Sorry no replacement!!!!!
The cam bearing holders are machined together (mounted ) with the cylinder head.

Take some pics for a better repair solution

I'm not super familiar with the big KZ engines but on many similar engines you can exchange caps without issue. The caps are line-bored with the head but the manufacturing was quite accurate such that interchanging caps rarely causes issues.

Regarding that crack, is it possible to simply align the crack and bolt the cap back on the engine? The bolts will hold the cap in place regardless of the crack.

Some of the advanced members here in the forum use screw clamps to tension the cam shafts down to prevent such a damage to the cam caps.
Sorry didn´t found the picture yet.

He broke it at the lateral guides of the cam shaft. I suspect that the Cam shaft was not lateral centered

The way I broke it, I was getting in a hurry and did not see the bearing had slipped to the side so when I started to tighten it snapped.

if the threats of the cam caps are in good condition your are on the safe site (do not over tighten them).
later ( i hope not so far ) if you must do a maintenance to your engine, you can welded the cap when the cylinder head is removed.
Good luck and enjoy your ride.
