1980 KZ1000 Classic with Fuel Injection that Stalls

It seems to me that I am getting way too much fuel causing the engine to flood. I have heard that I may need a new computer, airflow meter, or cold start sensor. I tried to disconnect (also ground it) the cold start sensor and had the same result. If I shut off the fuel supply it seems the bike runs great until the fuel runs out. Could it be that my fuel pump is pushing too much fuel?
Does anyone live in Metro Atlanta that might be able to help me solve this problem? Perhaps you have the same bike.
Thanks,
David

We're glad you're here.
Have always admired the beautiful
1980 KZ1000 Classic. :woohoo:
Will defer the specifics of fuel
injection to better informed
members. But do know that owners
often elect to replace the injection
system with carbs.
Good luck!

Update: Today I replaced the battery and noticed hours later that the injectors are still hot (with ignition off) and the computer was hot as well. Obviously, the injectors are wide open and the only way I can cool them off is to disconnect the battery. Any thoughts on what is causing this problem?
Thanks,

It would kill me to replace the
fuel injection with carbs. This bike
is original with only 11k miles.
What does it cost to convert the bike to carbs?

Just guessing, but it seems the wiring
diagram could help identify the electrical
component (such as the ignition switch
or related wiring) allowing continued
voltage to injectors and computer with
ignition turned off. If don't already
have, would obtain FSM.
Meanwhile, there's a small "Search Forum"
box toward top of the page. Typing in
"KZ1000 Classic" will return many
informative earlier threads. Typing
in "KZ1000 Classic fuel injection" will
return fewer earlier threads.
Concur with desire to keep
original, if feasible.
Good Luck!

A link to the wiring diagram appears -- I couldn't get it to download , but maybe it will download for you.
Good Luck!

I've bored out the injector port to accept the ubiquitous Ford 19#er, then made fuel blocks for the top of the injector:
Then converting FI control to MegaSquirt.
If you want to check it out, remove everything from the throttle plates on upstream, then hotwire your fuel pump to 12 volts and see if you have dribble/spray in your intake runners. If you have a leaker, you'll find it this way.
