Well I thought the title may garner some interest.

But who is going to try this and provide an independent assessment. :?:

If this principle works it may also read across to the LAB.

Subject: Extra gas tank capacity

I have a AN K3 and I can fill my tank to the very top using a small diameter copper tube. I carry a 15 inch long one-eight inch copper
tube bent in a 3.5 inch U shape at the bottom, and a 3.5 inch L shape
at the top. From bottom of U to top of L is about 7 inches. When
refueling and needing an extra half gallon or so in the tank, I stick
it in the tank and hook the U under the collar of the tank and vent
the air traped at the top by the collar in the tank as I fill it.
You can fill the tank almost to the very top without the shaking and
filling to get the extra gas in. When full, you have to slide the
tube down to unhook the collar and withdraw it. Pour the little bit
of gas in the tube back into the tank and your done. Of course you
want to drive five or ten miles before parking it as filling the tank
this way leaves no room for fuel to expand if it get warmer than what
was pumped. The copper device fits nicely in the tank filling
compartment. I have had 252 miles on one tank with out running out.

You're still using petrol? Pah.

:hal

Yeah - that would be nice!

So whats the connection between Sergio Leone and that piccy?

Do you know? (I do not?)

 

[Bleeder]

I didn't know some had trouble filling the 400 to capacity. I do not. It'll overflow in a heart beat if I'm not careful.

252 miles on a tank had to be from the top of Mt. Everest to the bottom.



Peace.

Ooerrrr... I have no idea. A Fistful of Fusion? For a Few DeLoreans More?

Everytime I try and fill My Burgie up to the brim it overflows as I screw the cap back on

LOL!!!
Yes yes yes, we're not all not daft around here. Some of us know the connection between fusion and spaghetti westerns. Good God man it's obvious!! I've got that same set up and have to stop every 150 miles or so and pop the cap on the Flux Capacitor and drain the fuel.



Peace.

I read it a few times and I still don't get how it works.
Why not just carry a small gas can under the seat when
doing long trips. :lol:

There's a small space at the top of the tank that allows for fuel expansion. When you look down into the tank, you'll notice a tube that extended a couple of inches down. When filling the tank, the space around the outside of the tube is an air pocket. Using the device described, you allow an 'escape route' for that air and are then able to put additional fuel in the tank.

When I fill Burgman I rock him back on the centerstand as soon as the gas gets about half way up the filler neck as it lets out a burp of air. I continue to do this until it burps no more getting about two tenths of a gallon more in the tank. It also helps to park uphill during refueling if that is possible at your filling station. Just my experince and hope it works for you too. Anyone else do this?

[billmeek]

I use the bottom of the filler neck as my stopping point to attempt and fill the tank to the same level each time. It's made my MPG readings a bit more accurate. I also usually fill the tank on the way home. I need to leave the space for expansion.

increasing range....by cheating!

You could also take a gas can with enough fuel to fill your tank, put it in the freezer to make it 'shrink' and then fill your tank, as you ride the fuel warms up and expands giving you some additional range...probably be worth 20-40 miles anyway...I frequently have overflow problems if I fill my 150cc bike up and then go park it in a warm garage...whew! the fumes are terrible...but if you are leaving on a longish ride and want to test the range, chilling the fuel first should work like a charm.
