If you own a BMW
airhead motorcycle, you
SHOULD join the Airheads Beemer Club:
CLICK
If you own a Classic K-bike (K75, K100, K1,
K1100), you should join the K-bmw LIST.
Snowbum
is also active on the K-BMW LIST:
http://autos.groups.yahoo.com/group/kbmw
Snowbum
is active on the SCT sidecar LIST:
http://autos.groups.yahoo.com/group/SCT/
There are two other websites/forums, if you have a K1200 or K1300
series BMW:
http://www.i-bmw.com/
http://www.k-bikes.com/
I discourage personal technical inquiries. I request that technical inquiries be sent to the
Airheads or other
appropriate LIST, so that questions and
answers benefit more than just you! This is because
of the large number
of personal
requests.
I'm not the only so-called 'Guru' on the Airheads
or K-bmw or Sidecar (SCT) LIST. You may
receive different or a BETTER answer; and I usually will
reply on that LIST.
IF you have posted to a LIST, and you have
not received the technical response you
need
after a day or two, THEN you MAY E-mail me directly, and I
may (or may not!) try to
help you. You REALLY
SHOULD have a GOOD reason to contact me, if you have NOT
posted to
the LIST!! Your query may well help others, SO,
PLEASE post technical
inquiries to the appropriate
LIST. I am likely
to ask if you have, or not!
If the message is "very
personal", you CAN E-mail to me at:
CLICK!
(you'd better have a really good personal reason!)
NOTE: There are many other sources
for information. The Airheads LIST is best for
immediate information
on Airheads,
but you can also e-mail Oak Okleshen
directly, at AskOak@aol.com.
Oak, a recognized major authority on
Airheads, will likely
respond
directly to you; he's not as crotchety about you not putting your
questions on the
Airheads LIST as I am.
The Airheads LIST is THE prime
source
for Airhead information, as is the Kbmw LIST for Classic K
bikes;
and the SCT LIST is for sidecars.
There are a
number of VERY qualified experts on the LISTS.
The LISTs
maintain ARCHIVES, which
you may find
useful. The Airheads LIST archives are at:
http://micapeak.com/archives/airheads/login.php
You will need your micapeak.com password to sign in.
That is not necessarily the same as your LIST or
airheads.org password.
You can subscribe to the AIRHEADS
LIST by using the following methods:
(note: 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. Please do not
send HTML or images to the LIST; 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. Send an e-mail to
airheads-request@micapeak.com
and put ONLY these two words in the message
area: SET
HELP You
need not
put anything in the subject area. You will be sent an e-mail with information to print out,
that explains the functions.
You will have
options to receive the LIST in various formats, ETC, so see
what you got from that HELP request.
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 more editing, in order to reply to a
message.
Put airheads@micapeak.com
into your computer address book, perhaps using a
nickname; Tech, or Airheads; so you
don't have to
type the full address when YOU post a 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)
Here is a lot 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.

Any use of the information contained in/on this website, is done solely at your own risk.
The not so lawyerly stuff:
The information on most of this website is 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, of printed or electronic copies. You are also granted approval for incorporation by reference or hyperlink, to my articles for most other uses. You must not abridge, modify, shorten, or otherwise edit my articles, unless it is made clear in them that that you are doing so, and you then prominently note that any change in INTENT, or INFORMATION, is YOUR responsibility, NOT mine! You are NOT granted permission to DUPLICATE my articles, in part, or entirety, 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 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. I am usually quite easy-going, provided you have no commercial interest in mind. 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 has Google Ad-Sense advertisements (or similar) at the top of the page (or, elsewhere's), 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!
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 takes you to the existing current
page. NOT ALWAYS! It is
best to go
directly to this website. I suggest you bookmark
(Favorites) the INDEX, and
not
the
page you are looking at right now. The index page is often called a HOMEPAGE,
and it is:
http://bmwmotorcycletech.info
The homepage has a DATE of revisions, so you will know if any
revisions have
been done to the
Technical Index page and articles, without a laborious
scanning.
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.
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 other things NOT on, and
NOT accessible, from this Index of Technical Articles
page you are now looking at.
Errors or
omissions on this site should be reported to me, and are
welcomed. That includes helpful comments!
©
ALL Technical ARTICLES ARE Copyrighted!! (unless
specifically so denied). Reading and
use
beyond this point constitutes an implicit acceptance of my
terms and conditions!!!
Our
Airheads are getting old. None have been made for private purchase
since 1995. 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
not have the 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 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!
I
DO recommend certain shops, and individuals, upon request;
or, see my URL pages
78A and 78B, below.
Be cautious when ordering from companies,
foreign or domestic, that may not be selling genuine
or REALLY equivalent BMW
parts.
If you cannot easily find what you want in my website
(searching manually is best), then
click here: SEARCH
PLEASE look
at the list of articles below, before you use the SEARCH

