GS auxiliary fuel tank

[Bokrijder]

Could someone point me in the direction of the preferred 1150GS auxiliary fuel tank setup? I find that my body/butt riding clock and standard GS fuel tank capacity are out of sync. If I could ride the stock tank to zero the relationship would be about right. Two or three gallons would be adequate. A jury rig system or loose containers are out. Optional larger bike fuel tanks do not appeal.

Thanks in advance,

If you don't want the trouble of all that plumbing and wiring, you could get a used Adventure tank (7.9 gallons) good for about 320miles feet up to feet down on the interstates. Perfect distance for that much needed gas fill and your other tank evacuation visits.

I just bought a used sacrificial plastic tank for off road use.
How am I going to convince my wife that the GS requires three fuel tanks?

WIMP! :D

The big picture guys. Keep things in perspective.

I just rationalized the need for and bought a used plastic tank and a final drive for off road usage.
And have now decided to leave home for a month to do the Peaks Tour.
No problems with all of this. Not a bad situation, I think.
An aux fuel cell is an easier sell than "I need another fuel tank."
The response will be, "I thought that you just bought one." -- "Well yes, but now I need a bigger one"
OTOH - If someone has an Adventure tank that they want to let go for the price of a cell system, I'm game

:idea Get one of those 'UNI' trailers convert it into a gas tank and catheterize yourself. :lol Get a 2-quart 'Camel-Back' for H2O intake and just let the hose run down your leg and out the bottom for output. :gerg Just think you could run 1000 miles before needing to stop for food :kbasa :stick

Plus you can strap more stuff to the top of the UNI-Trailer, of course you'll need to water (piss) proof it because at 80 everything is down wind... :eek

Motard, just remember one important fact, you can only go as far the weekest link in your travel group, no matter how much fuel 'YOU' can carry. :nod


Doc :D

You could get energy bars,protein shakes, and chew on some SF Candy and get 2000 mile days. :usa

Yeah but that would require a flip-face helmet ;)

The farthest I ever went on a bike was at or near 1150 miles and that sucked. I did 800 last summer (600 of it in the rain) it got dark and I hadn't hit anything more than 400,000 nats and flies before stopping for the night.

Sure it would have been nice to have the Adventure tank, and I didn't know how far gas stations would be up in Northwest BC, so I ended up stopping every 100 miles for a half tank and go. (I had a 2.5-gal jerrycan on the bike with fuel and never used it).

Aux cells are easy on Oilhead bikes. Get a Jaz 3 galllon Econo-Rail cell (or 4 gallon, your choice) and mount it either above the passenger seat or further back. You will need to fabricate a rack for the cell which attaches it securely.

You need a 3/8" 90 degree bulkhead fitting with a 5/16 or 3/8 hose barb, a fuel valve with two matching barbs, and a hose barb fitting to fit the outlet on the Jaz tank. All available (usually Wetherhead brand) at almost any good hydraulics and fluid line specialty shop.

For gravity feed you have the option of installing the bulkead fitting into the fuel pump plate - or can attach it with a 9/16" hole in a low point in the tank. On my R1150R I am directly into the tank. On Voni's R1100RS I am into the fuel pump plate.

If you want to add electrical complications you can use a 12v low pressure fuel pump and "T" into the fuel system return line. You avoid drilling a hole in the plate or tank - but add the electric pump, wiring, switch, etc. Your choice. There is enouch residual pressure in the return line that a gravity feed won't work reliably, but a decent 8 to 12 psi positive displacement fuel pump will. If you go with a pump get a decent one - not a little diaphram pump or it won't feed with any reliability.

I'm going to gravity feed and bulkhead into the access plate. You answered my question about utilizing the fuel return line.
My goal is not to maintain a ridiculously high daily mileage rate, but rather to efficiently complete a daily mileage budget.
I'd rather spend my break time lying in the grass at a rest stop or enjoying a view rather than standing at a gas pump.

Thanks,

Mully (over on Advrider) has a gynormous tank that I think he picked up from
Touratech. I think it might actually be bigger than an adventure tank.

"gynormous" really? wow :eek

[manicmechanic]

My R11GS has the 41 liter Touratech tank. That's almost 11 gallons.

There's a military term for that. It's called "Sierra Lima" :D
