Pro's and Con's to Airhead Aux fuel tanks?

Airhead Gurus!

Could someone enlighten me on the pro's and con's of the Auxiliary Fuel Tank system for an R90/6.

I need more range than my stock 16L (small) tank to be comfortable on the haul from CO to TN this summer. I've always fancied the look of the aux tanks.

What are the problems with them?
What are the bennefits to them?

Thanks

I dont know about those tanks specifically, but I will say its nice to have a little longer range, for sure. But introducing another system means that there is one (or two) more things to go wrong. I think they are kinda neat in a "huh..look at that" kind of way, but I vote for a larger tank.

Or...a couple of MSR bottles in the panniers. That's what I did in Mexico and the TAT this summer, and I only tapped into them once, and not for my bike.

Stopping at gas stations on a cross country motorcycle trip is one of the best ways to meet locals and get a flavor for the place. And as we all know, an sweet airhead (bike, that is) starts plenty of conversations around the gas pumps

pros - you can stop somewhere to take a break that isn't a gas station, you don't have to worry about gas stations closing when you're on back roads.

cons - uses luggage space, more weight to deal with, more complex system.

I think I'm gonna go for the Tank!

Yah,

I've been looking into the plumbing and vapor lock issues of the aux tanks. The ones I've been looking at are the paired small cans that mold into the side ofthe bike. It appears that there are some issues with heat and fuel flow (overflow) problems.

For the price I can probably pick up a touring tank or a police tank and accomplish a larger capacity and farther range.

I am NOT an airhead guru...but here's my 2c anyways

Here's what I put on my Harley to get some more range:

http://www.advrider.com/forums/attac...1&d=1226257174

It's a 2 gallon tank from tourtank.com

I put an on/off valve at the tank and Tee'd it in to my fuel line. I can run off the main tank, the aux tank or both. Like Elmoreman said--it will draw a lot of attention. People stopped me all the time and asked me if I had beer in it. Heck, I got pulled over by a cop for speeding one time and he asked me the same thing. "Why, yes officer, in fact it is beer. I run a hose over my shoulder so I can drink 100 degree Budweiser while I'm going down the road."

You shouldn't have any vapor lock issues--the system will work fine. The main problem is the ones that bmwblake mentioned. It takes up luggage space. I didn't have any issues with a 'more complicated system'. I got quick disconnects that seal when separated but never bothered to put them on. I think it weighs 4 or 5 pounds, so it adds a little weight but not a ton.

after some experience with an aux tank I'd say:

pros: cool factor, may be cheaper than a new tank

cons: loss of luggage space

I loved how folks would come up and ask me about it. The 2 gallon tank is $120 so maybe it'd save you some money. If money is not an issue a larger tank is certainly more practical.

I took a road trip from Alaska to Georgia with a 3.6 gallon tank. 16L is fine in the US. I'd get a 1 gallon Jerry Jug and strap it on some place. No sense buying more junk if you're not planning on taking long road trips on a regular basis. Heck, even if you are. Mega tanks aren't necessary. Hmm, so why do I have an 11.3 gallon HPN tank on my bike right now.....

Those aux tanks that go where the side covers go are a bit of a plumbing headache. They only hold about 1 liter each. It's a lot of pain for 20 miles of range. There should be plenty of 6.1 gallon OEM tanks available. Check all the usual used airhead parts suppliers.

What he said,
plus the fact that the Luftmeister sets are bringing BIG bucks, Like HUNDREDS of dollars. Screw that, the 6 gallon is the way to go. Just be very careful of rust-out. The area behind the knee pads is famous for developing rust issues due to the trapped moisture between the tank and pad. I've seen many an original beauty leak there. Hard to know unless you peel back the pads.
Good hunting.

Yeah...

Probably the first thing to do would be to get a /6 large tank and have it painted to match your bike. I've had and have both the large tank as well as the "Sport" tank and after running one for a decade or so, I know very well what a hassel the smaller tanks can be. Especially when your riding with other guys and have to stop all the time for fuel.

OTOH, with either tank you'll have to fill it up and stopping every hundred or hundred-fifty miles or so isnt the worst idea in the world.

Look around on IBMR or Ebay for a used tank or contact some of the used parts dealers. A shitty tank might cost you $150 but you can occasionally buy a NOS tank for $200 to $250. (Thats how much I paid for mine.) Just make sure that the bottoms solid and it isnt dented up. Around here, having the dents pulled out of an otherwise good tank costs as much as an undented tank costs!

PS: The Lufty saddle tanks currently bring $400 in mice/mint shape. Thats a lot of money to carry a little extra fuel but then again, how much would you pay for a gallon of gas if youre stuck at night, in 40 degree weather in the Adirondack Mtns, with no gas, during a rainstorm in October? Been there and woulda paid whatever you asked per gal! Loll!! If youre into Bling those tanks are BMW geek-magnets and they'll only go up in price. If you like the way they look (I do.) and dont mind the plumbing hassel, they might not be a bad investment.

Back from the dead...

In answer to a long ago question... or comment.
The single lufty tank was an option for G/S, GS and ST riders, if you wanted just one on the right side.

But in today's world a rotopax or even a marine style fuel tank would be what i would use to get more gas beyond a bigger tank.

I've seen and lusted after the monster G/S tank that was sold by Acerbies. Right up until the point I could finally afford to buy one. then it was taken off the market and the HPN version is just too spendy for my blood.

Nowadays my BMW's are short to med trip bikes so the massive fuel tanks and the range that came with them doesn't have the appeal it once did.

Coincidentally, I saw a pair of Lufty aux. tanks on Los Angeles Craigslist yesterday:

I have a set of these "unused " sitting on my shelf ... To me and extra 80km range is the difference to getting where I want to go and sitting at the side of the road .

Country service stations don't have the 24 hour card function that I loved riding around USA , and are famous of having " ish " opening and closing times 6am can be 6.45 on a Sunday morning and closing of 8pm can mean 7.30 on a Saturday night .

I can ride from my home in the country to the airport of 250 km's and only pass one station ... And if I am caught in traffic coming Into town that can mean getting off the freeway just to get that last 30 km's .

And you have to admit they look damn cool

Before going on a tour of Mexico back in '74, I bought a Rivets top case. Took the latches and hinges off, glassed in a fuel neck and glassed over the joint, put in a fuel valve and hooked that into the system. The top case held about five gallons. I used the top case for my regular tank and saved the stock tank for the reserve.

It would not last long today, the ethanol would eat the fibreglass!
