I paid for and received from PitStop performance a cylinder head (kz1000). It is ported.
The valve guides fell out and bent several valves plus breaking one.
I put a set of Mikuni RS34 on my 1000 and they fit.
Ordered keihin cr carburetors for 2 years and could not get them.
I order Murray Carbs out of North Carolina (kz650) and that end up being a disaster. Everything hit something.
Finally got the CR carbs after 3 years off Amazon of all places. Guess what. I have to modify the fuel petcock.
i now have:
the last kz650 nos cylinder head.
the last black kz1000 head from the historical parts department of Kawasaki .
4 complete sets of new carbs.
8 cams sets
3 sets of wheels
I had a fire on the 650 from the wiring harness, so i got what was advertised as "nos". It caught fire.
I just went ahead and get a complete system from z1 parts for a 1977 1000 for my 77 650.
Now I can not find even the parts for the rear brake master cylinder for my kz650.
