Internet mailing LISTS and websites:
Your query may well help others... PLEASE post technical inquiries to the appropriate LIST, below.
If the message is very personal. you can contact me at: CLICK!

******If you are new to Internet Mailing Lists, and especially if new to BMW motorcycle riding and BMW motorcycle people, please click on this line and read the short article!!******

I very well may tell you to "take it to the LIST!" if you contact me directly, without a very good reason for doing so.  That way, answers benefit more than just you!
Taking your query 'to the list' also GREATLY reduces my E-mail hours.  PLEASE use the LISTs!!

You CAN get advice from Snowbum, and many others, on the various LISTS. 
Snowbum monitors and participates on about 6 LISTS (mostly on the Airheads List); the SCT sidecar List, the K-BMW List, Tech LIST (IBMWR), USCA-West List

If you own a BMW Airhead motorcycle, you REALLY SHOULD join the Airheads Beemer Club CLICK

Airheads CLUB website:   http://www.airheads.org


THE major sidecarist's LIST http://autos.groups.yahoo.com/group/SCT   Snowbum IS active on this LIST.
There is an off-shoot of that sidecar list, for those in the Western part of the U.S.A.  That list can be found at:
http://groups.yahoo.com/group/USCAWest/


If you own a Classic K-bike (K75, K100, K1, K1100), you should join the K-bmw mailing LIST.
Snowbum is active on that K-BMW LIST:
http://autos.groups.yahoo.com/group/kbmw



Other's:

Airhead, K-bike, Oilheads, ETC.        Lots of technical stuff:     http://IBMWR.org

Oilheads, Hexheads, Camheads, K bikes:  http://bmwsporttouring.com  (snowbum does NOT monitor nor participate here)
 

 

  Please send questions to the Airheads or other appropriate LIST, so that answers benefit more than just you!   

IF you have posted to a LIST, and have not received the technical response you need after 3 days, 
THEN you MAY E-mail me directly, and I may (or may not!) try to help you.  Your query may well help others,
which is why a LIST query is PREFERABLE!   SO, PLEASE  first post technical inquiries to the appropriate LIST.  

This is particularly so for Airheads and Classic K bikes, where Snowbum is VERY active.
I am likely to ask if you have posted there first!

If the message is "very personal", you CAN E-mail to me at:    CLICK!
(you'd better have a really good personal reason!)

******If you are new to Internet Mailing Lists, and perhaps if new to BMW riding and BMW people, please click on this line and read the short article!!******
******I have added information to this article recently******



Airheads (Snowbum's primary interest):

There are many sources for information.  The Airheads LIST is best for immediate information on Airheads.
 
You can subscribe to the AIRHEADS LIST by using one of the two following methods:
(Subscribe using your normal E-mail address as the sending address).   

Method #1:  Using the computer that you intend to use for E-mail to and from the LIST, send an e-mail message to:   
airheads-request@micapeak.com
     In the Subject line area, leave it blank.    In the Message area, simply put:   subscribe airheads Xxxxxxx  Xxxxxxx
Where Xxxxxxx  Xxxxxxx is your name

The server at Micapeak will do all the rest, as it automatically picks up your computer-generated return address.
The server is set to accept plain text OR html; and the server will automatically strip any html content, and convert
your message to plain text.  It is best to NOT send HTML or images to the LIST as they are stripped-off by the Server.

Method #2:  Go to the following URL and follow directions: http://www.micapeak.com/mailman/listinfo/airheads
 

AFTER you subscribe, you will get a response from the server at Micapeak.  

 You will probably NOT want to use the Digest mode, it can be a hassle, and much less
 helpful than you might think, and it can require you to do MUCH more editing, in order to reply to messages.
  

Put  airheads@micapeak.com  into your computer address book, perhaps using a nickname such as "Airheads"; so you
don't have to type the full address when YOU post an initial message; most E-mail programs can do this.    You will post and
receive mail at  airheads@micapeak.com. You do NOT post mail, only commands, to  airheads-request@micapeak.com
(or, to the micapeak.com mailman URL) 

Want more information on the Micapeak.com mailing lists...etc., such as how to find the LIST archives, how to
search the archives, and even how to find other micapeak.com ...or other....mailing lists; set options? set passwords?
 www.micapeak.com/mailman/options/airheads/

To see all the Micapeak mailing lists and to sign onto any of them:
www.micapeak.com/lists

Here's a list of all the mailing lists on the internet dealing with motorcycles:

Micapeak has archives:

Caution!!  Airheads LIST archives dates, particularly before the mid or later nineties, are suspect!!!

