I just pulled these Carbs off of my 72 and I'm guessing that they are not the originals. Can anyone tell me if they will work or where I can get a rebuild kit for them? they are keihim carbs and stamped saying PD with 42BAPKY engraved into them. All help would be appreciated.

Nope not originals. They are off of later year 750. Go to http://www.cb750supply.com/products/6/fuel-system. The biggest pain will be making sure the accel pump passages and check valves are free and working correct. Check to make sure the accel diaphram is in good shape if not replace it as well.
 
replace the diaphragm and gaskets for accelerator pump. they are cheap. better yet have someone professional and familiar with these old carbs rebuild them for you. I spent 100$ on parts and cleaned and scrubbed for weeks at a time and got no where. had them professionally done and poof all problems solved.
