Can anyone say if '96 ZX11d carbs could work on a '92 c model? I actually have d model exhaust. I know the twin air induction system is different, but what about where the air box mounts to the carbs? Any ideas?

Thanks, John, for that tip. So does that mean the D carbs wouldn't work on my C? (Testing for understanding... ...) Ed

Yes they will work..but won't fit because the intakes on the c are shorter..therefore the air box and tank etc won't fit on properly. I've never tried putting on d's but I did put on kein 41 smooth bores and the intake manifolds are different in size for c and d. They sent me d's for my c and I didn't know..so end result was to modify everything to make it fit..it works..but it was a lot of work in doing so.

Are you sure? From all the reading I made over the years, you can interchange carburators from D to C and vice-versa with no problem at all. The only difference being larger main jets (D have 162-158-158-162 while 1990~1991½ C have 4 x 155 and 1991½~1993 C have 4 x 140).

Like I said Claude..I've never tried it but with the 41 smooth bores the d models have a one inch longer intakes then the c models...as for the stockers..they should be the same except for jetting..but ..are the intakes longer or the same?

By "intake", do you mean the rubber adaptor bolted on the head or the section of the carb's body that enter through the rubber adaptors?

I am 100% sure both carbs (between C and D) interchange (same casted bodies) and that only jetting is different.

Thanks to both of you for the info... not trying to get anyone into a snit... I wish I could just make my carbs work. The bike only has 8k on it and is in near showroom condition. I know all the sitting around its done hasnt helped the carbs. I've been thru them a few times, and found some clogging in certain air passages, and havent actually vatted them, but cleaned them well w/spray carb cleaner. (Im not new to m/c carbs). I know the jets are stock according to the fiche. They look like new inside and out. This last overhaul I 'gently' used tiny torch tip cleaners to clean, and now it runs worse than ever. I can get it to run too rich, or too lean, but never just right. (It was fowling plugs after about 50 miles, or less during its worst case scenerio). So I guess I've screwed them up or something... and I saw these D carbs for sale on this board so thought I'd ask... Thanks, guys... Ed

Not the rubber manifolds but the intakes on the carb body's. Are they the same (c&d) not sure? Maybe the 41 smooth bores have the longer intakes because of the double snorke and larger airbox?

I never had smoothbores available to look at them but OEM carb bodies are the same for C and D models; only jetting is different. I suppose smoothbores differs to OEM then.

Had a quick look at the Kawasaki parts lists & the part numbers are different but the carbs look the same.

If there is nothing amiss with the carbs it may be a blockage that you cannot get to. Modern fuel tends to gum everything up if it is allowed to evaporate off over a long period or in an older bike that has not covered much mileage. Have you used an airline to blow fuelways out?

It might pay to get the carb bodies & jets cleaned ultrasonically if you can find someone local to you that can do it.

Thanks to all for your help. Yes, I ultimately think that I have blockage from evaporated fuel that wont wash loose. GOOD NEWS, however, the ZX 11D carbs that I bought from Mike B. from this board ( recent post selling parts from his blown motor) absolutely worked out fine and absolutely fixed my bike up! So I gambled $100 and won, and answered my own question!! They are completely interchangeable. Thanks to everyone! Ed
