That's my understanding.

Yes yr right.  I guess if all the floats were of the correct (22mm).  Then the fuel height would all be correct.....

Or stick a bit of clear tubing on the bottom of the carb and see what the fuel level actually is without having to take the carbs off (yet again).  And take apart.  I will try this to see if all 4 carbs are the same.  Which is a start.

So... it's about the float height in other bikes than the K3?
This method - given that it is a good idea to drain the floatbowls once a year - is still the simplest.

So I tried the method given above and found all 4 carbs seem to hold 27 to 27.5 ml.  Just one carb was more than the others by .4 ml.

Then I tried putting a clear plastic tubing on each of the carbs.  3 were almost the same with one nearly 4.5 mm less than the others.
Is this an issue??..  Dont know, but I will try to adjust it so it's the same as the other carbs. 

The Kawasaki is very sensitive to fuel level heights which is why I wonder if the honda is also
