servicing and maintanence schedules

I have recently taken the rash decision to do more work on my bikes myself. Where can I get hold of reliable info on the serviing intervals and what needs to be done for Beemers? Specifcally an 1990 R100GS. I have a CLymer manual - any other source of information better than that for my bike?
