the only pict I have, this pict is for the 85, when i installed the central washer nozzle because the OEM tubes were broken, and hard to adjust the spray.
remove screws on the cowl, and slide forward, on the earlier years you need to remove the washer nozzle nut that is a bit hard to access because it is recessed on the under side of the cowl -removing the air filter will help a lot.
