I had a kz440 for my first bike. I traded it in, and wish I had kept it.
I currently have a kz750b (big brother of the 400/440) in my garage waiting as a project.
I also have a cb750, but that is more of a resto project.
Here is the only kawasaki twin forum I have found. There are some nice builds posted. http://www.armbell.com/kz400/index.php?sid=d9b8f7cf456af3f4dbed2137fdab4cb1&mforum=kz400
