Hello.
Bought the book from Spain, and there is a difference between this book and other workshop manuals: it is full of tips and tricks written by a person who has disassembled and assembled LOTS of these bikes, opposed to the other books, in which someone writes about complete teardown of a single bike, not detailing the typical problems that these bikes have after 30 or more years. I own a K8 with a F2 engine on it, and a K7, so I vote for a supplement for F2/K7-8 bikes, which, especially the F, have their own tricks and tips.
