technical inquiries to the appropriate LIST, below.
If the message is
personal you can contact me at: CLICK! BUT.... I may tell you to "take it to the LIST!
That way, answers benefit more than just you! Taking your query 'to the list' GREATLY reduces my E-mail hours.
PLEASE use the LISTs!! You CAN get advice from me, Snowbum, and many others, on various LISTS.
"Airhead" is slang for a BMW boxer air-cooled twin manufactured between December 1969 and the
end of production in 1996. "Airhead" does not include the boxer twins known as Oilheads, nor
Hexheads nor Camheads.
Technical LIST for EML sidecars: http://groups.yahoo.com/neo/groups/EML_SCL/info
Snowbum IS active on this LIST, and is a Moderator. This list is primarily technically oriented. Typically rather quiet.
The SCL in that address stands for SideCarLounge, which is of no importance at all, it is just how the list was named.
Western USA branch of the United Sidecar Association: http://groups.yahoo.com/group/USCAWest/
(Snowbum monitors that list). This LIST is primarily for chit-chat, places, people, events, etc. It tends to be rather quiet.
You may also be interested in http://www.sidecar.com which has a LOT of sidecar technical information that is FREE.
If you own a Classic K-bike (K1, K75, K100, K1100), join the K-bmw mailing LIST.
Snowbum IS active on this LIST, which is primarily technically oriented:
There is an Internet-based FORUM for the K1200-K1300 series: http://www.k-bikes.com
Snowbum is not on that list.
There is a K11 owners group list. The site is quite active in the FORUMS section.

Our bikes are getting old; the oldest Airheads are now officially regarded as ANTIQUES. You can NOT rely
dealership for repair work,
nor for the proper
parts and parts numbers. Dealership personnel may
well NOT have the proper knowledge nor background.
DO strongly consider independent repair centers, especially ones that participate on LISTS & FORUMS.
I DO recommend certain shops, and individuals, upon request. Especially see my pages 78A and 78B, below.
BE CAUTIOUS ABOUT WHERE YOU GET WORK DONE, WHERE YOU PURCHASE PARTS, EVEN WHEN 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 (passed along) 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.

"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.

"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:

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+) but many schematics in it are very difficult to read, some are quite 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 to 1996 or so), 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. Because there are CONSIDERABLE similarities between various models, enough of these schematics are on this website to enable you to work on your bike.
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, as appropriate, FIRST. I may or MAY NOT see your query if you post to the BMWMOA forums. 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, DO 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 a lot of my time, and 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.
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; differences are few, and 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; which have only a few differences
such as lighting, whether 3 or 4 cylinders (ignition is primary schematic difference); and for the fuel
injection computer, whether Jetronic or Motronic. ABS? Then whether ABS1 or ABS2.
Here is a link to a German website,
that has a LOT of Airhead (and some R1100 oilhead and other)
NOTE: Some of the schematics on BMW's OWN CD of schematics, for early eighties bikes, are wrong in some areas.
Links for more electrical schematics, etc., are found in article #80, below.
|Some BMW schematics will show things NOT on YOUR bike, which were special equipment or added accessories.|

7. Link to German website, with LOTS of Airhead (and some R1100 oilhead)
electrical schematic diagrams. Click on the Shaltplan, shown in red on that

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!
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.
9. Hyperlink to a forum-type website. Mostly on Oilheads, but some Hexhead,

