The "Green frame" Ducati 750SS is truly the bike of legends, every year the prices get a little higher, and fewer and fewer examples come up for sale.

Would you like to be able to find the missing engine or frame for an engine or frame that you have? Now there is a way to do that. The Vintage BMW Motorcycle Owners now has an "Orphan List" where you can list your email address and the frame or engine number you are looking for. So you list either the frame or engine number, with the hope of finding the "other" matching part. To view this option, go to https://vintagebmw.org and click on Knowledge Base to see the drop down to Orphan List at the bottom. You fill in the requested information, then there is an approval process to verify your information before it goes "live", to keep the Orphan List in good order. Good luck. Note that there have been successes doing this! Mac Kirkpatrick Glenmoore, PA "After all, what is adventure, but inconvenience, properly regarded?" C. Donahue

Greetings This year when I got my `74 R90S out I noticed the back brakes were weak. Took the rear wheel off and cleaned the brake shoes . Still no better. Adjusted properly. What`s good for cleaning the shoes? Must have gotten some grease on them or something. Don`t want to ruin the shoes Any ideas? Thanks Doug

More re Deves rings: For a Nikasil lined cylinder theirs is a cast ring with a 3 piece oil ring. Mac Kirkpatrick Glenmoore, PA "After all, what is adventure, but inconvenience, properly regarded?" C. Donahue

My cylinders are currently being refinished and Nikosil coated at Powerseal. Powerseal does not carry the replacement rings needed to match this new coating. I would appreciate advice regarding who carries the Nikosil compatible rings I need to finish this work. Thanks, Denny

There are many references now posted online at vintagebmw.org For instance, you can now see the R90S parts manual and owner's manual as well as many other reference materials for other models.

I am finally getting around to addressing a cylinder issue that was not too bad, but needs attention. My 75 SS sat in a showroom for many years on a sidestand, and apparently built up some moisture on the lower cylinder that left a small rusted area. It has burned a little on that side forever, but the power is still there and I haven't fixed it. I now want to fix it and need some advice on how and where best to do this. This takes me back to the Nikosil discussions - what is the current opinion? And where is the best place to get this done? I am about 35 miles out of Sacramento in Auburn CA on the road to Tahoe. Thanks for your thoughts, Denny

"Overall, who makes the best quality motorcycle shocks?” Ohlins shocks for 90S?. What? I quite agree with Mac, with a different approach or point o view The questions are more likely for each of us who ask them selves: -“With what shocks do I feel more secure/safe?” Riding alone? With passenger? Plus luggage? - “What ride or driving level do I have?. Yeah, I have 1 million miles but that does not mean you know how to drive fast and feel difference between Ohlins and Konis or whatever - Do I enter/initiate, “negotiate” and leave long curves at 100 mph?. 80 mph? 65 mph? You just go in and out? - What happens when I touch/ drag my irons-my bike/footsteps on the road while bending curves? - Do I only drive on public roads? Tracks?. Yes, I have done several laps with my 90S on the Nordschleife some years ago plus some more performance tracks since the early eighties so I am free to say not many people, a minority, can say: Ohlins are better than Konis (Ikon or whatever name) or Showas or Better…. If so, it would depend on many variables, i.e., road / track conditions, weight, front forks set up, tires, wind, immaculate frame/chassis, homework done, etc On top, we write on a bike from 1973-1976 which was not so stable….most (not all) of OEM 90S start “dancing" or “bobbling” in long curves from 90/100 mph I think the guy who said that has to ride with me at the Nordschleife, both with a 90S, and then I will tell ya how he runs and if I need Ohlins or not Best Tito Alberto Ayulo Kelly ayulo.alberto@... 649077663 El 3 oct 2020, a las 16:23, Mac Kirkpatrick <drbeemer73@...> escribió: Harold, reference Ohlins products: About a year ago, I came across a person who worked within the motorcycle suspension business for years so I asked him to tell me frankly, "Overall, who makes the best quality motorcycle shocks?" and he said it was Ohlins.

I've been meaning to subscribe for a long time, and this was the nudge I needed to send some money and become a subscriber. I made the $45 investment and enjoyed looking around Snobums resources (I've used his site before while working on Airhead projects), looked through the archived magazines, and reviewed the resources page. When the outdoor temperature goes over 100F today, I'll retreat to my reading chair and explore some more. I forwarded your message to my good friend, John Hermann. I wouldn't be surprised if you are already acquainted with John. John has accumulated over 1,000,000 miles on BMW motorcycles, owned and rode many Airheads, and has photographs of the bikes in interesting places all over the world. His books "Motorcycle Journeys Through the Alps and Beyond" are a great resource for motorcyclists touring in the Alps and Corsica and I have used them myself when riding in Europe. When my wife and I travel on the bike, we often visit John first and ask him for tips and interesting roads near our routes. John is a gentleman, generous with his knowledge, and a wonderful resource. On a different topic, my 1976 R90S is slowly coming together. Forks and brakes are finished. Paint is finally finished. I now need to address the rear shocks. The previous (original) owner installed Fox shocks that are the correct length, but look a little funny on the bike. When I had my R75/5, the rear shocks with the covers squeeked when the springs rubbed the covers and I don't want to hear that sound. Do you have a suggestion?
