I have being trying to get a KZ1000 ST to run correctly, I've changed to Dyna S ignition. Carbs cleaned and look like they are in good condition. Bike has done approx. 15000 miles. The accelerator pump has parts missing so I replaced all the float bowls with standard ones.
Bike starts and runs on 1,3 and 4 very well. Will not run at all on no 2 where the pump was.
I have set float height as per the other three and the plug was wet. Lowered the level slightly and no petrol getting to cylinder.
Question is... is no 2 float height set differently because of the pump as standard and where should I set it now that the pump is removed?

Yellow, have a look at the small orifice in the lower centre of the throat nearest the engine. I'll bet it's blocked, unfortunately you will have to remove carbs and clear it with something like a "primis pricker" (a fine needle at rt angles to a long-4" handle). Compare that orifice with 1,3 &4.
Note all float levels are set the same. I expect the carbs are 26 or 28mm Mikuni high tops.
Also check you have blocked off the breathers, I seem to recall people often, mistakenly, run there fuel line into the breathers on those carbs.

I'll be interested to see how it goes on the Z1000-A2 carbs.
If it is still not running on #2, swap leads from #3 and check!
If that don't work, you will have to check that #2 carb for blockage or air leaks.
Also, have a look at your advance retard mechanism for lack of movement of plate, at the back of your DynaS. (Unlikely to be this!).

Assuming you have a spark at the correct time & fresh fuel on call ........then stick your thumb over plug #2 & spin the starter motor........did your thumb stay there ? = rule out or in a compression issue .
