Outlaw, I have a KZ750 twin, 1979. I looked all over the place to find a manual. In fact I just yesterday sent the money order to get it. You might try E-Bay, but I tried 4 different times to get one and got out bid every time. I won´t even tell you how high my bids were, just that they were really too high. Most dealers will tell you to try Clymers, but as I´m sure you already know they don´t have one for the twin. I´l offer any help I can give you, even try to send what you might need over e-mail. Let me know.
