Kawasaki kz1000 valve Kit standard

Hello everyone, do these valves part number 12005-005 and 12004-012 work for me on a 1977 kawasaki kz1000?

Thank you

Thanks for responding, could it be that from z1 to kz1000 the valves are the same and only the name changes in the manual?
thanks

Keeper grooves are different from Z1 to Kz1000 valves. Dimensions of both valves are the same, just the keeper grooves are different.

You have to use Z1 valves with Z1 valve keepers and Kz1000 valves with Kz1000 valve keepers.  THE KEEPERS ARE NOT INTERCHANGEABLE!!!!

I’m assuming it in the spring keepers. AFAIK the valve sizes are the same. I don’t find your valve numbers on any 900/1000

Z1-Kz900 =12004-012 INT 12005-005 EX
77-78 Kz1000 = 12004-1010 INT 12005-1009 EX

Well I'll see what I buy, thanks

Apart from the injection models all kickstart equipped Z1 through to MK2 use the same size valves.
However the early stock valves had square valve keeper (collet) grooves and ran in bronze guides and the later had round grooves and cast iron guides.
Due to the different materials used you cannot run an early stock square grooved valve in a cast iron guide so make sure the valves you buy have a rounded groove as these are compatible with the cast iron guides of your 1977 engine.
 

Thank you very much for the information, I also plan to replace the guides.
