I would check the carb holders. My KZ650 had a similar problem years ago. It turned out to be very fine cracks on the surface of the carb holders where they mate with the head. There were no visible cracks anyplace else. If you can get the bike to idle low, try spraying carb cleaner where the carb holders mate with the head to see if it affects the idle. Ed
I agree with Ed, but to answer your question.... yes, the pumper carbs are a direct bolt on. They added the accelerator pump in I believe '79 to make up for leaner EPA jetting. The "standard" jetting for a 650 was 102.5's but with the pump jetting was dropped down anywhere from low to high 90's.

On another note, Trying to bench synch, I can't get the slides open to the .032 spec, #1 will, but the other 3, even if I back out the adjuster all the way, won't come open. The book says to back the Idle adjust all the way out, am I missing something?

I used the main Idle adjust in the center to give me enough play to adjust the slides. They are all spec'd to the .032 in initial setting. Happened to be one of the carb cleaning tools that had a smooth part. Anyway, so after that I checked the floats to make sure they were where they needed to be. All good. Installed, tightened everything up, double check, triple check. Kick her over a couple times, she fires right up. Little rough, but figure the carbs need to get fuel moving, since she died a few times. Then she died, wouldn't start back. It didn't run for more than probly 30 seconds at most. Anyway, so I put the choke on, and she kicks back, even gunshots out the back. Take the choke off, feels like she wants to go, but doesn't turn over. Any ideas??

New spark plugs NGK B7ES would also be a good idea. Cheap piece of mind.
Have you looked at and checked the timing?
Good luck ... you will get there.
