From left to right, they are:
5. 1975 R75/6, not very complete. Just a month younger than Ernst, 600ish serial numbers difference.
4. 1979 R100RS, almost complete. Possibly a few parts missing in the intake tract.
3. 1979 R100/7, very complete.
Both R100s have interesting period mods. They both have San Jose BMW upper triple clamps, fork braces, and shocks. The RS has a reinforced swingarm. The /7 has air caps on the fork.
The /7 has some mods to the motor. Lockhart cooler and twin plugging are the obvious ones. There were some notes regarding the heads found under the seat along with the old registrations. It looks like they were modded at 28,000 miles to deal with a light pinging complaint. They may have been ported and polished.
I expect I'll be starting with the /7 this winter, after Ernst gets his heads back on. I'm calling the /7 Edgar.
Here he is:
When I first saw the tiny pix on my phone, I thought 'Windjammer' but I don't think that's the case. Here are a couple views from inside:
That little knob is a headlight angle adjuster.
It also has a gaiter flap and there's enough room inside that the turn signal posts clear. Most fairings need them removed or bent out of the way.
Here's the cooler:
Anyway, thanks for checking this out. I expect things to move at my usual glacial pace. I hope to be touching wrenches to Edgar soon after the new year.
