Vintage BMW Motorcycle Owners

Today we cracked open the engine. At 50K miles we discovered the original clutch was still installed and no one had been in the bottom. All the bolts and screws were fresh and like new. Both slingers were close to 50% full but no where close to causing any issues. At 55 years old some of the bearings needed some help but they all came out without any issues. Still very happy with everything.

If you decide to use the original style barrel bearing for the rear I have a couple NOS German and Italian ones I may sell. Have fun and buy all new parts! Bearings/valves/slinger/pistons/etc. unless the pistons are like new. You'll just cry once.

Thanks for the offer and advise. The heads, cylinders and crank are all out for rebuild. Everything will be "new" going back in. Definitely using the barrel style bearings.

Im currently gathering all the parts for paint and Powdercoating. I hope to have everything dropped off in the next week or two.

Enjoy the process,pay close attention to ring gaps,valves/ valve seat sealing,and timing. I learned the hard way,but now have 4 vintage BMW bikes that start on 1 kick and drive beautifully! I love my R69S, most exciting bike of my little collection, you will love yours!

Its been slow so I tackled the front and rear brake drums.

Its good to see that you didn't find what I did when I dug into my barn find R 69S. The front slinger actually melted, expanded and caused the motor to lock up back in 1975.

Yikes.

Jeff gets the reward for engine in the worst state. That is absolutely incredible that a machine could run long enough to get to that point!!! Jeff you did a great job resurrecting her.

Thank You! This is the rescue as it was close to being completed. A few up grades and a nice Turf Green finish and it is ready to ridden "hard and hung up wet" again. NOT!!!!

I have a 1967 R69S which I bought in pretty rough shape in 1978 (IIRC) and put a fair amount of work into. I rode it from Chicago to Nova Scotia and several rallies. In 1985 I put it into storage to go back to school. Life got in the way, and the bike is still in storage though considerably disassembled. I'm approaching retirement and want to get the bike back into road-worthy condition. I am pretty sure the engine needs attention to the oil slingers, and I am not sure this is within my capabilities. Is there anyone in or around the Chicago area who could service the engine, or at least give me guidance? I have removed the transmission and dismantled the cylinders in the past so I have some mechanical abilities.
Thanks for any advice!
