Ken was great!

Indeed, a curious one. I've got five different forks from 1975 to 1979 here at the house and they're all consistent with your left side.

In this country, there was often summer gas (E0) and winter gas (E10), particularly in urban areas. This was to give everyone a lean mixture in the winter time to reduce carbon monoxide emissions. Mind you, this only really worked on carbureted vehicles. Fuel injected vehicles (at least the 99% of t...

Yes, I'm at two odometer failures now. I've got a guy who fixes that problem, restores the housing, and recalibrates the speedo so it's within 3% of actual, instead of reading 10% to 15% high. Old stuff doing old stuff things!

My 1978 R100/7 has some vibes under load under 3K rpm. But I'd also found that it doesn't charge consistently under 3K rpm--when my son was a new rider I was shifting at 3K to keep him in the mirrors. This eventually drained the battery. So for both those reasons things are much better over 3K rpm. ...

Look at the red wires that meet under the starter relay. One of them may have intermittent connection. Basically BMW feeds the whole bike through the starter relay. One red wire comes in with power and the other one goes on to power everything in the headlight. The wires go to separate, but connecte...

I've created a bit of organization in my shop. I saw this idea in a high-end car collector's garage and my ambition rose to meet the idea: https://photos.smugmug.com/Shop/i-bTRsXjS/0/NGTtr9DJjp9qwCNnhfNrWMxddsvk3xCrcpFh6ZnwJ/L/ReferenceBoard10082025-L.jpg Mine is about half the size of the one I saw...

Yes, I use 250cc per leg in my 1970s /6 and /7 forks. I don't drain and refill--if I'm replacing oil the fork came pretty completely apart.

My bikes run just fine on E10 but they don't like sitting with it. When I lived in California and could only get E10, if the bike was going to sit for a while I'd park it with a full tank and Startron fuel stabilizer. I always run the float bowls dry when I park the bikes. I had good luck with this ...

Additional pro tip for the Mechanic From Hell wedgie technique: Have the reservoir nearly empty before you push the pistons back as the act of pushing them back will move fluid from bottom to top.
