Help! I was having problems with the CDCV carbs from my 2000 1100 zxi. So, I bought a set of used CDCV carbs on Ebay from a 1999 Kawasaki 900 stx. As far as I could tell from the Kawasaki parts diagrams, the only difference was the jet needle. Here's where I screwed up big time. I started changing parts from one set of carbs to another without keeping track of which were the original 1100 carb bodies. Not too bright, huh? Anyway to make a long story short, is there any way to tell the carb bodies apart? Each set of bodies has identifying numbers stamped into each carb. One set of three carbs is B731A NK3 and the other set of three is B735A PF8. Can anyone tell from this which is from the 900 and which is from the 1100? Jetting is the same on the carbs, but my concern is that the idle air pilot screw is adjusted differently. Help!
