Motorcycle Repair: noise when hit bumps, lehman trike, trike kit

Question
I recently started hearing a 'chirping' noise when I hit bumps on my 2005 1200C HD that has a Lehman trike kit installed.
As I hit the bump, I hear a 'chirp' that seems to be coming from the front end. Suggestions?
It started after having an HD dealer so some work on the trike.

Answer
I would first check the front end to make sure everything is tight. Check your brake pads in the calibers to make sure they are not rubbing. Probably the only other thing it could be is a fork spring rubbing in the forks.
Good luck and happy riding
