I bought a 1983 R100RS in January 2015 just before I retired so I would have a project to work on. At that time, this was to be the RS I always wanted. I fell in love with the RS the first time I saw one in 1977, so what better way to kickoff my new retired life than to own one and restore it.
In 2015, I corrected several problems and did some needed work:
- Fixed a flickering oil pressure light
- Fixed a flickering charge indicator light
- Rebuilt and refinished the carburetors
- Replaced the alternator brushes
- Replaced the broken rubber diode board mounts with metal ones along with the diode board
- Fixed all the cracks in the panniers and welded the broken pannier frame weld.
After that work, I rode the bike for a few months and several hundred miles and had every intent of finishing the rebuild when winter came. But, I got side tracked with some needed refresh work on my 1975 R75/6. And then in early 2016, someone put a first year, 1977 R100RS up for sale. Long story short, I bought it. And then I decided to restore it so I could ride it to the 40th R100RS anniversary rally in Pennsylvania in September, 2017. I posted a couple blogs about that ride and was asked to publish three articles about the build and the ride in the BMW MOA magazine. Of course, I published a lot of documentation about that build here:
So, it’s now March 1, 2019 and I’m ready to restart the build of the 1983 RS. But, I changed direction from restoring it to doing a resto-mod and converting it into an RT. I refer to this as the R100RS/T build project.
I revised my original build plan to reflect the new end-state and I added a video walk-around of the beginning condition of the bike. It’s a whole lot cleaner than when I brought it home in 2015.
I plan to make a number of modifications to improve performance, handling and appearance beyond the conversion from an RS to an RT, I summarized what my plan is in the updated build plan you can find here:
As on all my projects, I’ll continue to add links to how I did various parts of the project to this project build index:
So, stay tuned.
