Re: CBR 954 RR
its a cable guide from the htev servo located down under the gas tank next to the frame. the servo has one cable to the exhaust valve and one that goes up to the flapper found inside the air box.
the cable can be unhooked from the flapper inside the airbox, then unscrewed at the angled piece you spoke of and threaded out of the airbox in order to remove it.
dean, the best advice i can give you is get online and download a copy of the service manual. a quick google search should turn up a few sources. or buy a hard copy for future use.
the service manual will greatly help you as it has step by step instructions on how to do just about everything you can do to the bike. along with assembly instructions, torque specs, maintenance intervals etc.
