    This manual was prepared from a photocopy of an original Ducati 750 workshop manual provided by Dave Gooch. I'd like to thank Dave for generously agreeing to making this information available to the Ducati Bevelhead community.

    Manual scanning and html coding was done by Willy Gonnason. It is my desire that this information remain freely available on the Internet to people interested in Bevel Head Ducatis.

    Since the quality of these pictures suffers from limitations of my scanner, I suggest that you contact Dave (North America: 519.869.8304) for a copy of the original manual if you need this information for any serious work. I would also caution you to take the dimensions for valve clearance printed on page 77 of the original manual with a grain of salt if you are reading the English section; the values listed in the Italian and French sections are the correct values.

    Note that the company Ducati Meccanica has been bought and sold twice since the machines described by this manual were last manufactured. Many thanks to the members of the original company that produced these machines, and in particular, Ing. Fabio Taglione for designing and helping bring these machines to an appreciative audience.
