overheating?

I was just looking at the nice big KRL650 wiring diagram (Professor
Jims) and noticed that the temperature sensor to
the gage is separate from the sensor switch that turns on the fan. So
in the post that someone noticed the fan was
NOT running when the gage was way over the middle makes some sense.
They are independent of each other.
Just a thought when troubleshooting the problem.
Has anyone tried printing out the wiring diagram BIG? I have a color
printer that goes
to 24" X 36". I wonder what it would cost to get a big print laminated?

Around here it'd be a couple of bucks -- most places that laminate only have one machine, and it'll laminate up to either 24" wide or 30" wide.

Hey all! I had the pleasure of doing the IBA's Canada to Mexico
Border to border ride this late summer on Flame. The digest version
(so I can get to the ?)is this: We began at West Poplar, SK and rode
to Auora, CO in 13.5 hrs. Absolutly no problems at all! I love that
KLR! Slept for 4 hrs and off we went again...Stopped for fuel in
Pinon, CO and noticed an oil leak somewhere...I figure it wasn't bad
enough to get worried yet(risky, yes!) We stopped again in Springer,
NM. and noticed it had gotten a little worse but not pouring out
yet. I pinpointed it coming out of the left side of the case from
the bolt that holds the little rubber coated wrap that holds those
little wires. Hmmm, no tool kit with an 8mm...dumb!!! At a quick-
lube got a nut-driver and sure enough that was the one and only
leaker...cool! Only prob so far, if you can call it a problem. About
35 miles North of Las Cruces, NM the KLR began hiccuping. Not really
bad at first but the closer we got to Las Cruces the worse it got.
She was surging pretty bad when we pulled into Las Cruces for some
gas and a 20min rest. We were completing a 135 mile leg from
Sorroco, NM. It had gotten considerably warmer as we traveled
further south. We left Denver that morning it was 58. Now it was 90+
and the air was like a blast furnace. I'm not sure what happened.
She wasn't overheating by the guage and the fan started running only
after we stopped at the stop sign at the off ramp. Pulled up to
fuel, did so, drank a litre of water and we were off again after 20
min. She started just fine and ran great 60 miles into Mexico
and back to El Paso. In fact the little bugger ran great all the way
until we were South of Billings, MT about 50 miles. It was around
85deg. Then the surging began again, except this time she threatened
to quit while going down the road. When we pulled into the
Flying "J" she was barly running. I was kinda freaking out a little
acct I didn't think she'd pull out of it. Fuel and a litre of water,
about 10 or 15 min and I decided to pour some water out of a hose
over the radiator and into the fins. Seemed to cool off some. We
headed for home...she started and ran flawlessly the last 300 miles.
Sorry for the half story(Half???). But what gives? I've been part of
this group for a while and don't remember the KLR being an
overheater. Was the fuel somehow vaporising? I did have a pair of
Aerostich tank panniers on, could that be part of it? Any help would
be great. Any other IBA members ride their KLR's long in the heat?
Thanks. I rode yesterday both Flame and Oskar('04 Suzuki Hayabusa)
for a total of around 126 miles...today it snowed 4"...crap!!!

Well, if you can rule out loss of oil and the associated problems,
we can start on the fuel and the cooling system:
Just because the coolant tank is full, doesn't mean there is coolant
in the radiator. The cross over hose has been known to plug and the
overflow tank nipple has been know to melt shut.
Now for the questions:
Is the waterpump doing it's thing, is the radiator full, is there a
hose kinked, is the thermostat working/plugged. Lots of things to
look for.
The hic-upping would tell me fuel problem, but.
In my experience..... running overly lean (blocked or partially
blocked jet) will make it heat up, even running WFO into a partially
arctic headwind. I'd say check the coolant levels on both sides,
start the bike and see if there's coolant moving in the radiator,
drain the carb and look for sediment. If it persists, pull the carb
and do some serious cleaning, but most likely you partially plugged
the main jet for a while. Keep an eye out, and ride.

Oh, and NEVER pour water over a hot radiator if you can help it.
Don't ask...... When the plastic (no, not the KLR) cracks, it
really flies far
and sticks in things.

I'm going to guess that it's your jetting. Where do you and the bike
normally reside? Is it up in elevation? Is the bike and it's carb
settings stock? Did you notice you MPG going up while you were in
lower elevations?
A bike will run leaner once when the motor is warmed up, compared to
when you start it cold. It runs leaner yet when you go DOWN in
elevation. It will run leaner yet as the temp goes up, and as the
air gets drier. As this happens this WILL effect temp, but only if
your really lean. When it's too lean, the bikes will act up, but it
will still run. Then it normalizes as the conditions change back the
other way, either the temp, humidity, elevation, or any combination
of the above.
Did you start off with the bike in stock form and at a higher
elevation? I've noticed that if you have the KLR dialed right on the
edge of too lean (like they come stock), you can notice the things
that you mentioned quite easily.
You do NOT want to dial in a KLR's jetting spot on for high elevation
and then go riding down to sea level. A quick adjustment on your
fuel/air mix screw will fix this if it is in fact the culprit.

I beg your pardon Moose. That is exactly how my bike is jetted since I live
at high elevation. Over the years I have taken many weekend trips down to sea
level without any problems.

Ok, let me be more specific. If your bike was jetted using the "high
altitude" jets and/or settings, and you are quite a ways up in
altitude (8000 ft or more?) OR if you have played with the jetting,
leaning it out to the upper end of the rich/lean scale so that you
can get the very best mpg while not giving any thought what so ever
for lower elevation riding, and/or the temp gauge needle is riding in
about the middle of the gauge during normal riding (like a lot of
KLR's) at high altitude with a bit of lean surging here and there,
then coming down in elevation could lean out the mix to the point
of "too lean".
I told you it was just a guess though.

Moose,
I'm jetted for about 5500-6000 feet. I live at 4700' and the majority of my
riding is done at 6000' or higher. Watching the temp gauge when I've dropped
into the Sacramento Valley it's never gone above the mid point and I haven't
noticed any surging. My plug shows good color, no blistering. As a reference,
this is with Dynajet jets/needle. The one thing I have noticed with the jetting
is that the bike runs better with fewer discs in my IDS exhaust.

just my 2cents guys , but through my experience with klr's , hicups
also happen when,
the jetting gets lean (
dirt stuck in carb or a broken air filter , a loose or broken pipe)
or an electrical problem. ( battery connected properly? if its kinda
loose, detonation happens instead of the plug sparking )
mechenical problem such as burnt valve(s).
an overheating engine will just die off. hickup hickup and die. thats
what heppens.

G'day all,
I have a 2004 A18 that I've owned since November 2005. I had the
6000 km service done when I bought it, and it now has 8000 km up.
The bike seems to me to be overheating. The temp gauge shows quite
low when I'm on the open road doing 80 km/h or more. When I ride at
60 km/h or so the gauge goes up to almost halfway, and when I'm
sitting at a standstill, say in traffic, the gauge rapidly goes way
up to the right.
I have topped up the coolant it had used approx 200 ml in the 2000
kms I have ridden on it. The engine oil is right in the middle of
the window.
Does this sound normal?
Also, I'm thinking of getting a Clymer Workshop manual, but it only
covers models to 2003. Would it be OK for a 2004 model? I'm assuming
there would not be many differences apart from the large tank.
Thanks in advance
Nige
