there are two "clips" on the top of the airbox, the righthand one, which runs over the center of the airbox carries the vent tube from the carbs. The lefthand one carries the wiring harness. The B4 manual can be found in the "members only" section of this forum. There is a sticky thread that tells you how to get them. Beware, if you have a '93, some things have changed --- the '93 changes are in the last chapter of the lo-res version but are not (to my knowledge) in the hi-res version.
