thanks guys. One more question though.. if this engine has the chain oil pump.. I was told that's for 74 or older bikes. This is supposed to be a '76 KZ900A4 to the best of my knowledge. Is there something i'm missing?

What's the engine i.d. number?
Thinking a 1974 Z1 engine (complete with its 1974 28mm Mikuni carbs) has been installed in the 1976 bike. For whatever reason.
Maybe its a hopped-up 1974 engine.
Likely not a 1973, because oem 1973 engine was painted black.
Likely not a 1975, because oem 1975 engine didn't have chain-oiler.
1974 Z1 had unpainted engine and chain-oiler.
Engine i.d. number should be helpful. The number is located on a flat surface near the oil filler cap.
If the engine i.d. number has been obliterated, well . . . [you know].
Good Fortune!

And yes it is a hopped up engine.. not sure what the bore is... i'm hoping to talk to the builder when I get a chance.

My KZ900 never had the oiler. They'd been eliminated in 74 or 75.

where did you find these vin details? So you're saying this is actually a '73.. why does the vin have six digits on the bike instead of the 5 shown.

My supposition would be a 1973 Z1 engine including carbs (with black paint removed) in a 1976 KZ900 frame.

interesting.. I guess i'm just going to forget about the details for now a do what has to be done to get it running. i'm sure the guy who was doing the work 27 years ago will be able to answer my questions.. I hope
May ignore year of engine as far as doing what has to be done to get it running.
Z1 and KZ900 engines were basically the same.
Ramifications of hop-up would be same regardless of whether 73, 74, 75 or 76 900 engine.
What are questions regarding the hop-up?
My swag would be 4>1 plus overbore and perhaps a cam, which were common popular hop-ups at time. Guessing not much more, in view of the 28mm Mikunis being retained. As typically the next step would have been addition of 29mm smoothbores.
