Gas can as tank?

    I need to make some 200+ mile rides on my GEBE-equipped bike. Stopping every 30 miles or so to fill the little tank is not my idea of fun, especially since I don't want to have to look for gas stations. I've looked around for small gas tanks on eBay, but none of them are narrow enough to fit in the middle of the bike frame. I got an idea that maybe I can mount a pannier on the left side of the rear wheel and put a 2.5 gallon gas can in it, then run new gas lines from the can. Would that work?

    It'd be even better if I could find a narrow gas can of that capacity, something like the old Jerry cans, but not 5 gallons.

    Also, does anyone else have a problem with the snap ring holding the bearing in the motor mount coming off and letting the bearing come out? I've put that thing back in about ten times now and seriously thinking about supergluing the ring in next time so I don't get stuck in the middle of nowhere with a loose bearing.

    I think the best way to find out is to try it. Try to have the gas tank up as high as possible to make the gas line aas short as possible

    I suppose if gravity is going to be a problem with the fuel supply, I can just carry the gas can filled with premix on the side without hooking it up. Won't have to worry about modding the fuel lines or anything that way. Refilling the regular tank every once in a while isn't so bad, I guess. At least I won't have to worry about looking for a gas station during the trips.

    Does the Zenoah engine really need 2000 miles to break in? I've only got about 1000 on mine, so I assume this means I should do a lot more short trips before running the Zenoah full throttle for ten hours at a time.

    At 1000 miles, your engine is broken in!!

    I dunno if you'd ever wanna run the engine WOT for 10 hrs at a time, however. For some reason, the 2-strokes I've ridden need you to vary the throttle from time to time. I usually ride WOT if I'm on a fairly busy road & NEVER when going down a hill. Those are the only throttle limitations I'm sticking to for now.

    I'm no GEBE guy & dunno what GEBE u have but it shouldn't really matter....all that i've ever seen have their fuel tank below their carby so that must mean either they have a pumping carby or a seperate pump to pump fuel to the carby.Whatever system u have an external fuel tank can be put anywhere(within reason)
    Call GEBE and find out which system they use and how it tap into it.
    Introduce yourself. :)
    Good luck man.

    I've heard of using a canteen.

    If I were you, just to make it easy I would strap a can of gas that is premixed to the side of your bike and fill up when you run empty.

    Okay dude I found a guy that has done exactly what you want to do. Check out the pic in the attachment.

    Hmmmm I say Hmmmmm. I'm wondering if you couldn't just use the gas tank from the crappytime that you've given up on for your 4 stroke rack mount. Just keep it strapped to the frame and run a line back to the engine. Hmmmmm

    Here's what I use for an extra tank. I bought a bike rack, removed the rack part, turned it upside down and attached a HT tank. I sealed the vent on the stock tank and let the HT tank do the venting.

    I can't find the pics now but Someone did exactly what you are asking and had no problems with draw from the tank to the gebe engine... I'll keep looking for the thread

    Saw Willie's great story on GEBE. He seems to be having lots of fun with the rig.

    Good work on the auxiliary tank set-up. Lots of people here interested in longer runs and fewer stops. Just might give it shot myself, but will likely tuck it in under seat with one of those tanks from down under.

    Where did Willie locate the "muffler?" Just curious. I already know, after two failures, that typical mufflers for these engines do not work unless they are built too big/long to be practical, at least for me. I like 'em small, tight and simple - ;}

    I've decided to go with my second idea (which Codi79 also suggested). I'll carry a two gallon CARB-rated gas can with premix on the left side of the rear wheel. That should give me enough range for the roughly 300 mile ride without needing a gas station en route. Stop every 30 miles or so and refill the tank on the engine. It'll give me the opportunity to stretch my legs a bit every hour and makes it easier to fill up for the return trip since I don't need to pull the bike up to the pump. Thanks for all the input.

    I would get a ~5-10 gallon marine tank, the type that is used in small motorboats. You could turn it sideways or just strap it to a rack. (or, for that matter, put it in a saddlebag or basket)

    5 gallons of gas weighs over 43 lbs, 10 gallons- over 86 lbs. Yikes!

    A can't imagine my....resolve....holding out for an over 500 mile trip that 5 gallons would represent. ;)
