Get the bike in to the dealer. Mine doesn't have this problem, but I have heard of a few that HAVE had problems with the valves. Get it checked out if it is loud and persistent. If it's just the quiet ticking that's present when the bike is warming up, that's normal, but not if it continues when the bike is hot and if the ticking is loud. Besides, can't hurt to have it checked out and documented.
Keep us posted.
