The carbs were not properly adjusted before installation
-- bench synch the throttles and preliminary float adjustment.
The throttles are hanging open
-- twist grip is dirty or damaged
-- throttle cables are damaged, dirty or kinked
-- return spring is missing or broken
-- throttle shaft is damaged
There is a serious air leak
-- the carbs are not fully seated in the carb holders
-- the carb holders are old, cracked and leaking
The ignition advancer is stuck
-- rust and lack of lubrication

Do you have a factory service manual? If not, you really need to get one. Check under the Articles tab on this forum to see if the one you need is there.

By the way, KZ750ltd has Keihin CV34 carbs. The screw is a fuel screw, not air. it should 2.5 turns out as the service manual recalls.

Yes, my previous post was based on the completely unfounded assumption that the clean air system had been removed. If it is still in place, two of the vacuum ports will be connected to it, and only one will be capped. Be sure to use high quality caps as the cheap ones will dry out and begin to leak rather quickly. The factory ones are really good.
