I have been delinquent working on this project for a few months. I got distracted with preparations for riding out to the 40th anniversary rally for the R65LS-R80G/S and then, I was lazy when I got back.
Below is my documentation of this work in write-ups and short videos.
NOTE:
I edited the Remove Clutch video and reposted it on YouTube. If you use the older version of this blog, the link will fail. I edited the link below so it points to the new video.

When parts arrive, I’ll get the back end of the engine buttoned up and, as is my affliction, I will write-up and film the corresponding documentation.
Here are a couple of pictures from the documentation.

Hello Brook,
My name is Mark and I live in UK. I am currently restoring a 1978 BMW R100RS. I am having real problems setting up the clutch, and trying to understand the correct method.
At the moment the clutch seems to bite almost when the handlebar lever is fully out. From what I read in my 2 manuals it should start to bite at about half handle bar position. I have ordered a new clutch cable and gearbox clutch lever arm from Motor Works in desperation. Any pictures / videos / advice would be fantastic.
Regards,
Mark
Hi Mark,
Here is the link to the procedure published by Tom Cutter at Rubber Chicken Racing Garage. It is what I use and it has worked well for me.

Hi Brook,
I followed the Tom Cutter clutch adjustment procedure and it now functions perfectly.
Many thanks,
Mark
Mark,
Cool beans. I’m glad that procedure removed your problem.
Best.