Copyright information!

MOST of the articles on this website are copyrighted.   ALL ARTICLES WRITTEN BY ME AND LISTED ON THIS PAGE, OR OTHER PAGES, ARE COPYRIGHTED (unless otherwise noted).  You are granted use for yourself, printed or electronic copies.   You are also granted approval for incorporation by reference or hyperlink, to my articles for many other uses.  You must not abridge, modify, shorten, or otherwise edit my articles, unless it is made clear that that you are doing so, and you MUST prominently note any change in INTENT, or INFORMATION.  You are NOT granted permission to DUPLICATE my articles, in part, or entirety, without prior permission from me, except as above noted.   Commercial duplication; or, editing and publishing in any manner the content or part-content of my articles; and/or failure to quote me as the source/author, use of plagiarism, etc.; including sale or other commercial activity, beyond what is specifically herein allowed without specific permission, will result in public announcement of same, and may result in prosecution under the laws of the United States.  I'm VERY protective of MY articles...but I will usually grant you usage beyond just for yourself...so ask!  You do NOT need my permission, if you follow the preceding, to use my TECHNICAL material in many ways,  but if you have any question, you may e-mail me.   e-mail 
One of the things that REALLY ticks me off, is misquoting me; and even more-so, is modifying my articles, or parts of them, and then claiming them as YOUR work.  I WILL pursue you, LEGALLY!  for damages!

On purpose  I don't make money off my articles (except if someone clicks on a Google Ad-Sense advertisement), and I don't want you to.  

NOTE:  If you have a website, and your page where you have placed something from MY website (or a hyperlink to my website, which is always appreciated!) has Google Ad-Sense advertisements (or similar) that can pay you some income if folks reading your website click on those ads, I DO NOT consider your webpage to be commercial use, so I do NOT restrict your use of my material on such a page, so long as your usage is within the rest of my guidelines!

CREATIVE COMMONS are two words that describe a way for a copyright holder (that is ME, folks!) to grant YOU permission for MY WORK to be copied, distributed, or adapted...if....IF!....certain conditions are met, that is, 'Some Rights Reserved'.     So, to keep this simple:  You may use my work if you keep my name with it, and you LINK to my original work, and modifications by you are noted.  You may use my material for ONLY non-commercial purposes, unless you have MY permission.   Creative Commons does NOT grant you unlimited rights; in many instances you NEED APPROVAL FROM ME.
 


DO  keep  in  mind  that  I  frequently  update  articles  on  this  website!! 

This is important if you used a search engine such as Google, ETC, because they will save pages on the date they scanned
them, and they do NOT update pages until they are next scanned; and who knows when that is. Usually an older scan is
listed as 'cached'; but, the main clickable link search results USUALLY...but not always... takes you to the existing
current page.   It is best to go directly to this website. I suggest you bookmark (Favorites) the HOMEPAGE, and
not the page you are looking at right now.
  The HOMEPAGE is technically called the INDEX PAGE, and it is: 

http://bmwmotorcycletech.info   

 BOOKMARK or set as FAVORITES, THAT page. That homepage has a DATE of revisions, so you will
know if any revisions have been done to the website.  
I always issue a revision date when an
update is substantial.  Revision dates are listed at the bottom of the particular article AND
on the Technical Articles Index page; and  the homepage will also have the date.  
There may be dates on the Homepage and Technical Index page at the bottom,
that refer to the last editing.  You should ignore that date.

Another reason to Bookmark (Favorites) the Index homepage and not the
technical articles index page is that the main index page (homepage)
contains access to things NOT on, and NOT accessible, from the
Index of Technical Articles index page you are now looking at.


Errors or omissions on this site should be reported to me, and
are welcomed.  That includes helpful comments!
(Even UNhelpful comments!)
(except complaints about fonts and colors and verbosity!)


 

 ©   Since ALL Technical ARTICLES ARE Copyrighted!! (unless specifically so stated), reading and
use beyond this point constitutes an implicit acceptance of my terms and conditions!!!


