Z750 ignition barrel 1980

Hi everyone,
Im new to the group, just looking for some advice / help
I have a Z750 / 1980 the ignition barrel works fine but has lost its grip on the key, can you get a tumbler kit or is it a replacement barrel and key?
Thanks

A lock smith sould be able to re-new the wafers in the barrel by the key code

I'm a Locksmith.
I have never seen a Kawasaki tumbler kit available.
Have repaired many Chrysler, Ford, GM, Honda cars, and Toyota locks over the years, but never a motorcycle lock.

If the key is worn, having a new key cut to factory specs may keep it from pulling out of the ignition when on.
