Will do. I'll make a swing by the LBS and pick one up.

Nothing is making contact with the headtube and the fork steers/ turns without resistance. The only time I feel or hear a rattle is when riding over a significant bump, or by holding the bike by the handle bars and standing it on its back wheel, if I pick it up and let it bounce I can hear the rattle in the headset.
