starting without the gas tank

I'm about to start my bike for the first time after a big project.
i would like to start without the gas tank to have more room to work on adjusting stuff etc
any ideas on how to do that?

Find a lawnmower gas tank and connect it to the carbs with a hose as a temporary tank. Plug off the vacuum line
 
Any container will work. I use an old fuel bottle for a camp stove, others use containers made of PVC pipe, or any metal can with a fuel tube soldered in place. Hang it at about the level of the gas tank when it's mounted. Too high and it will effect tuning.

You can also set the bike's gas tank off to the side on something the right height like a ladder or a big box, use a longer fuel line. I don't like that one because I'd probably knock the tank over. One more option is to run a line from the fuel tank on another motorcycle parked right next to it.
 
I don't use a tank, just a few feet of clear tubing. You'd be amazed how long a bike can run on just 1 or 2ft of hose. Just use duct tape to stick the top piece of hose to the handlebars or where ever.
 
I use a radiator overflow tank I purchased at a local auto store. Has a cap and everything. The one thing you do not want to do is to elevate the tank higher than the stock fuel tank. This can exert excess pressure on your needle and seats and possibly cause them to leak.
 
This high tech funnel system is my go to set up. :p

This was when I first got my 1100 E running after I rebuilt it.

I do love the sound of those Kerkers. I'm hoping to find a set for mine.
I had a set on a 72 Honda 750 and they sounded so sweet.

I don't think this is correct.
A pound of fuel is a pound no matter how high it is off the ground.

It is called head, the higher the tank the more pressure at the bottom. The same resins that water is stored in water tanks. It increases the pressure at the outlet.

Thank you for explaining.

No, to increase 'head' you would need to add more fuel, not put it higher, a pound of fuel is a pound of fuel, to increase 'head' you would put two pounds of fuel.

If that was true there would be no water towers.

Are you another who thinks that stuff gets heavier the higher you take it? Just to help you, the more you put up the heavier it gets. Again, a pound of fuel weighs a pound.

This is incorrect. The amount of liquid has no effect, zero. It is only the hieght difference that matters.

this is absolutely incorrect.

No, I'm one of those pesky people who has studied physics. :p

Think of it like this: Will a bowling ball falling on your foot from one inch hurt as much as one dropped from a building? Liquid works exactly the same.
 
Swim ten feet deep in a large lake, then swim ten feet deep in a small pool. The pressure you feel at ten feet is identical. The volume of water has nothing to do with it. Same thing as the pressure head question.
