So i have two fzr's. One, my dailey driver, is a 93 non-exu op and i just picked up a 91 ex-up (judging by the vacuum tubes connecting carb three and four). I was cleaning both sets of carbs and look at what i found. The four on the left come from the ex-up while the four on the right come out of my 93. Much different shape and size. So, here is my question: did the 91 ex-up and 93 nonex-up get different sized needles or has my 93 been jetted? If it has been jetted, can i assume that the emo tubes would have also been switched to allow the thicker needles to sit correctly?

There is something in the wiki that will explain tbe different carb needles.

This is it. Stock needles have no clip positions.
