Need help identifing which carbs my 79 kz650 has.

 My throttle releases very slow. It's not the cable bcuz u can hear the slides sticking and hanging it up from operating smooth and keeping my throttle from snapping back. Also it's like their sticking and choppy when giving throttle. Here's a few pics of my carbs..
One flange says 106 9A
Flange under choke says N7 Y 2     

That is a set of 1069 carbs that to the best of my knowledge were stock on some 78,and 79 650 models. In the past I created some tables of the carb info I could find about the stock carbs on the 650s You can find it in this thread   kzrider.com/forum/3-carburetor/617948-ar...-for-a-d1-650#871540

I see you are running pods, you may want to check out the air corrector jets from zed1015 

simple answer is vm24 carburetors. found on most kz650s thru 1981. there were multiple iterations of them. some from 1977 were actually vm22s. in the u.s. many had an accelerator pump. from 1978 or 79 thru 1981. 

Post a picture of the full rack from the airbox side and another from either end and lastly from underneath. 
If the bodies don't have ribs they are Vm26 or bigger. If the bodies have ribs they are vm24's or smaller. 
Only vm 22's have a port at the 10 o'clock position on the inlet mouth. 
Both vm22's and 24's had either fuel screw, airscrews or both depending on the market they were originally sold in.

As others said they are a set of Mikuni VM24ss carbs and were stock on several different models. 

The pic shows they are off the bike and I would suggest they could use a through cleaning since the slides appear to be sticking.

Ribbed for HER pleasure. It had to be said.

Yes, someone had to do it.
