Andy, I used my haynes manual for the 1200 for the first time this last weekend, I found it to be crap. As an example in the section for tappets it does not give you the settings, you have to go to another section for all settings, ok easy...but with greasy hands...etc. I'd expect to get all the info I need in one easy description. Then the actual description of how to get the piston to TDC is ambiguous, ok for me cos I've worked on many bikes over the years, but the whole point of a manual is to help novices.
Frankly the best help I have found is the info pages of site like this and ADVrider, these are concise descritions writen by riders who have done the work thenselves and often do it without the expensive BuMW special tools.
I remember Haynes manuals being great when i was a kid, now they seem to assume you are a mechanic tio start with..IMHO
