I just got my2004 f4iback from the dealer a few days ago. I notice that when i push my bike back and forth I hear a slight hiss from the front, also when I am using the front brakes at above 30mph I hear like a buzzy sound..The new brakes work real well. I was wondering is this cause they are new or are they in need of adjustment? My bike has 10k

The sound you hear from the front when you push it is brake drag and is considered normal.

The buzz could be from the pads seating with the rotors, check to make sure there's no scoring on the rotors from debris.
