that clunk is the slop between the slider and the shock tube.

New bushings, guides and related parts will fix that for you.

With some help from someone who knows, they can help you identify the looseness. it's the same kind of testing you would do for finding looseness in the neck bearings and also similar to testing for indexed steering stem bearings.  A little tricky but easy if you know how!

For what its worth, mine has done that from day one, when it was new.  It had 2 miles on it when I drove it home from the dealer.

Check the chrome side covers on your radiator.
I can't believe I missed this.
Pulled the reflector, tightened the button head screw and 90% of the noise disappeared.

Had this problem a couple weeks ago. Actually had the problem for a couple of months and finally figured it out a couple weeks ago.

 It was a loose brake pad in the right caliper, inside pad.

The thing about this is that when I hit a bump the pad would make a loud 'CLUNK" which sounded like it was coming from the front fender. It sounded like the brake hose was slapping the fender and hitting it really hard.

Took me weeks to figure this out as the sound never seemed to come from the brake area but much higher up. I knew it was brake related though because the sound would not happen when the brakes were applied. One day I took my finger and pushed up on the guilty pad and "CLUNK" goes the fender.

Apparently the fender acted as some kind of amplifier/speaker.

Had the guy who previously worked on the brakes readjust the pad spring and problem solved.