CLASSIC K-BIKES ARE K MODELS K1, K75, K100, K1100, K1200
NOTE: Snowbum does not work on, nor have hardly much knowledge, about certain bikes, these are the K1300S; K1300R; S1000R; HP4; K1200S; K1200R; S675RR; K1600GT; K1600GTL; and K1300GT. For those, you might be interested in the following website:
http://bmwsuperbikes.com/ that appears to be a duplicate of http://bmw-k.com/
Snowbum is active on the K-BMW LIST:
http://motobrick.com Forum style. Classic K bikes. Active, lots of opinions, watch for awhile to sort out who knows, who guesses, etc. Snowbum isn't on this forum.
http://ibmwr.org The so-called BIG LIST. Has a section on tech. Lots of K bike stuff. Snowbum participates some on the techlist.
http://k11og.org/ The mainpage is seldom changed, that is, hardly ever anything added to it.
BUT, the FORUMS are active.
K1100LT and K1100RS repair manual:
Classic K bikes model history, K1, K75, K100, K1100:
There are some things missing, and some that need embellishment, etc. There were changes in the
rod lengths and pistons, the radiator got more fins, lots of little things also. But, Anton's list is a good one.

Highly recommended by several people.
Here is a place in the Netherlands that does all sorts of modules/computer brains, etc.:
Re-manufacturing; 300 Myles Standish Blvd.; Tauntonk MA
(866) 573-2740; (508)-822-4490 http://www.bba-reman.com
I have TWO reports that do NOT recommend these folks, and none
that DO recommend.
14B. 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 also good advice
for the ABS main computer plug connections. Here are a couple of
articles to look at:
http://ibmwr.org/ktech.shtml Scan down for the ABS articles
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:
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! Info is well down the 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
of this in some depth.
20. See Airhead section article #30 regarding the ignition circuitry, lots of useful
information on the Hall element, etc. The following article, while for a R1100RT
oilhead, is useful for K bike owners; it is illustrated & is about replacing the
Hall sensors for a R1100RT sensor repair, & is SIMILAR for a K bike:
21. Doing a rear main seal job is involved. Here is a video of the procedure to R/R
the 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.
In GERMAN for sound. 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. Information for Classic K bikes, NOT just the K100.
Many Service Bulletins here too:
23. A lot of K bike information. Has all the wiring diagrams for has a lot of
information. In German, but very useful! Covers all the Classic K bikes (K1,
K75, K100, K1100, K1200), & lots more. Wiring diagrams are under Shaltpläne.
24. How to replace an oil level sight
glass rev. 10/14/2012
25. Service Information Bulletin SI-2630R: failure to use all fuel in the fuel tank,
whining noise from the fuel pump. This is a link to a PDF file on this website.
The sketches are not very clear, so look at them with a critical eye!
If you can furnish a really nice clear copy of that bulletin, let me know.
26. Engine oil, & lubrication in GREAT DEPTH: see article 51-C, ABOVE
27. Worn rear drive splines? Bad U-joint? Upgrade?
see: http://www.brunos.us/Bevel drives.htm
Doing a K75 rear drive input spline and driveshaft and swing arm lubrication?
This is a link to a how-to video, it's in German, but you will understand it. Note
that normally one does not pull the swing arm, in this video I suspect it was done
to replace the boot, and check the swing arm bearings.
28. New style seal used on K bikes at the alternator drive:
29. Link to a 6 part video series on how to disassemble and reassemble a
Classic K-bike, to do an input spline service. Includes a lot of service
and commentary on things the servicer found on this bike along the way.
Lots of good hints. Very complete, including the swearing.
30. Control cables problems
31. Re-keying locks, especially fuel tank lock; problems with the cap; and other
also: see my article 75 in the Airhead section
32. FUEL CAP on K bikes (and other bikes too). This is a
video. It covers R/R cap
internals. No information on keying locks.
NOTE: The "kit" in the video, 16-11-9-062-461R was sourced from Bob's
BMW. The "R" means Bob's is selling a repair kit. Be sure to get gasket
see my article 75A also
Adding running lamp function to turn signals, etc.
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.
I have a page that has some motorcycle (yes, some K bike stuff too) and personal stuff for sale (or TRADE!): click here
previously Al Olme's sidecar rig. I had it shipped to me from
Minnesota by HaulBikes (also known as Daily Direct); whose service is very good (highly recommended by me, and many others, including dealers). I removed the Police-type saddle, and Authorities radio trunk prior to Penny and my 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 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 (when Penny is along!!). 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.
