[TD="colspan: 2"]I have used this header tank for years and it is as cheap as you can get. This set up was given to me by another member of this forum. I am not the genious who came up with this. Wish I could take credit.

Parts needed:
1-lamp post (sourced from garbage)
1-law mower gas tank
1-6 inch piece of angle iron (mine came from left over from garage door opener install)
1-Briggs and Straton Fuel shut off valve (from lawn mower)
4 feet fuel line (mine came from snowmobile)
1-inline fuel filter

Total cost under $10

Most old lamp posts have a threaded rod at the top to attach the lamp shade and they usually still have the nut still on the top. Pull the wire out of the lamp post throw it away. Take the 6 inch piece of angle iron and using the nut secure it to the top of the lamp post. Take the law mower fuel tank and suing ip ties secure it to the angle iron. Attach about 1 foot of fuel line to the nipple on the tank. Put fuel shut off valve at end of fuel line comming from the tank and attach the rest of the fuel line to the valve. I put the fuel filter at the end of the fuel line so I can attach it to the fuel line comming from thecarb. Fill tank and attach it to fuel line from the carb. Turn on shut off valve and run your bike. The lap post has a nice large weighted base so it wont tip over easily and it will be 2 to 3 feet higher than your bike. Enjoy[/TD]

Well done, Macguyver.
Added bonus....no more cutting the grass.

Seems too difficult, I just hang mine on the handlebar of the next bike over.

 

[dorkburger]

How do you ride like that?
I did similarly with an old weedwhacker tank that I hung from beam in the garage.

 

[Who Dat?]

You definitely have the advantage of (lack of) price there, but I have one of THESE that I hang on the handlebar.

Fewer parts to keep track of and much easier to transport if I need to work on a bike somewhere else.
Also does not rely on "the next bike over", which a luxury not found everywhere.

Whatever your method, don't raise it any higher than the stock fuel tank, it might force gas past float valves that are just barely able to hold the pressure of a stock tank.

Holy Cow, $52 for a plastic bottle?

+1 on hanging it too high having an effect on the fuel level, but you may have restarted an ongoing argument among those members who don't know how fluid pressure works.

I just set the motorcycle's fuel tank on a step ladder next to the bike and use a 3' length of fuel line to connect it.

Stick a golf tee in the vacuum line, put the petcock on "prime", and off you go.......

I too have the $52.00 plastic bottle (although I think I paid $40 on ebay) that is very useful and easy to store.

Now on to the petcock height issue, which I did not know. The last time I used mine, I hung it high on a garage door track. For two days after I used it, I smelled fuel near the subject bike!! Could it be because of the height? I never did pinpoint where the smell was coming from and I believe I have checked the oil level since.

I would be afraid I'd knock the beautiful gas tank down and dent the heck out of it..... I do have a few L tanks laying around here I could do this with.

L tanks. Ha! I'd be afraid one would wussify my bike.

I use a rubber bungee strap to keep them secure. Been doing this for ten years, haven't lost one yet.

 

[tkent02]

I think an L tank is OK for temporary use if it's beat to crap and rusty. A shiny new gay one, no way.

This is not true.

Here we go.

This subject started a very entertaining thread a few years back. If this one goes the same way, I'll sit back and watch before weighing in.

I ended the last one, probably too early for all the fun it was.

Er..I don't think so...

Er..I don't think so...

Perhaps we're talking about two different ones then. I used the math stuff and that pretty much ended it. Looking at your join date, we evidently are. The thread I was referencing was probably back in '07 or so.

It was almost as good as the torque wrench thread.

Always good fun to have a look at that experiment.

To be fair it was a long time ago and I've forgotten most about it, I do remember being alone and up against some very adamant people and got a bit mixed up myself but anyway it was fun.

Oh boy. No way man. My luck is not close to good enough.
