Cam chain rattles when cold

[treytexag_imp]

I have a rattle when my CB1100 idle's. I don't remember it being there until recently. Bike has about 800 miles on it, changed the oil when I brought it home, and changed it again with Honda Full Synthetic 10W-30 at ~625 miles. Used Honda oil filter both times.

See if you can hear this rattle. When I speed up the engine slightly, the "rattle" goes away, then upon idling again, rattle returns.

Is this my CAM chain rattling or is it something else? Any reason for concern? My warranty period has expired.
