Mine is custom-made... horrendously expensive.

However, I went this route because I had (at the time) specific requirements: I wanted the cell to reside on my FJR1300's pillion seat, yet it had to also fit between the two "legs" of the Givi rack.

The only way that's going to happen... is with spendy custom work. :banghead:

However, itr was worth it in the end... 4.9-gallon aux cell, plus the stock 6.6 gallon, gives me 11.5 gallons total of onboard fuel, which is the maximum allowable under Iron Butt Association rules for competitive Endurance Riding.The cell for the FJR came out pretty sweet....


Here I am laying out the floor of the cell using cardboard mock-ups:

Finished cell before the tankbag was sewn for it. Note red lever that opens fuel valve to start the fuel flow by gravity:

Right side - vent line feeds through the inner fender and exits aft of rear tire. You can also see the very important anti-static ground wire (wrapped around top of vent line) prior to connecting it to the frame of the bike.

Finished cell, viewed from the front of the bike:

The cavern created by the enclosure hold tools, tire repair kit and electric air pump to repair flats on the side of the road:

Linda Tanner custom tankbag for this aux cell installed, Givi topbox installed, bike was ready for some serious LD business:

And this cell now resides on my K8:

what are you looking for in a fuel cell?

Check out Jeg's and summitracing they have plenty of different fuel cells.

how expensive is expensive. Your set up is basically what i am shooting for. I need the bags as well. I want at least 5 gal of fuel.

IIRC, it was over $800 all total. And that was 4-5 years ago.

If you are looking for a 5-gallon rectangular cell without having to take out a second mortgage , another consideration would be Summit Racing. Here is a 5-gallon cell, with all fuel and vent fittings installed, and includes aviation-grade anti-slosh foam, and a flush-mounted aircraft-style filler cap, all for less than $86:

If you are put off by the polyethylene construction (which you shouldn't, as it is some tough, tough material), they also make a 5051 Aluminum alloy version that uses 0.10" think aluminum walls. This will set you back $139, but it features TIG-welded seams and mounting tabs:

The only slight drawback with these cells is that the filler cap is not placed in the optimum position unless your bike has a centerstand. For sidestand-only bikes, you really want the filler cap to be placed in the far right of the cell, vice the center.

Even then, you can't fill the cell completely unless you have someone hold the bike upright while you refuel. Example: the cell you see on my K8 holds 4.9 gallons, but because the bike is never level when I refuel (since it's on the sidestand), the most I have ever been able to fill it is 4.6 gallons. Had the filler cap been in the center as they are on the Summit cells, it would probably by closer to 4.3-4.5 gallons, thereabouts.
 
nice. No poly does not bother me at all. How much trouble is the install? What extras are needed?

Key to it all is a solid mounting job.

Underneath the K8 pillion seat is no less than six (6) hard mounting points. I used the forward two and the two rearmost to attach my rack "legs".

So... you'll need a sheet of fairly substantial aluminum (say, 0.125" or even 0.1875") that the Summit cell will attach to, and then go about creating your rack "legs".

When I was first experimenting with installing the FJR's feul cell on my K8, I already had the flat horizontal rack bolted to the cell, so I just used chintzy 'L' brackets from Home Depot. I have since replaced this Home Depot cheese with custom steel 'L' brackets and powder-coated them matte black.

Do ensure you route the exit of your vent line AWAY from the exhaust and AFT of the rear tire:

Then I tidied everything up with a custom Rick Mayer saddle, good for those 1500-miles/24-hr events:

All the above having been said, the single most critical aspect of an aux fuel cell project is installing the bulkhead fitting. You get one chance to do this right - one chance - and if you dork it away, you have a very expensive replacement on your hands. :disagree:
