starting without the gas tank

[eran_k]

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.

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.

I bought one of these: http://www.amazon.com/Motorcycle-Sho.../dp/B004NV42PQ

But many of the methods mentioned above will work just as well.

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.

So did I , with all the tools you need to work on a bike this one might be expensive but it still doesn't cost that much and it is real convenient.

Thank you for explaining.

I have the same one works great the shut off valve does not like ethanol in the gas tends to leak thru the handle. Non ethanol gas does not. Guess the alcohol thins the gas. I use mine all the time works great just a pain to fill not enough hands to hold it and pour

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.
