Agree! Even if the petcock fails and lets fuel flow with the engine off the floats should stop the flow when the fuel reaches the prescribed level inside the carb bowls. Ed

Yah now that is all good and taken care of and figured out. She runs great and everything seems like it was before I cleaned the carbs. Where are the screws for which I plug my carb synching tool too?

Rubber plugs not screws



First set carb ( #1 and #2 to equal value ), then ( #3 and #4 to equal value )
Then adjust the both pair ( #1/#2 ) and ( #3/ #4 ) to the same value.
Replay this procedure till all carbs are on the same value.

Just a note about non - vacuum KZ petcocks - I have a customer's KZ that had the internal valve parts installed backwards or 180 deg. out when he brought the bike to me. It has been such a long time now that I forget exactly what was wrong with that (operationally) that made me take it apart, but I seem to recall that the petcock shut off flow completely on RES, and ON allowed the tank to run dry...something like that...

Yes, and sometimes folks will modify a problematic vacuum petcock to make it function manually rather than rebuild it as stock. If yours has been modified intentionally or accidentally, it may not act as it should. In any case, the carbs should not overflow no matter what the petcock is doing.
