I was bored at work at pulled up the parts fische for the Z and read the service bulletin at the bottom. Aparently Yamaha had some problems with the Z (85 only) running in cold weather. They had a list of things a tech should replace if anyone brought them in for the recall. They had an updated headlight housing with less air vents in it along with a front fender and they removed the little breather line to the air intake from the carb and lengthened it up towards the airbox. there was even somthing in there about drilling out the main jet with a #4 drill or somthin like that. those are some of the things that are different from the 85 to 86. They also had a part about the diaphrams in the fuel pump leaking and how to go about replaceing just the diaphrams cuz I guess before they made the dealers replace the whole fuel pump. They even had written in how many hours you could claim for each warranty repair. I wonder how one of those fische things would scan with a scanner? I just thought it was a little bit of good reading. Another thing is Yamaha is the only manufacture I have found to put all the jetting specs and optional equipment part #'s on their fische in the service data section. The fische have proved to be very helpful on a couple of machines I had to work on in the shop for customers.
