you need to take all the gubbings off first, this includes vacuum hoses, PAIR hoses, electrical connectors.
if you look between the frame spars at the bottom of the airbox you will see a band (jubilee clip) on each of the throttle body mouths, you need to loosen these (dont completely undo these or your in for some fun) to lift the airbox off.
there are shed loads of connectors and hoses going to the airbox. if your bike is K7 or above you need to make sure that you have connected everything up again of or your bike will throw FI faults.
have fun
