Welcome from central Massachusetts. With those two bikes they'll definitely let you in! I've owned my Z1A since the late 70's, rode it for 18 years then life happened and it got put away until last year. (Some of that time was in a friend's leaky garage, so it has some issues from the storage) I retired last summer and I'm reviving (not restoring) The plan is to make a safe good running older motorcycle to ride. It's almost ready to go, so I'll be following your project with interest. Sounds like you've got a decent amount of Kaw experience, the members here can help you solve any issues you run into. And by the way, we really like pictures!
