The Guzziology book by Dave Richardson is full of useful information about repairing and maintain Guzzis. However with over 800 pages the plastic binding comb (GBC) is at the max.
The most common failure of the comb is one or both of the end teeth to break off or rip open the capture hole so the binder can't stay closed. After that the pages unravel. It's tedious to re-thread the pages into the comb but that only works until the book is reopened then they unravel again.
