It is the catch can for the airbox. If oil gets into the airbox from the crankcase vent it will collect in the bottle. The plug is there so you do not lose ram air pressure and so that oil doesn't get on the rear tire or track.
Hey guys, This may sound like a dumb question but I gotta ask, I was looking around my bike yesterday (96'ZX6R) and I noticed a little plastic bottle behind my shifter with a tube going up into the bike. What the heck is this bottle?? and what is it for??
