gas in the right side of the tank

The KLR FAQ has a section on gas that's left in the right side of the
tank even after you run dry on reserve. It says:
To get at this gas in an emergency, tilt the bike over to the left as
far as possible, and start riding again. You may be able to repeat
this process a few times.
Does anyone have first hand experience as to how much gas is actually
left there, how far can you get after every time you tilt the bike
over to the left, and how many times you can repeat the process?
Basically when I run out of reserve, do I have enough gas for say a
mile or two or more like 10-20 miles?
Thanks.

Hi Yan,
I used the 'double-secret-reserve' and found that it went ~8 miles
for me before it died, I did it again, and it went another 7 miles.
When I got to the gas station, it only took 4.8 gallons of fuel.
There is one caveat in all of this; I was using an inline filter at
the time and for whatever reason, the head-pressure of the fuel would
not overcome the resistance of the fuel filter. Same filter used by
Jeff Saline, a clear-plastic-made-for-MC made of splintered-stone
(sp?)filter bought at the same BMW Store in Sturgis. All that said,
the bike went to reserve before the design spec and the fuel was not
a true reserve. This has happened to others with a fuel filter
installed, while some get along with a fuel filter just fine. As for
me, I don't want to carry around 2 gallons of fuel that I cannot
access without removing the fuel filter.
Perhaps others might shed some light on the 'hydraulics' of why some
KLR's allow the use of a inline filter and others don't.
The only way to know what YOUR bike will do is to carry a gallon of
spare fuel, run it out of gas down to reserve, use up the reserve,
and do the double secret reserve. Not a recommended procedure on the
interstate, at least not going past the the initial reserve. If you
have to lay down the bike to get to the double-secret-reserve, you
will want to do it at a place that you are not going to get hit by a
cage.
To answer you question vaguely, In my distant memory, I believe most
have stated that they believed they had ~10+ miles of double-secret-
reserve.
AS always, YMMV.

More in the neighborhood of 4-5 miles.

I used this old technique on my old Honda XL600 and it was always good for another 6 miles. On the KLR, I did it once - and was underwhelmed. You have to lean the bike over to touch the left handlebar end to the ground, it bent the factory shift lever slightly, you risk battery acid spillage - and it only got me about 4 miles before the bike ran out again. A flashlight inspection proved that much fuel had moved back to the right lobe, and I wasn't riding aggressively enough to force fuel back across IMO.
The KLR's 30-50 mile reserve is good enough, (I went 51 before doing the tip-over) the extra 4 miles from the tip-over isn't worth it to me to pursue... unless of course, this means pushing it 4 miles.
FWIW

Interesting info Rev, I would have to say your fuel filter was a big player here in only taking 4.8 gallons with what we'd call an "empty" tank! I have a stock tank and, over and over each month, fill it with 5.3-5.5 gallons every time, never having to do the tip-over. (after the tip-over described in an e-mail a few minutes ago, it took 5.64).
I keep track of when the bike hits reserve on every tank, so when the fillup is done later, it's easy to run the math and estimate how much fuel must have been burned on the main tank. Running the math on the last 30 tanks of fuel show that I seem to have a little over 4.8 gallons of "MAIN" and just under 0.7 gallons of "primary" reserve... and that approximately 0.1 gallons of double-secret reserve, for a total of that 5.64 value quoted.
Agreed with the Rev that you just have to do the "spare fuel" run once with your bike and you'll know. We have seen varying numbers before when this question was asked on tank capacity, but 4.8 grand-total is way below the minimums I've heard before.
Rev, seems to me it's a simple "delta head" calculation of the pressure loss across the filter - not because of the flowrate mind you - but just a "surface-tension through the small openings of the mesh" kind of calculation. Maybe that filter has a head loss of 1" H20, meaning your fuel levels are all an inch higher when they stop being functional? I don't know why it works fine on Jeff's bike but we are dealing with tiny fuel pressures generated simply by gravity, so maybe the tiny variation in filter-to-filter becomes a big issue on non-fuel-pump bikes?

Any problems of this type that I had went away when I converted the vacuum
petcock to a manual one using Dr. Krok's kit. I have always used the
VisuFilter with the sintered bronze element and can run my IMS military tank
absolutely dry on the reserve setting. I think the vacuum petcock diaphragm weakens
over time and the fault is with it rather than the filter. JMHO.

Does the IMS tank have the ability to use the gas in the right lobe without
having to tip the bike over?

No...and it's embarrassing to have 7 gallon capacity and still run out.

I'm not touching that one with a ten foot pole ... or, more accurately, a 10.8 gallon tank. No sir.

hmmm. Ya know if you plan ahead you dont have to worry
about it, and as for bending a lever leaning it over,
maybe you should eat more wheaties?
