Hey John! We would love to get help fleshing out our device database! Unfortunately for us, our photo table is pretty small, and we don't have a lot of motorcycles to experiment on ;)
However! We've had some really amazing do-it-yourselfers like @nsiemsen make some incredible guides on the larger mechanical devices we haven't gotten around to. Check out the [https://www.ifixit.com/Device/Mercedes_W123|Mercedes 123 repair guides]!
If we can get users like you, and more computerized-bike-savvy users too, to contribute, we could all learn a lot from each other. Plus our images stay hosted way longer than most forums!
