More re Deves rings:

For a Nikasil lined cylinder theirs is a cast ring with a 3 piece oil ring.

Deves rings were recommended?by Randy Long for this application, ask them for the specific set number. They work great.

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,

I fitted one of these when I was faced with a similar situation.?

?

The cost wasn't much more than I would have spent on parts, machining, Nikasil coating etc.

?

The extra torque meant that I had to fit a heavy-duty clutch diaphragm.?

For the first time in 35 years my R90S burns no oil.

Hey Mac, In a case like Denny's, Can you tell us what the work order should consist of when shipping our cylinders to this company? Do we ship pistons also and they tailor the lining to our original piston diameter? Thanks ?

Denny there is a place in eastern PA that re-coats cylinders. One takes both cylinders and pistons to them, they bore the cylinder oversize then coat it with Nikasil (there may be another but very similar coating), then bore the coating to square and to allow the proper clearance between the cylinder and the piston to allow for heat expansion w/o seizing, etc. Now essentially you will never wear the cylinder out (ok, 250,000 miles depending on use, storage, mx, etc.).

They do it for many folks.

For the PA Airheads Supertech this last February, I got one?of the owners to speak to the attendees and he was very well received. Tom Cutter uses them for instance.

When BMW introduced Nikasil coated cylinders starting with the '81 model year, BMW was able to eliminate the iron insert they used since "forever", and go just with an all aluminum cylinder with the Nikasil coating, which allowed for far longer wear, a tighter tolerance and thus less oil usage, and the cylinder dissipated heat much better because the entire cylinder, being aluminum, dissipated heat far better, so less heat and heat issues.

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

Thank you Mac,

I put Konis on my R75/5 and they were a huge improvement over the worn stock shocks.? Ohlins are great, but they are sure proud of their product!

Hi Harold, some time ago I bought a set of the last of the Koni shocks and fitted a set of original aluminum covers over these shocks. Koni is now out of business, but I hear good things about the company?that evidently bought the tooling from Koni and is now making shocks, it is a play on the Koni name, now Ikon

But I have no personal experience with them.

I run a set of Ohlins on my R90S but I inherited?them when they came to me on a '77 R100RS I bought, so I had Ohlins service them and fit a set of springs for my weight. I REALLY like them but I have not tried to fit the aluminum covers, likely they won't work due to the extra expansion chamber on my Ohlins shocks. But then Ohlins may offer a shock model that will fit.

Good luck!

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 forwarded your message to my good friend, John Hermann.? I wouldn't be surprised if you are already acquainted with John.?

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.?

Greetings to all members of the R90SWorldnet. I started this group over 20 years ago, and you are therefore special?to me as?we have a long successful history together.

I would like to ask the assistance of each of you, in something that is just coming about as we speak; you are the first to know of it, in detail.

The Vintage BMW Motorcycle Owners (VBMWMO) has created a new website, and I invite you to cruise around it, see

It is a very nice website. I am sure you will agree.?

However, and this will require a big leap of faith on your part, we are in the process of creating and enhancing this website such that?it will contain a HUGE amount of information about BMW motorcycles, more than you can now imagine, arranged in an easily searchable format, like no other website anywhere.

A bold statement you say? Yes it is, but we will fulfill that statement; in fact an amazing amount of information is already at a "working" website, being readied for the public's use, and collected and arranged by our webmaster as I write this email.

But we need a GREAT deal more information, in fact, we need *everything* "airhead" that is available, and we want to preserve it at our website, available for easy search by you and everyone else,?for now and especially in the future.

For instance, the Vintage BMW Motorcycle Owners has reached an agreement to preserve Bob (Snowbum) Fleischer's website, at no cost to him and all future maintenance and storage costs will be taken care of. This solved a?very worrisome situation for Bob and his wife Penny, which was how to preserve Bob's tremendous website of BMW motorcycle information, without future cost or work for either of them.

To see Bob's information at our website, again click on the VBMWMO website link?

Click on Knowledge Base, where you will see a drop down menu, then click?on Snowbum's?Encyclopedia, which will open Bob's site. Note the red V of the VBMWMO in the top left corner. Each page in Bob's site now has that logo, signifying what the VBMWMO is doing and that we are committed to preserve Bob's site and all his information, for today's as well as tomorrow's vintage BMW motorcycle enthusiasts.

In the same drop down menu you will see Peter Ardeon's Technical Tips. We have reached an agreement to feature the information at Peter Ardron's UK website in a similar manner, so it is also preserved and available for today's?and tomorrow's BMW motorcycle enthusiasts.

Peter Ardron's?information will also be on our website.

Now this is where we need your assistance, the Vintage BMW Motorcycle Owner or enthusiast, to search the internet, and find ANY information:

At this time, please only work from the /5 to the end of production. So that means model?years from 1970 to 1995.

Your help in this regard would be a great assist in this endeavor and very appreciated! We literally need a link to anything that is in a digital format, so owner's manuals, service bulletins, dealer communications, electrical diagrams, engine oil circuitry, press releases, posters, travel logs, etc., the sky's the?limit.

Think of it this way; in a futuristic way, please imagine, as a future owner of a BMW airhead, what information would you like to see at a VERY easily searchable source, right at your fingertips? So for instance, do?you want to see an owner's manual for a 1923 R32? Click, and Voila! you will see it (BTW we already have that one :-) ?Yes, a LOT of work has already been completed, but far more information and work is going into this!

Want to be dazzled, impressed and see an example of the expertise?and effort that will be used to access this information at our website?

Again, go to the VBMWMO website

Click on Knowledge Base, and scroll down to Genealogy Graph and have a look. It is best if you also look at the Instructional Video.?

THAT illustrates the level of expertise that will be used to create this information and tie it together in ways that will amaze you, I promise!

SO, if you would please, search the internet and email to me, Mac Kirkpatrick at

drbeemer73@...

WITH A SUBJECT OF "LINK" *only*

ANY and ALL information you can find about the 1970 to 1995 BMW motorcycle models, that being /5 to the end of airhead production.

You will be helping a very worthwhile effort, you will not believe the outcome,?AND YOU will have helped create it!

Thank you,?
