We'll I recently aquired my fathers '52 R67/2 and '78 R75 unfortunately it was threw his passing. He wasn't a computer guy, but there might be someone here who he's met over the years (Dean Lyon).

I've been into BMW's for 20 years but they were all cars, so I'm diving in to start learning these bikes. I orderd an R67 reproduction manual on ebay and was directed this way.

As of right now the R67 is in need of a transmission rebuild, not sure if this is something I want to tackle or should tackle.

Anyways just saying hi and here's a few pics. And yes the front-end of the R67 isn't stock which maybe frowned upon by some.

The airhead has some nice stuff on it. Looks like ebc pro-lite rotors, ohlins shocks, flatslide carbs. Is the front end stock on that?

Not sure on the fork, I will have too investegate. It's also got an 800 motor and another huge fiberglass tank (Heinrich maybe? will post a pic) and a dyna III ignition. I just drained the gas and gave it some fresh ethanol free gas, changed the plugs and adjusted the carbs a little and it runs strong.

So I've been doing some cleaning and digging around it appears that it's converted to 12 volts as it says 14v 13a on the Bosch Alternator? part# 0 120 340 001. It also has what appears to be an updated points plate that I've seen someone sells. So I guess I'll be buying a 12 volt battery.

Any insight/pointers of what these pictures show

You have a magneto system AFAIKT...the yellow blob is the magneto coil. I don't know if they can be 6v or 12v...my guess is it's 6v.

The points plate is the Pentacomm system invented by Dr. Harms, designed to allow you to set the points gap while the engine is running. The stock system requires that you shut the bike down, make adjustments, then restart and check the new settings. The Pentacomm system also lets you use a more common set of points rather than something specific for the /2.

Ok great, so stock ignition with updated 12 volt system for lights.

Thanks!

So what is the deal with that alternator? It looks like a post '74 unit?

I'm assuming my father had an early 12 volt conversion done at some point, but don't really know all the details. I'm just being very cautious because I don't want to fry something up

I just sent out the transmission to Brooks Motor Works in Olympia, WA to get rebuilt, so hoping to be riding this spring!
