I'm dreaming a bit here... but I've got a couple questions... 1: Will the subframe on a cyclone have any problems holding a large duffel type bag on the rear seat, and a small 2 gallon gas tank on a Ventura rack? I think the combination of the two will weigh substantially less than an averaged size passenger. 2: Is the best way to install it something like this:  Would there be a problem with T-ing into the factory line between the petcock to the Carb? | ||

If you're going to soft mount the aux tank then I don't think you really want to plumb it into the system. Plus you have to remove your seat to check the engine oil. Look at what some of the IronButt folks do, many of them seem to mount their aux gas tanks on a rear rack behind the passenger area. | ||

Why not just carry two small (2 gal.) jerry jugs? If you made a rack that could hold one on each side, relatively low, that would minimize the negative impact of the added weight on handling and it would leave the seat available for a duffel bag. Plumbing an auxiliary tank to your fuel line may not be worth the effort and it will limit flexibility and oil tank access, etc. That way, a short stop to stretch your legs every 90 100 miles would give an opportunity to top up with 2 gal. Total fuel with two jugs would be 9 gallons, about enough for nearly 400 miles before you would need a fuel station. Good Luck, Dave | ||

Here's a link to an aux gas tank install on an X-frame Buell: http://www.badweatherbikers.com/buell/messages/142 838/252073.html#POST803539 Might give you some ideas  | ||

The tank would be perminantely hard mounted to the ventura rack, much like the Uly above. The ventura rack, on the other hand, is removable, and I would not run in most of the time (I run the grab handle whenever I'm not touring). The plumbing up to the valve would be perminantly mounted. But after the valve, to the tank would all come off with the rack. I thought that if I left the valve closed, and removed the tank, I'd have an effect like stopping the end of a straw with your finger, and nothing comes out the bottom. and therefor it wouldn't effect the rest of the system. Also, about the jerry jugs, the main reason I want this is to avoid stopping, not necessarily because I won't be near gas stations. Thanks for the link! But all the info I can find on this website is for XB's, so I'm very curious about plumbing on a carbed bike. | ||

The carb'd bike is gravity fed causing issues of it's own. I read here or on an IronButt site someplace about someone adding a fuel pump just for the aux tank and using that to just refill their main tank on the fly. Not sure if their line ran from the spare tank into the main tank or if it spliced into the petcock line somehow. Also not sure how a carb would like pressurized fuel if it isn't set up for that to begin with. | ||

My 2 cents? id use a rear tank that has a fuel shutoff, in case I wanted to remove at times, also a quick disconnect line at the aux tank...They can be had with a no leak check ball in them,,Then Y into the fuel line between main tank and carb...No pump is regiured for a carb...Water always runs down hill....A vented cap must be used on either tank.... Take alot at the dudes who run the Paris dakar...They got 2 tanks as saddlebags with spliter valves etc.....Just My Opinion...Hope it helps ya....Hb | ||

Do the math, gas weighs what a pound? Ventura rack supports how much? (not much) I have carried a metal 1 gal gas tank in my Tank Bag. Talk about a "reserve" tank... | ||
| Mikej |
Gas usually weighs a little over 6Lbs/gallon. | ||

OK, I'll ask. My S3 will go about 250 miles on a tank when cruising the interstate at 70 MPH and I assume your M2 would do about the same. You planning on competing in the Iron Butt Rally or something? | ||
| Nevrenuf |
can you find some kind of quick connect hose that you can tap into the fuell line and when your not using it, disconnect it at the line and at the tank leaving the line there but being able to take off the tank. doesn't noz have quick connects on them. | ||

anyone that gets 50mpg on a carbed m2 is either coasting downhill a lot, or is so bored that staying awake must be difficult.................. | ||

You'd almost be better off using a modified tank bag, and a spare fuel cap with a hole and hose. Shutoff valve in the bag, drop the hose into the main tank to the bottom, fluid tension will keep the bag from overfilling the tank (I think?), and you just have a bigger tank altogether. FWIW, water is 7 lbs per gallon. Little tidbit from my stage rigging days. 6 lbs sounds about right for fuel as it floats on water. | ||

Hey...Ya could do it the way we used too on the way to Sturgis, when money was the issue, rat bikes were ridden, and time was of no Essence.... 1- Magnum Wine bottle 1- 4ft lenght of garden hose Ya carried the hose around yer waist like a belt, had the bottle strapped to the b_tch bar, and ya made freguent stops at malls,bars,parkin lots to refill.... Worked great.... Ask Captain America and Billy LOl.......OnaHOG  | ||

I got 45mpg-55mpg averaging about 90mph across S.Dakota and Montana. 50mpg is a reasonable assumption on a functionally stock M2 on the street on the open road. YMMV.  | ||

I'll agree with the high mileage out of a tuber. My S2 typically nets high 30s/lo 40s around town, but slabbing it at a constant speed to Pocono last summer I got mid/hi 50s. Just goes to show if you can keep your hand out of it.... | ||

That's exactly what I was thinking, and tried to draw. anyone that gets 50mpg on a carbed m2 is either coasting downhill a lot, or is so bored that staying awake must be difficult. He is right! (with my bike at least) If I'm cruising at 55 mph (peak MPG), I'll hit reserve at 160 miles (46 mpg) and I'll run out by 220. Normal freeway or twisty's riding I'm on reserve around 130 miles (37 MPG) and then I'll be out by 185 miles. | ||

My M2 will pull 55mpg all day long running 70MPH -- you'll need a bathroom break before you'll need gas (if you're over 40 that is  .) G2 | ||

1- 4ft lenght of garden hose ...aka "Arkansas credit card"... ...ahhh, the memories! rt | ||

i apologize. i don't know anyone with a stock carbed m2. they don't seem to be too plentiful around here. no one seems to be able to keep their hands off of carb, intake, and exhaust. i have always wondered what a stock cyclone might be like. i know that fuel injected m2s get about 10mpg better. i do find riding a moto in a straight line for long periods of time to be an exercise in remaining awake.....................  | ||

off riding out of the radius of gas stations quite a bit. I put on side caribou cases (very durable and shock resistant) and carry a 2+ container of gas in one side and 2+ of water on the other side to "balance the bike out". If I cant get in and out on 2.2 extra gallons of gas, I swap out the water. If I need more gas than that, a small thermos will do in quickee emergency get me back modes. The Jerry cans give you a lot more flexibility with cargo and containers . | ||

oops, should have said fi tubers....guess there are ONLY carbed tubers....i need to study more ! | ||

geez, i meant ONLY carbed m2s...i need to go sleep....g'nite | ||

Centralization of mass is a basic Buell design criteria. So why not weld an aluminum bung onto the swingarm for a fuel line and use an electric fuel pump to transfer fuel from the swingarm to the regular tank as needed. Pretty "stealthy" and you could still use the other methods described above to extend cruising range further yet. Just a thought. Good Luck, Dave | ||

Buell mileage is all over the map depending upon your carb setup. I was getting under 40 on my S1 with a Yost tube no matter how I seemed to ride, but my S3 with a dynajet consistently gets 55 and up. |
