I installed the smart nozzles on my 88 Westy and they are a very nice
improvement....can't remember what they cost. I purchased them from one of
the guys on that nozzle thread that Alistair sent you. Some aspects of the
installation can be a little dicey. Losing the tubing into the cavern is a
huge possibility. I used forceps to hold them in place and this worked very
well. Proceed with caution. Based on my results, I recommend this
upgrade....
