Kawasaki 1979 KZ400 H-1 valve lash

I've a library of manuals but nothing that pertains to this bird. Does anyone know the recommended valve clearance? She's a pile ha.      

Clay, I found a couple of pdf manuals that may offer some help.

Awesome fellas, THANKs for the info!! I wasn't even thinking about the camchain tensioner checking but will do that too. Your info is tremendously helpful! I've just never worked on these little tiny machine offerings, thus the lack of info i have. KUDOS!  

I had to bend my feeler gauge to make it go in smoothly if you dont have pre-bent feeler gauges.
