Greetings all. I am interested in doing the final drive service on the R12 myself. I searched youtube but only found a vid on a GS. It appears to have a bit different final drive setup than the R. I am not particularly experienced with mechanical stuff, but am able follow directions well enough. Any advice or vids/pics any of you can provide would be greatly appreciated. Maybe this is a job left to a Beemer dealer technician? Thank you for your time.
