Yep, I forgot a lot at first. I think they say it takes about 21 days
to unlearn and learn something new ;>) But it's not like it's going
to dump gas into your crankcase if you forget. I believe you have to
forget AND have a stuck needle in your carb.

Disabling the petcock does nothing but change the automatic feature of
shutting off your fuel to a manual situation. With the disabled petcock it
is still a gravity fed system. The diaphragm in the petcock is not a pump
but a valve to turn on the fuel flow when the engine is operating. There is
a spring that shuts off the valve in the petcock when there is no vacuum.

News to me. I've been running my IMS tank down to reserve and
refilling these last ten years. My tank never told me I was making in
unhappy.

Fred,
Isn't it true that disabling the petcock with Chris's kit eliminates
the vacuum aspect of fuel delivery? Correct me if I'm wrong, and I
probably am, but isn't it the vacuum that opens the valve
(diaphragm) to supply fuel? And if this valve/spring mechanism
failed to open or began to deteriorate wouldn't it begin to restrict
fuel to the carb? In fact, isn't it the diaphragms job to stop fuel
flow? And couldn't the level of fuel and/or pressure in the tank
have a negative effect on the vacuum operation of the petcock?
My KLR (2002) at roughly 40,000 miles started hitting reserve
earlier and earlier and I was still getting the same MPG. And,
reserve was totally unpredictable as to how far I could go before
the engine died from fuel starvation. Once in as little as one mile
with plently of gas in the tank! Now once again I could be wrong,
but I'm under the impression that disabling the petcock resolved
this problem.

I think we are talking about the same thing. The vacuum pulls on the
diaphragm which pulls a plunger with a seal on the end. The action of the
diaphragm is working against a spring. When you shut off the engine and the
vacuum goes away this allows the spring to push the plunger and seal to shut
off the flow of fuel. As I understand the way Chris's kit to work, the
diaphragm and plunger/seal are removed which allows fuel to the selector
valve at all times. Being a mechanic, I see lots of fuel leaking problems
and I think have an automatic fuel shut off is a good thing.
The diaphragm moves the plunger with the seal on the end to stop the fuel.
The "level of fuel and/or pressure in the tank" shouldn't have any effect on
the way the petcock works. There are a couple of tubes inside the tank on
top of the petcock that are used to make the "reserve tank". Maybe these
tubes have come loose in your tank is why your mileage to reserve has
varied.

Your suggestion made sense, so I double-checked my venting system
yesterday...
1) opened the tank cap, blew into the vent hose from the bottom - lots of
air comes through up at the tank
2) tried to blow into the metal nipple on the cap - very little/no air
seemed to go through
3) took apart the cap
Turns out there are two holes from the direction of the vent hose - a large
one that I think is from the vent hose itself, and a smaller one that I
guessing is directly from the atmosphere.
Air from the large hole passes through a stiff valve, then a soft valve, to
the tank.
Air from the small hole bypasses the stiff valve, goes through the soft
valve, to the tank.
Everything seemed clean, but when I tried blowing through the soft valve the
first time, it took quite a bit of pressure to get it to open. The valves
are little rubber flaps laying over some holes, and what was happening was
the very thin piece of rubber in the soft valve was sticking to the holes.
Once it broke free, it was easy enough to blow through. Blowing against the
valve made the flap stick again.
So I WD-40'd the soft valve flap to keep it from sticking.
Now I can blow into the metal nipple on the cap & some air does go
through.Not sure that this is a permanent solution (or that it was my
original problem) but we'll see.
I put a diagram of the cap vent valves in the files section (capvalves.jpg)
if anyone's interested.
thanks,
Dirk

Does a vacuum pull or does atmospheric pressure push?

Gary, I might be interested in trading cash for your black IMS tank if the price is fair. Sorry I don't have a white one to trade with. New ones are about $200 plus shipping so... how much would you let yours go for? My KLR is a 2000 model (A14).
Regards,
ian

Hello KLRistas,
I am thinking of getting the 6.6-gallon translucent tank from Dualstar;
http://www.dualstar.com/index2/Brand/Kawasaki/klr_650_military_fuel_tank.htm
i'm told that it does a pretty good job of protecting the radiator, as well as holds some extra gas that you can see. Do you know if there's any donwside to having one of these tanks (besides not being able to use a magnetic tank bag). Any info would be appreciated --Dan
