I am sorry i don't know the correct terminology but i am not a native English speaker. (and i don't know the correct terms.).

Well I have a small "problem", just bought a new bike an noticed when i pull the steer it clicks a bit up (and down when leaning on it). http://cl.ly/1X0j0P0A1e3o1E2J3R1M

I pull the screw a bit harder to stiffen it put but doesn't help.
Any thoughts? I could go back to the shop but I currently have no time.

Thx
