1) Assuming you're thinking of using it as a gravity system (my recommendation since parts can fail and gravity is pretty constant) What fitting will you use to tap into the existing fuel tank? This was the biggest committment on adding a gravity feed fuel cell to the FJR.
2) Bracketing. You have in your minds eye how and where you'd mount it?
The price seems reasonable for a DIY cell, but I don't get how you think you're going to double the capacity of your bike. The FJR is 6.6 gallons. These kits are 2 or 3.5 gallons respectively.
Well, it's for my Derbi, not my FJR. The Derbi comes from the factory with a whopping 1.9 gallon fuel cell! Yes on the gravity feed. As far as tapping in, I've got a plan there too. The little Derbi has a really unusual setup. The thing that looks like a fuel tank is actually a pretty damn spacious locking storage compartment. It'll hold my helmet, gloves, full rain gear, and more if you pack it carefully. The fuel cell is a plastic job that runs through the whole tail section and fills from under the rear seat. There happens to be a duct in the tail right near the high point of the tank. It looks like it would be pretty easy to install a quick disconnect tap into the side of the tank right inside that duct. Connecting the auxiliary tank would just require reaching into the duct and snapping on the other end of the quick disconnect on the end of a piece of fuel line coming off the tap on the auxiliary tank. Physical mounting of the aux tank is yet to be seen, but I'm pretty confident I can make it work.
Why all this trouble for a freakin' moped?? I'm glad you asked.
There's a charity ride in June to benefit pediatric burn victims. This year's event will be the third annual. It's called the Lake Erie Loop. It starts at a campground in Wellington, Ohio. One lap around Lake Erie, across Canada, back to Wellington in one day. You can take any route you like, but you must provide proof that you passed through Detroit and Buffalo en route (like a time stamped gas reciept). It's between 600 & 650 miles for the day. Sounds like a cake walk, eh?
Did I mention that all participants are piloting mopeds, scooters, and small displacement motorcycles 200cc or less?? Ok, 250cc for vintage class. B)
It's a timed event with a cash purse, and 50% of the take goes to the charity. There are classes for 50cc, 125cc, and 200cc with slightly higher limits for vintage machines 30 years old or more. Last year's overall winner did it in 11 hours 34 minutes on a 1980 Honda CB125S. The slowest guys took over 21 hours and there were 2 DNFs.
So, how's that 2 gallon fuel cell sounding now?? :haha:
You can get a better look at the little Derbish on my website at the link in my sig. At a scant 200 lbs fully fueled, it's a hoot to ride, and it has some pretty decent sportbike creds.
There is a "tourist class" for bikes that are too big for the competition categories. You can pay a fee and ride along, but there's no trophy or cash purse for the tourist class. All those entry fees go straight to the charity. Anybody interested can read more at
