     I just joined the list and wanted to send a shout out. I've just
acquired an A14 (love that army/olive green!) 2000, and I'm luvvin' it. I've
got so many questions and so much I want to learn; I think I've come to the
right place. Whoa nelly! But this list do get a lotta postins! How do you all

It is like this:  The dampening force is linear, and a reactive force, just
as friction, especially static friction is.  The dampening force (and static
friction force) can't exist without the applied force opposing it, or else
the dampening force would result in spontaneous motion of the fluid.  As the
force applied increases, so does the reactive dampening force.  As with
static friction, as a force is applied to say your desk, you increase the
force, the static friction force increases in proportion and exactly
opposite to your applied force, until you reach the threshold, and the desk
starts to move and slide, at which time the force becomes kinetic friction,
which also increases in proportion to the applied force and the increased
velocity of the sliding desk but at a different rate as the static force.
The viscosity of the oil can be thought of as internal friction within that
fluid.  It would be easier to slide start your desk sliding across an ice
rink than across a concrete floor.

Subject: (klr650) re: breach/overheat/fracture mechanics

Someone described a "breach" recently...

I work in nuclear.  Having said that, I have little metallurgical
background, and I have even less training in fracture mechanics.

However, given the nature of the business, we chase even the most minute
leaks.  In CANDUs, (the D in CANDU is for Duterium, or D20, or heavy water),
the heavy water changes to Tritium when irradiated, and miniscule levels of
D20 or Tritium are measurable and are used to trace a leak.  Since D20 is
worth $hundreds/gal, they don't like to leak very much at all.  (Aside - D20
is naturally present and is not radioactive.)

Having said all that, the nature of certain leaks are that they are only
measurable at TRACE levels during a transient.  A transient would be a
change in condition, eg, pressure, temperature, etc... due to a change in
reactor power.  When the unit returns to steady state, the "leak"
disappears.  I know of one such leak that was elusive for nearly two years.

The change in temperature/pressure causes differential growth in materials
in the vessel.  This would be the same for a motor.  For instance, early
aluminum heads on cast iron engines had very bad reputations as our gasket
technology at the time could not compensate for the differential growth
rates of the two materials, and the gasket would fail.

Having said all that, I doubt that this is the case with our most recent
overheat problem, but I hope that it might bring some experience to our
"breach" hypothesis.

Eddie

Are they really small enough to flow past the oil filter, or is the oil
filter not a very good filter?  I could go with that 1000 mile interval,
except that my bike burns so much oil that I'd never make it to 1000 miles!

But hey, this also supports my argument that bike specific oils are a rip
off!

Ah, but the term Gross National Product is antiquated.  The current economic
term is Gross Domestic Product, which counts all final goods and services
that origionate here in the US, even if by a foreign company, such as Isuzu
vehicles produced in Indiana.  The bottom line is that Gross Domestic
Product results in US workers having jobs.  It isn't important which company
gets the profits, most likely it will be reinvested back into the US in one
way or another.

Its good and bad that US companies are setting up shop in Mexico.  Its bad
in that businesses that for years had operated here in the States and put
Americans to work showed no loyalty to the people that made their companies
what they are, and chose to move to where there is a cheap labor market to
maximize their profits.  If Ford produces cars that are finally assembled in
Mexico, then they contribute to Mexico's Gross Domestic Product.  The good
of this situation is that the workers in Mexico are hopefully going to be
able to improve their lives, get running water and electricity in some
cases, and hopefully, will one day be able to afford to buy goods and
services that still are made in the US.  This is free trade.  It is good for
the US to improve the quality of life in impoverished areas and countries,
it creates new markets, and every body gains.

> This is not politics, just common sense (the least common of senses).
>
You had mentioned to me that you were aggrivated over the debt that every
Mexican citizen owes to the US (monetary).  I remember that your economy was
suffering from rampent inflation and threatening to collapse, so it actually
benifitted us to lend the money, not to make interest, but to avoid a
catastrophy that would cost more in the long run, since our economies are
tied.  I do wonder though, how much of that money the US lent has actually
trickled down to the Mexican people?  But hey, have you noticed how much the
US government owes  to itself?  Our national debt is staggaring!

> Another thing, what is an acceptable compression ratio on a KLR?

Ah yes!  Motorcycles!  I'm not sure about the compression, let me
check.....My manual says that the compression range is from 77 to 124 psi,
or 530 to 855 kPa, or 5.4 to 8.7 kg/cm^2.  This seems like a very large
range, but you have to consider the operation of the Kawasaki Automatic
Compression Release mechanism which relieves cylinder compression for easier
starting.

Whoops!  Kinetic friction becomes roughly constant and independent of
relative motion, duh!

The analogy is still good though, if you ignore this mistake.

Why would you want to do that?  And what does this have to do with the
sphincter?

Hey Steve,

Messages here come in basically two different forms...  KLR based messages,
and non-klr related messages for those discussions that have nothing to do
with KLR's, or those that once did have, but have wandered off and developed
personalities of their own.  This list encourages both.

One way to manage the posts is to have all the non-KLR messages go to a
different folder than the KLR messages.  Non-KLR messages will have (NKLR)
in the subject line, and you can set your e-mail to mamage this.

Welcome aboard and enjoy the ride.

Cheers,

Arne

Hello yourself! It's always nice to hear from like-minded people.I enjoy
these postings very much! The bike is great! Goes anywhere,anytime. Not to
mention the roads aroound here are really crappy.I traded in a Voyager for
this bike,it's really great to be able to do more on a bike that just ride on
Interstates.I still think the clincher for me was the price!!!! $500 less
than both the suzuki and the Honda.thousands less than the euros.....

I was thinking this might have been a typo, but I never seen a new 2000 KLR
either.  The Dunlop 750s are only marginally better than a Trailmax in the
dirt.  There are much better tires than either of these out there for
playing in the dirt.  Depending on how much dirt or street riding you do,
you could go with the Avon Gripsters or all the way to a Pirelli MT21/
Dunlop K139.

The jet kits are made by Dynojet.  I sell them for $63.
