Welcome from rain soaked Indiana.
Get factory shop manuals, take a good series of before pictures, and start taking it apart. When I started reviving my 78 750K8 it was the first bike since 1967. Being my first attempt I had no clue, but I just labeled things as I took them off, have a good friend who has a K7 and has helped me a lot. CycleRecycle is here in Indy and has been good for advise and some parts. The guys on this forum have mountains of knowledge. Don't be afraid to ask. Check out the tech section for FAQ's.
