Most of the above diagram links are model generic diagrams from the published Clymers K bike maintenance manual.
If they are not what you are looking for(or not detailed enough), I have the official BMW diagrams available for most all of their bike lines thru 2008 model year.
Available in the following languages.
German

Message me with a request of what you are looking for(and language) and I'll see what I can do for you.
There are way too many options to post them all on here.
