GP, I asked this previously, but haven't seen anyone reply.
Is a valve guide available from Kawasaki to replace yours?
As your valve guide is toast, I suspect the valve seat is also damaged.
I think the parts (valve, seal, guide, seat, spring, keepers) and machining costs will be more than buying a used head.

YES
I noted above it was, and he did find and post that p/n, but he wants to take on the replacement.
that being said, the steps are not cheap, or really simple...
any new guide must be reamed, using Kaw reamer 57001-1079.. especially a new guide as the action of pressing it in, reduces the internal diameter, and once in place must be reamed (even tho the slip fit of the valve stem and guide seems fine when you are holding both loose parts...) (but they also specify even reaming the original guides before installing valves, to remove any knicks or burrs..), also, to remove and install the guide, you will need Kaw valve gude arbor 57001-1021, to correctly and safely remove and reinstall the new guide to preclude damage... those 2 tools alone break the bank..
$140+

then, you have to heat the head, in a localized manner around the guide, to about 300*F, to remove the guide' and again to install the new one..
The seat however, is not really user serviceable, and without critical measurement, to see if it
could be slightly re-cut (again, some expensive Kaw specific tools...), and the new valve re-lapped in, without exceeding the nominal service limits of diameter and depth, its a gamble.. even then, it becomes necessary to remove some stock from the end of the stem then, to bring the new valve to an overall length, to function with the keepers and spring retainer combo, and prevent another failure.
I've done guides, but only for reasons of internal wear to reduce oil consumption, and install new seals.., not a catastrophic valve failure, replace,
even with my skills, and accumulated tools, I would have simply bought the head when it was $75,(which WAS totally complete, top to bottom, and even had a nice looking cam cover, with the reeds and covers in place..) removed the cams, rockers, and loose parts, from the bad head he had, boxed them up for sale or future use and taken the head into the scrap yard for beer money. People here, and on the COG forum are always willing to buy cams, rockers and such...an actual profit could have been seen, selling off the used parts.
I suppose I understand somewhat why he wants to take on the challenge, but I've seen this soo many times I always wonder why, it's not my bike, so I can't say much.
I wouldn't want to be a person that purchased it tho, sometime downstream...
I would by a bike that had a fully assembled, from a running bike, head swap, if I was told it was done.