Huge
amount of information for someone trying to understand how
ALL types of carburetors operate
(especially needle/slide types, but also vacuum types). Much of the information
originally (?) came from an obsolete
www.startwin/dellorto website, and I have shown it in this
article without
Copyright release because I do not know where to
obtain a
release. I claim NO copyright on this article,
much of whose content may be public property. There
is
SPECIFIC information here on settings of the Dell'Orto
for the Airheads, and a link to an article on converting
an
airhead to use the Dell'Orto
(only the R90S CAME with
these). Included here are hyperlinks to other
carburetor
articles,
of considerable value!
Didn't find what you wanted in the above FUEL SYSTEM articles area? Use the search engine: SEARCH
Gasoline's:
This is not
an article by me, but a link. If you are truly
curious, and technically minded, this link to
a long
article
describes octane, gasoline, leaded fuel, unleaded
fuel, additives. VASTLY more than you ever
probably
even thought about
knowing about gasoline.
There are some really interesting things here and there
in
this article...from which you could
also get
to the other parts/versions
by re-arranging the URL.

ELECTRICAL System in your Airhead motorcycle:
Regarding
electrical schematic diagrams:
The R80G/S is similar to the R65 and
R80ST.
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.
Models with
the R65, ST & G/S type of instrument pod will have those things
pretty much in common.
The /6 and
later with
the other type of pod will generally have those pods in common;
variances are noted in my website.
My files contain schematics of all sorts of accessory items including Authorities
models.
If you need
to contact me
for a specific diagram, 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.

K bike???....see CLASSIC K bike section 3/4 way down
(towards bottom) of this page, for MORE hyperlinks to

Ask away...but

classic K bikes (2 valve K75, 2 valve K100). This is
not an article

on, leading to another website. A VERY extensive
article
on how the entire
fuel system and ignition system
works....with a lot of troubleshooting included.
The article includes extensive
sketches, schematics,
diagrams, flow charts, etc.
I find little
wrong,
except maybe the tiny section near the very
bottom, on using
the 4 each
16 ohm resistors
(parallel'd), with a
series connected voltmeter; which SHOULD be a current
meter. In addition, a
voltmeter should be at the
other side of the resistors,
to ground. In the article some of the use of
current/voltage
terminology could be a bit misleading
to someone
with electrical
knowledge.....but,
these are very minor
nitpicks! Download and print in color!
This is a VERY good
article! :

12. This is a hyperlink to the above website
that has a huge amount of K bike information, photos,

Sidecar
specific section:
This was
previously Al Olme's rig. I purchased it from Al and
had it shipped to me in So. Lake Tahoe from
Minnesota, by HaulBikes; whose service is very good. The Police-type saddle, and Authorities radio
trunk
were removed prior to our 2008 trip across the USA.
I installed for that trip
the stock seat and trunk. The
Police/Authorities items have been sold. I
have Citycases, as well as the
Tourbags.
I often use the rig with the Tourbag on left, Citycase 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, there is lots more I have
done.