This website is primarily about BMW Airheads and Classic K bikes; with a bit of Oilhead information thrown in and a fair amount about sidecar rigs. 
Our
bikes are getting old.  It is my opinion, based on considerable experience, that 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. 
BE CAUTIOUS, CHECK MORE THAN ONE SOURCE FOR INFORMATION, PARTS, AND WORK. 
BMW themselves sometimes
 screw-up part numbers and even ship the wrong parts! BMW has shipped poorly made parts now and then! 
Be cautious when
ordering from companies, foreign or domestic, that may not be selling genuine or REALLY equivalent BMW parts.  
BMW has been known to publish ERRORS!  Those published errors get compounded when accepted and
re-published, often reworded and wrongly so!...by such as Clymers, or Haynes!...and you will not find out
about any corrections for Clymers and Haynes unless you ask  on one of the E-mailing Internet LISTS!
 ...in some instances I DO have the information on this site.

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

"There is always a greater idiot."

 Make something idiot proof and you will eventually see a demonstration of this saying.

A common mistake that people make when trying to design something completely foolproof
 is to underestimate the ingenuity of complete fools.


"The measure of a man's character is what he would do if he knew he
never would be found out." - Baron Thomas Babington Macauley

"An expert is someone who has made all the mistakes which can be made,
in a very narrow field." --Niels Bohr

"...You cannot prove a vague theory wrong. Also, if the process of computing the
consequences is indefinite, then with a little skill any experimental results can be
made to look like the expected consequences." Richard Feynman, 1964

There are three kinds of men:
The ones that learn by reading. The few who learn by observation.
The rest of them have to pee on the electric fence.
- Will Rogers

"We have all heard that a million monkeys banging on a million typewriters will
eventually reproduce the entire works of William Shakespeare. Now, thanks to the
Internet, we know this is not true."
-Robert Silensky

"There is no practical reason to create machine intelligences indistinguishable
from human ones. People are in plentiful supply. Should a shortage arise, there are
proven and popular methods for making more."

Under democracy one party always devotes its chief energies to trying to prove that the other party is unfit to rule--and both commonly succeed, and are right...
-H.L. Mencken

A few (??) words about schematic diagrams in the following sub-sections 38B, ETC:   I have obtained the schematic diagrams posted on this website from a variety of sources.
I have NOT taken any from the Chitech BMW Electric School Manual, as you can purchase that manual (which covers 1955 to 1990+), AND, many
schematics in it are fuzzy. I DO, highly, 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 DO HAVE, to my knowledge, every schematic diagram for every Airhead (and some other models), but some are fuzzy or otherwise unclear, some
need interpretation, and my collection includes all of the World's versions, so there are, literally HUNDREDS of diagrams.  BMW even made diagrams
for the various add-on accessories....that included such as the early Airheads when they were available with Avon fairings!  I have put a representative
diagram for all models up to about 1984 or 1985, on this website.   There are a LOT of similarities between various models, especially some of them.  
Try using the diagrams on this website with each other, as you may find that helpful.  

My files contain schematics of all sorts of accessory items including Authorities models.   If you need to contact me for a specific diagram,
You may be asking about some esoteric point, or something not clear in a schematic, etc. 
Ask away...but on the Airheads LIST or K bike LIST first. 
 I will need to know if you want it for the main frame diagram,
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.
Contact me at:    CLICK!


I would appreciate NOT being contacted for any specific diagram or comments upon such, until you FIRST HAVE LOOKED at these 38B+ diagrams and have specific
questions that are not answered by them.  Besides the BMW diagrams, I have some for various aftermarket items (such as fairings), etc.      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.
 

MORE....Regarding electrical schematic diagrams:
The R80G/S is similar to the R65 and R80ST.    Models with the R65, ST, GS & G/S type of instrument pod will be relatively or exactly similar.  
The same or close 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....all will be very similar. 
The /7 is somewhat similar to the last of the /6 series.
The /6 and later with the earlystyle-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.
 

 

****Here is a link to a German website, that has a LOT of Airhead (and some R1100 oilhead) electrical schematic diagrams.  
     Click on the Shaltplan, shown in red, for your model:
    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 below, on my website. 
There is a LOT of information besides schematics on that website!

     Read this:   http://www.mklsportster.com/Articles/mcncct.pdf
    
That 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.

