These manuals come from various sources: these are usually indicated in the "properties" of the file.
In the file name:
- the suffix "PL" indicates that it is an Parts List Manual
- "mmaaaaa" or "mmaaa" indicates the month and year of the edition if possible
- the language is sometimes indicated (I = Italian; GB = English; F = French; D = German; NL = Dutch; US = USA)
For reasons of commercial piracy (pdf files for sale on E-bay) while they are graciously made available by the website (just like the files available on Anima Guzzista or Morino for monos), the managers of the Moto-Guzzi.it website from which some files are available here, have locked their files and added a watermark; this should prevent some from getting blushed by web borders or other bike fleets that sell free things....
As far as I'm concerned, since I don't have time to watermark the documents, only a few of them are locked and have a particular footer.
Many thanks to Anima
Carlo Morino, Guzzitech.com,
(Bolzano), Paul (Nederland) and so much others !
PA versions maybe usefull for Civilian motorcycles because manufactured untill 2001.
Note about engines with Ducati alternators: there is an error on all the Parts Lists concerned on the "Generator" drawing. Behind the rotor are 2 parts, a spacer and an O-ring. Unlike exploded parts, the O-ring is behind the spacer (not in front).
See too the website of Renato and his Documentazione Tecnica !
