KZ 400 clutch engine identification.

I have what I was told and believe to be a 1975 or 76 kz 400. I was wondering what exact model it was so I can be sure I am looking at the right diagram in my manual. I do not have the title so I can't go that route so I am hopeing that one of you can help. Here is the engine numbers... K4E044476