14-b.   If you are having ABS codes problems, before you jump to conclusions, remove both ABS relays, clean contacts
            and clean the relay connection spades too, and add contact cleaner to them.
  This is good advice for the ABS main
            computer plug connections too.


15.      See Oilhead section, above, item #5, on the Hall devices.....that article has information applicable to the K bikes.   See my ignition.htm article too.

16.     Adjusting the steering head bearings on a K75, K100, K1100:  
http://www.largiader.com/bearings

17.     Brake light switch problems....see article well above, #37B
           If you have a 1985 K bike, and a stiff throttle, also read that article 37B...yes, a brakes switch article!

18.  
Hyperlink to a forum-type website.  Mostly on Oilheads, but some Hexhead, Camhead, K:   http://bmwsporttouring.com

19.   Locks, gas caps, KEYS, etc.......I have an article, #75, above, that covers all this in some depth.

20.  See Airhead section article #30 regarding the ignition circuitry, lots of useful information on the Hall element, etc.
          note also, that the following article, while for a R1100RT oilhead, is very useful for K bike owners:
            This
article, which is illustrated, is about replacing the hall sensors for a R1100RT sensor repair, and is SIMILAR for a K bike:
            www.ebbo.org/2av54.php


21.   Doing a rear main seal job is involved.   Here is a video of the procedure to R/R main seal on a Classic K bike.
        Useful for anyone wanting to know what/how in taking apart the bike....even if not doing a rear main seal job.
        http://www.youtube.com/watch?v=Kx3mVne8Q-Y
        It is in GERMAN for the audio. The mechanical support for the bike is flimsy in MY opinion.
        They found one of the headers broken....in case you wonder about the exhaust pipe being 'shown'.

22.    http://k100rt.aforumfree.com/ has a lot of information for Classic K bikers, NOT just the K100.   Many service bulletins
        are also on this site.

23.   http://www.flyingbrick.de/  has a lot of information.  It's in German, but very useful, and has all the wiring diagrams for
        all the Classic K bikes (K1, K75, K100, K1100, K1200), and lots more.  Wiring diagrams are under Shaltpläne.

24.   How to replace an oil level sight glass




NOTE!....Some of the Airhead articles will have information pertinent to K bike owners.  Just ONE example
might be the References article
(78B), which has information on driveshaft rebuilding and LOTS more.
 


I have a page that has some motorcycle (yes, some K bike stuff too) and personal stuff for sale (or TRADE!):    click here


Sidecar specific section (starting with my present rig, the tech stuff follows this):
 

This was previously Al Olme's rig.  I had it shipped to me in So. Lake Tahoe from Minnesota, by HaulBikes; whose service is very good (highly recommended by me, and many others).  I removed the Police-type saddle, and Authorities radio trunk prior to our 2008 trip across the USA,  installing the stock seat and trunk.   The Police/Authorities items have been sold.  I  have City-cases, as well as the Tour-bags and use whichever is appropriate:  I often use the rig with the Tour-bag on left, City-case on right, makes for easier access; unless on a very long tour where I need every cubic inch of space.  Specifications below are as I have modified the rig for my own purposes; and are in brief, as there is lots more I have done.

 The SKUNK flag stands for Sidecars Up Nort Klub; Up Nort stands for anyplace Up North of someplace.   



Tug wheels:  4.5 x 14" EZS. Tug tires: 175/70-R14 rear, 165/70-R14 front (will be 175 in near future)
Sidecar wheel:  300mm x 15" EML with 135R15 tire.  Sidecar wheel lead 13-1/4".
Front fork:  EZS Leading Link with floating brake discs, Koni 7610-1282 shocks (slightly modified by me); Brembo twin spot calipers from K bike. 
Entire ABS system was removed.
 Rear brake is Brembo two-piston 38 mm P108 & rear master cylinder is 16 mm Magura. 
 Brembo F05 sidecar disc brake plumbed to the rear braking system.
   Front wheel offset to right by 1-3/8".
 Toe-in 5/8" to 11/16" unloaded.  With driver and usual saddlebag  load, toe-in is 1/4"; with passenger in sidecar, 3/8". 
 The need for a steering dampener, which it has, is quite minimal, if at all. 
R1100S hand-guards.  Rugs in chair and chair trunk.  Multiple types of electrical outlets.  GPS.
The top, likely way over-designed and way over-built, was designed and made right here...sheesh what a job!  See #9 below.
