some are related to the BMW R1100S

This first write-up is very juicy. A few years ago, a guy named Roger
thread with a lie. He said I was suing the Pelican Parts BMW motorcycle
bulletin board. Hey, just what can
you sue a board about? This led to a feeding-frenzy of hate postings
aimed at me
and very nearly got the board deep-sixed by the owner of the website.
The owner forced Roger to post an apology. Since Roger happens to be
Moderator and Chief Bully of that bulletin board, he trashed
all my posts so nobody ever heard the truth. What a friggin'
snake!!! Here's my side
of the story — you won't read it on Roger's board.
Read the wild story and judge for yourself.
Some more or less general
Many debates about air/fuel
ratio, closed-loop operation, and related ECU mods. Here
is my experience riding around on an R1100S with an A/F meter. Lots of people talk
about A/F, but nobody has published on-road results (inertial dyno A/F curves are close to worthless). This report will
tell more than you want to know about the Bosch/BMW Motronic 2.4 ECU.
kinds of tools for "synching" (AKA balancing) carbs and
throttle bodies are being sold. Buying two (or three) ordinary, cheap,
automotive vacuum gauges
and then watching the balance at idle and while on the road "under load" makes the most
After-market mufflers and
how to re-pack them with products that work.
Clean your fuel injectors.
The cleaners will also provide you with before and after test results.
Don't ask me why, but you see voltmeters
on bikes and cars from time to time but never ammeters
reason has to do with money.... surprised?). But a temporary free
ammeter hook-up (using your voltmeter) tells you just about everything
you might reasonably want to
know about your battery and charging system. Read this and say to
yourself, "Why didn't I think of that."
is essential to prevent vibration and wobbling when parts rotate. Any
parts of your bike rotate more than, say, 1000 rpm? Right! So you
should do something about dynamic balancing.
Here's my take on bike suspensions, a primer.
Windscreens, bars, seats, pegs, and various things should be adjusted
on your bike for good ergonomics.
Sometimes easy to do but you need to know the theory or you could make
your aches worse.
Newer bikes use the angle method for torquing bolts. I think the old torque-wrench method
is better for curbside wrenches. Maybe?
of your stinking old internal combustion engine. Yeah, me too. Thinking
of a test ride on high-performance electric motorcycle like the Zero?
A long trip with my congenial wife from Toronto to Los Angeles through fabulous areas in the US west.
Some more or less
The recent BMWs have had a Paralever
rear suspenion. I'm sure this has been voted one of the greatest
mistakes of 20th century automotive engineering. Anyway, you can reduce
the stupidity of the design by installing bronze-bushing bearings to
replace the needle bearings. Do it today.
BMW have also been using multi-electrode spark plugs. There
are some reasons why that makes sense in a car, but not for bikes.
Here's a much better plug idea.
Here are some easy
THIS IS THE SMARTEST AND EASIEST
AND BIGGEST PAYOFF mod you can do: add a throttle counterforce spring.
For compelling reasons, it is good to add balance to a multi-cylinder
engine, particularly a balanced boxer. Adding some kind of balance pipe between
the intake throats makes sense.
Part of good touring ergonomics is a good windscreen. Here's a
little text about making windscreens.
to the R1100S bike:
Who are the kinds of people who own R1100Ss now? Are the types of people who are owners of R1100S bikes shifting? How does that affect the internet forum?
Would you like to see numeric results for actual, real-life, legitimate, sensible tests of paper, gauze, and sticky-foam air filter media?
in an effort to goose-up the HP at mega-herz rpm (pretty dumb place to
make your HP unless you do nothing but race), they installed an internal baffle to block 85% of the
front exhaust cross-over pipe flow. The cross-over is mostly just for
decoration! Remove your pipes and drill out the small hole in that cross-over baffle and
you'll unleash lots of power below 3500 rpm.
There was a guy selling stronger-looking triple-clamps for the
R1100S. I was so annoyed at the baloney and ballyhoo (not to mention
major peculiarities related to money) that I wrote this. I'm still
steaming too much about the FRK and its merchants to write coherently;
but that's next.
Here are some plans
related to the R1100S Corbin seat:
R1100S has a cowl or cover for the passenger part of the seat. Here I
show how you can make a needed parcel
The Corbin has a dreadful passenger backrest. Here's the way a
professional ergonomist would do it right — with pictures.
