Vintage BMW Motorcycle Owners

Good progress this weekend. The electrical system is going in fine. The only glitch so far is not having the turn signal wires routed before I put the front end together. Grrrrr. The body work is coming together. Im really happy with the progress and hope to have more to install when I get back from...

I've not run the VR1 but I understand that it is recommended by Vech. I tested nearly 20 different brands of oil about 5 years ago. VR1 has a good amount of ZDDP included. The best oils for ZDDP were Golden Spectro 4 and BMW's oils. I've mostly run BMW oil in the past 8-10 years, but now BMW is no l...

1975 R90S Its time for fluids. Sensitive topic I know .... so lets not go there. Im just curious what everyone is using. I run Valvoline VR1 20-50 in my R60/2. Its a popular go to oil for vintage and antique bikes for various reasons. Is anyone else running it their /6's? For tranny/gear oil .... I ...

Also the new shaft bolts are different and do away with the lock washers. Some of the locks have broke, so they recommend using the new stuff. Work and ...

I have been on vacation so progress has been slow. However, this morning I was able to install the engine. Soooo much easier without the transmission attached. I assume the tranny will go in easy peasy right? Anything Im missing here?

Now its back to work and the R90S sits for another week.

Looks great. That should clean up very well.

If you want to do your own air cleaner this is how I did mine. Im very happy with the outcome.

Yesterday when I was cleaning my 75 R90S engine I discovered the same thing. I do not have the numbers in the box but I do have an "R" on the other side in the same area. So ... 235243 June 1-7th of 1975 is week 23. My ID plate is stamped June 1975. Makes sense. VIN decoder verifies it. Wh...

My guess is they will be on eBay for a long long time at that price. bobsbmw too. Wow. Ridiculous
