Snowbum is also known as Robert (Bob) Fleischer,  "The Expatiating Scribe of the Sierra")

Our bikes are getting old.  You can NOT rely on just any BMW dealership for repair work, nor for the proper parts and parts numbers.  Dealership personnel may well NOT have the proper knowledge nor background.  DO consider independent repair centers, especially ones that participate on LISTS and FORUMS. 

BE CAUTIOUS!  ABOUT WHERE YOU GET WORK DONE, WHERE YOU PURCHASE PARTS, EVEN FROM BMW DEALERSHIPS!  CHECK MORE THAN ONE SOURCE FOR INFORMATION, PARTS, AND WORK.  BMW sometimes has incorrect part numbers, and sometimes ships the wrong parts or poorly made parts. Be careful when ordering from companies, foreign or domestic, that may not be selling genuine or REALLY equivalent BMW parts.  BMW has published ERRORS!  These published errors get compounded when re-published, by such as Clymers or Haynes!  In some instances I DO have "corrections to Clymers or Haynes, etc" type of information on this site.

I DO recommend certain shops, and individuals, upon request.  Especially see my pages 78A and 78B, below.

Regarding section 38B onwards to the end of 38x:  
I have obtained schematic diagrams posted on this website from a variety of sources.  NONE are from the Chitech BMW Electric School Manual, as you can purchase that manual (which covers 1955 to 1990+).   Many full schematics in it are fuzzy but I DO recommend you purchase that manual, see my URL page for how to obtain a copy.   That manual is almost a must for Airhead owners.  There is a critique, with some corrections, that I made for that manual:  chitechelmnl.htm

I PROBABLY HAVE every schematic diagram for every Airhead (& most other models), but some need interpretation.  My collection includes (probably)all of the World's versions, so there are literally HUNDREDS of diagrams,  including accessories ...such as the early Airheads when they were available with Avon fairings!  Diagrams includes those for heated grips, special lighting, & Authorities (Police) models.    There are a LOT of similarities between various models.     Quite a few of these schematics are already on this website.

If you need to contact me for a specific diagram, or perhaps something is not clear to you in a schematic on my website, ask on the Airheads list or K bike or ibmwr.org tech-list first.    When you post to a LIST, I would like to know if you want a schematic for the main frame diagram, or engine or some sub or accessory item.  I need to know your BMW model, its year, and if it is a USA or Euro.  It would be very helpful if you knew the model code that BMW uses for your motorcycle.  If you do not know the model code, furnish the full serial number or VIN number.  ONLY if you are not on one of those LISTs (and I may reply with WHY NOT?) should you directly contact me at:    CLICK!  
Keep in mind that personal inquiries to me take up not only a lot of my time, but they benefit ONLY YOU; while answers on a LIST benefit all members of that list.

Sometimes questions you may have will be answered by referring to my electrical hints article #15, or some other article in the Electrical section of my website.

Regarding AIRHEADS electrical schematic diagrams:
The R80G/S is similar to the R45, R65 and R80ST. 
The R65, ST, GS & G/S type of instrument pods will be similar, or nearly so. 
The same or near year of a RS and RT may be identical to each other. 
The R75/5 will use the same diagram as a R50/5 and R60/5. 
The R60/6, R75/6, R90/6, R90S  will all be very similar. 
The /7 is somewhat similar to the last of the /6 series.
The /6 and later with the early style-type of pod (pod NOT like the R65, ST, G/S, GS)
will generally have those pods in common; variances are noted in my website.

In general, a lot of the wiring and circuits for 1970 models are similar to even 1995 models!  

This same sort of schematic similarity is found on Classic K bikes.

        http://www.powerboxer.de/Schaltplaene-fuer-Boxer.html 

       Keep in mind that these are GERMAN schematics, not necessarily for your USA
       or other non-German-shipped country bike.  Use these schematics in
       conjunction with what you find on my website. There is a LOT of information
       besides schematics on this German website.

8.  Death Rattle:  Does your 850, 1100, or 1150 Oilhead, 1994-2004, make an
     uncomfortable-to-hear rattle upon startup?  Hexheads too!
         http://www.mklsportster.com/Articles/mcncct.pdf
      Article describes the fix, with photos.  The rear-view engine cut-away
      photo is a REAR-view of an Oilhead motor. The Hexhead tensioners are the
      same.  Note that the left tensioner assembly is located on top of the cylinder,
     "facing" downward, in a position that allows oil to drain out of the tensioner
      sleeve during shutdown. The right side tensioner assembly faces upward from
      the bottom, and IT remains full of oil during shutdown. This is why the
      tensioner that is typically repaired is the left side one.

NOTE!....Some of my Airhead articles are informative to K bike owners.  Examples are the References article (78B), which has information on driveshaft rebuilding and resources for many things; articles on the ignition, brakes, front forks, ETC.  Many other examples of useful articles in the Airheads sections.  Scattered in this long list of Technical Articles you are reading are stated references to Airheads articles that also apply to Classic K bikes, but I have probably missed a few. I suggest you look at the entire list of articles, and see what might apply to your Classic K bike.
