R50us sitting

[Cliff]

I just got a 1969 R50us that has been stored indoors for about 15 years. It turns over and has oil in it. I thought I should drop the oil pan for inspection, change the oil and check the head bolt torque. I also thought I should change the other fluids after I get it started. Any other sugestions on what I should do before starting the motor?

Was it inside a house or a garage? If the latter, I would take off the front cover and air cleaner cover to see if anything crawled in and died or made a nest. Adjust the valves, look for debris or slurry in pan and add a magnet to catch ferrous bits. Not really too much else to see up in there. Do you know about slingers?

Thanks for the reply, I am new to the forum but with now that I have the R50 I plan to contribute when I can. The bike was transported to me so I don't know how clean the storage area was, it was in a shop and it seems like it was dry and fairly clean. I guess I should look in any accessible passages. I have been following the slinger posts but I am not sure how to clean/replace it. Is there an article I should read?

Go to Duanes website and read up a wealth of information: http://w6rec.com/duane/bmw/index.htm

I don't recall seeing a "how-to" on slingers. Vech discusses slingers and their importance here:

Dan at Cycleworks sells a many-in-one tool that is used to take apart the engine:

IMO, this is a job for a professional. There's some experienced needed to understand what you're doing, how to evaluate what you pull out of the engine, and how to put it back together. I chose to disassembly the entire engine of my R69S but left the crank, cam, and flywheel intact. I then handed that to my mechanic to do the "heavy lifting". Hopefully that saved me some money and got my hands dirty with a better understanding of the workings of the bike.
