2nd question - carb tuning probs

OK, now to the carb. My '01 came with an IDS2, the Stage II kit
installed (150 main, screw out 3 turns, needle 3rd position), and K&N
filter. I live at about 7000', and the altitude of my riding ranges
from about 4500'-11,000'.
After a few rides (fuel consumption just over 30 mpg!) it was clear
the bike was running too rich (I bought it from a guy in Las Vegas -
guessing altitude there maybe 1000'). I dropped to a 140 main and
turned the screw in to 2.5 turns. Still too rich. I dropped to a 136
main, needle in 2nd position - somewhat better, but here's the
kicker: I've yet to get over 33 mpg! (I bought this bike to do my 150-
mile round trip commute, to "save gas", but my Honda gets 40 mpg -
there goes my excuse to ride!) And the plug/exhaust still look like
it's running 'way rich.
Mix all this in with the electrical problem (see earlier post) and
I'm pretty confused.
1. I've read that trying to run the Stage II kit at altitude is a bad
idea - comments?
2. Anyone else with my same setup running at the altitudes I am -
what main jet/screw setting/airbox setup do you have?
3. What MPG should I be getting?
Anything else you think might be helpful! I'm kind of tearing my hair
out. I want to like the bike, but I sure don't trust it at this point.
Thanks in advance.

Clean your air filter lately ?
I never really checked mileage, but guess 40 for me, tankful last me a
long time, heck still got the Sta-Bil treated gas from last year in
mine.. I do not have far to go to get anywhere.

Dan,
Your poor mileage / jetting problems sound like a direct result of a weak
spark due to your low voltage from that dead battery. That's why your
engines starts to die off and stumble at higher cruise speeds, the spark
isn't strong enough to fire off the mixture from the larger throttle
openings. Get rid of that battery and check the voltage while running as
suggested and I think your problems will go away. 12.25 volts is virtually a
dead battery, I'm surprised it runs at all.
As a far as your jetting goes you'll have to start from scratch when you
get some spark to the plug. I'd start with what you have now and work my way
up on the jetting because it's easier to diagnose a lean condition than it
is a rich one. I think with your pipe and intake side and altitude you'll
need at least the 140 main and third from the top on the needle, pilot out
to suite your taste. Once your close on the pilot screw make fine
adjustments, not just half turns. I have a similar set up as your original
and mine runs fine at 11000 feet.
Good luck,
Dan Bittner

That would be true if the KLR had a points or TCI type ignition, but it
doesn't. It has a magneto-powered CDI system that works completely
independently of the battery and charging system.
The starter won't work without a good battery. but once the engine's
running the battery and "alternator" are not necessary for ignition.
If the bike is having symptoms of poor ignition I would guess it's a
fouled plug.

electrical gremlins and other strangness

SEE There! I told you I didn't think it was the wiring harness. Now what
would you like to spend that $160 on since I saved you the price of that
bundle of wires?

sure I have traced the source of my trouble to a badly corroded negative
battery cable. Seems when you drop the bike on it's left side in front of
the pretty girls selling t-shirts at Barnett Harley-Davidson out in El Paso,
you get the double whammy! Thanks again for all the help, you folks are
great!

Voila!! the color of the bike in the pics changed. Check this out, I had
downloaded the origninal fuschia/pink/effluent version. I just went and
grabbed the new version. If you view them side by side, you see it's the
same picture. I think they just turned down the exposure to get a more
acurate representation of the bike. Pay attention to the grass and gravel
road in the background. The pink image is just too hot (bright). Now, maybe
those of you who were thinking DR for next year can come back home!!!
