Go to uspalstics.com and search for "Express Service Multi Purpose Tanks".
Any back yard mechanic should be able to rig a simple strap on way to mount these tanks for extended trail rides that would enable you to remove them in minutes for a trials event.  They are dirt cheap compared to trails or enduro type tanks yet quite strong.  I have the 1.5 quart unit and I am ordering a 3 quart unit tomorrow. They range in size from 1/4 quart to 6 quarts.

Here is the link, I am sure I could figure a way to strap one of these on.  
Thanks for the post!  

Have you checked out this tank?  http://www.lewisport.../trick_bits.htm  
Aux tank for your forks.

I have that tank on my 4RT at present but it does not add the range I need.  I have set the bike up with a seat for enduros.  I don't ride trials.

Great find!  I'll be putting one on my number plate for long rides.

Very nice. Thanks.

I now have the 3 quart size working on my 4RT.  I made a harness out of a used truck inner tube and had to modify the gas cap to accomodate an overflow tube like a regular motorcycle gas cap.  The gas trucks 40 miles out on the enduro courses will no longer be a challange for me to reach.  If anyone is interested I will post details of the porject with pictures.  This arrangement is so simple I can have it on or off the bike in two or three minutes, yet it is quite solidly mounted.

The Hebo tanks fit really well as they are shaped for the forks and rest on the lower fork tube clamps. However, their largest one is only 1.1 liter. I still find it easier and cheaper to carry the aluminum fuel bottles in my pack if I'm planning on a longer ride. It keeps the bike performance and handling consistent.

If I'm going for a long enough ride to worry about fuel, I'm going to be taking a backpack with me for tools, first aide and water anyway. And if I ride correctly, the bike will never notice the weight of the fuel in my pack. Plus, I always top off the tank at each rest spot and my pack gets lighter.

A gallon of regular gasoline weighs 6 pounds so a 1 liter tank plus fuel is about 2 pounds riding up there where weight is most noticeable. Put three liters up there along with the tank and you've got almost 6 pounds riding in a very sensitive area of the bike.

If you are just cruising on easy single track in top gear and are going for distance with very little Trials Related jumps or turns, then it makes sense to me. I've had fork mounted tanks before and had one that held 1 gallon, but it was not designed as well as the new tanks. It leaked and the mounting bolts that were imbedded in the tank failed. I bought another one and it failed too but that was way back in 1976.

I test rode the bike with the 3 qt. tank added today and I am quite satisfied with it.  I will try to post pictures before the week is out but I have been having trouble getting my pictures uploaded to the internet.

did anyone mention the godamn msr bottles from 8 thousand threads back?

i expected some sort of strap on joke out of you

FESTER said:

Yes, as a matter of fact, look at the post just above yours, it has the quote from my post above THAT where I talked about the "aluminum fuel bottles" Which is the Generic name for the Mountain Safety Research (MSR) fuel bottles...

What else was there to surf this weekend with TT down and all??

So Laser, would you dare to make a special edited version of a "strap-on tank" ??? wink wink, nudge nudge?? Maybe NOT for Prime Time viewing of course!

Please!! no descriptive details here, nothing to endanger a possible patent application...

Besides, if Preston Petty can market a tank using body parts for a name, why can't we?

Remember THIS tank?


How's THAT for a Yamaha Solution to the Scorpa Long-Ride option???

Seat, Tank and even the semi-Ape Hanger bars to help eliminate that "bent-over" feeling.

When we came across these bikes during Hunting Season, it was all we could do to supress a laugh long enough to sneak a photo before the owners turned hostile and trned their rifles in our direction.

I have the strap on tank working well now so I am entering my 4RT in the Cowbell ISDE at Walker Valley in the State of Washington on the 25th. With five quarts feeding directly to the injector I have about a 60 mile range before refueling.

Fester told me that he really likes the idea of a strap on front tank.
