Auxiliary Fuel tanks (Fuel Cells)

[ReSTored]

Here's some examples....

Those tanks are nicely integrated but awfully exposed vs. the OEM tank and some top box area mounted ones. I sure won't want to be rear ended at a traffic light with one installed.

I wouldn't want to be rear ended at all

I think the longest distance in North America between stations is 255 miles, so theoretically an ST can take on all of North America without extra fuel. You have to consider that with long-distance travel in remote areas where fuel supplies are sketchy that you don't get to use your full range. You have to increase your reserve margin if you are not sure where the next fuel is or whether the next station will have any

I've been caught once east of Algonquin Park in Ontario when I passed a station knowing I was going to be on reserve when I arrived at the next one. Turns out the gas station was closed because their supplier was late with their load of fuel. I had to turn around and go back to the other station and arrived on fumes with my refill being about 1/2 liter less than the tank capacity. Never again and when in the north or anywhere remote I refill when the tank is 1/2 - 2/3 empty.

I like the cylindrical type. If that's not enough, one could get a used 500lb propane tank, hoist it up there and plumb it as an aux gasoline tank. Handling might be a bit compromised.

A bit?!

I think I'd go with a tank in/on a trailer with a transfer pump.

How about a trailer that looks like a tanker?

Very nicely made. And all for only $7,000. Wonder how many gallons it holds?

That is pretty cool , but I think I would have an issue with the rolling resistance of 4 tires as opposed to 2. Also, Im not sure how it pulls behind a Spyder but im not sure id wanna push into a corner with a bike and the trailer trying to straighten me out because it has 4 wheels

I ran 502 miles with a Ron Majors tank one time on the Alaska Highway. I passed a gas station thinking no problem, 60 miles to the next gas station. Mid September, it was closed. Ran out of gas 40 miles after that.
Naturally I wanted to beat that record. 510 miles with a half gallon to spare riding around Lake Superior at slower speeds.
I sold the tank after that trip. I just get gas so it’s one less thing on my mind. It worked well but the bike was more simple and lighter without it.
There is a “point of no return” consideration that having more fuel can extend.
I bought a one gallon Rotopax for a potential ride up the James Bay Highway, 231 miles between stations. Don’t need but nice to have. It fits on the passenger seat, a duffel fits easily on it, it’s light, simple, cheap, a second one can stack nicely.

I bought a one gallon Rotopax

I did the same thing on my GS after I determined that I didn't need that much range any more... Lots easier to hoist a leg over than the aux. tank.

Ping me if your interested in buying, gravity fed all that is needed is a pipe run and 90deg angle plug into your tank. Tank/rack will need a
twisted throttle back rack for connection tho (Im keeping mine).

you are correct OBO, when I first got my ST 1300 it had a hondaline trunk. coming off of a Goldwing the ST 1300 trunk was more like a glove box so on went the aux fuel tank and cloths went in the wolfman. can't tell you how far it can go on a fill up ( both tanks ) but I have done a couple of 340 mile nonstop just to see if I could do it, I was thinking about doing a BBG at the time

 

[drbuzzard]

I also thought about a rotopax for one of my other bikes but using ( I already have one ) and mounting this would be cheaper and I can still gravity feed it https://www.ebay.com/itm/Genuine-Tecumseh-34156A-One-Gallon-Fuel-Tank-with-Cap-Gas-4-Quart-OEM/231812827293

What would be the best way to find a Ron Majors tank conversion for ST1100 ?

 

[beemerphile]

They are unicorns. Hen's teeth. The cheapest one that I have seen would have been to purchase an old tired Iron Butt bike for $1,500 that had one attached to it.

The Ron Major tank added 3.6 gallons to the 7.4 the ST 1100 had for at that time IBA11 gallon fuel total fuel allowed . After Ron died Jim Robertson bought the remaining ones from Ron's daughter . A filler cap was then added to the tank to spend up filling. To add the plumbing from main tank to aux tank was the hardest part of added the tank .

Didn’t an outfit called Sampson (IIRC) sell copies of Ron’s design for a few years?

 

[Larry Fine]

I'll just have to settle for stopping every five hours for gas. (Like I could ride that long without stopping!)

 

[beemerphile]

Sampson Sport Touring. Out of business now. I believe that the owner passed away. Maple Farkles may still be doing customs. They have a big FJR following.

Yes John. I do not believe they used the steel braided hoses like the others.
