I am not convinced that stripping ethanol fuel out of E10 is really that easy.  There are other additives in the gasoline that could be stripped out with the ethanol, and the gasoline will retain a small amount of the water in solution....and it is possible that the absorbed water could be as damaging as the ethanol.  I think it would be far better just to use an ethanol treatment in the fuel.....the E10 doesn't cause any harm as long as you don't let the fuel sit in the tank for extended periods without a preservative (Stihl recommends draining the tank if the equipment will not be used for 2 months).

Here is a site that provides information on where you can get ethanol free fuel.  The number of Marinas that carry ethanol free fuel has increased substantially......however this fuel most likely won't be carrying and road tax - so you will have to buy it in a can and then transfer it over to your bike when no one is watching.

I run my bike all year on the E10 pump gas....and the vacuum petcock is the only part of our fuel system that seems to be sensitive to the ethanol.  I turn the Raptor petcock off when I am 1/2 mile from home, and the engine is dying as I pull into my driveway....this keeps as little fuel in the float bowl as possible.  When winter comes I drain all the E10 out of my tank, and I then put in a small amount of Avgas 100LL just to flush the system out, and I go for a short ride....then I drain out the Avgas and put the bike away for the winter.  (Avgas has no ethanol and it evaporates without leaving any varnish behind....but it does have lead so don't use it in any engine with a catalytic converter).

Here is how you can test your fuel to see if there is any ethanol in it.....and it basically is done the same way you are proposing to use to strip the ethanol out.  The water does work to do this - I just don't know about the quality of the gasoline that is left behind.

I heard you can burn the water off with propane torch  

Thankfully we have a couple of non-ethanol stations I have access to. I don't use them every time, but do try to use them if and when I can.

I heard that if you slowly bring the gasoline to a boil, in something like a fish fryer, that the ethanol evaporates off first, so as soon as it is at a full boil you have pure gasoline.  

JUST KIDDING! Don't try this you silly folks.

Jeeeez, just when "Turkey Fryer Home Fires" are about to start popping up on the evening news....

SCAREY STUFF, here...

Sta-bil and all is well, stock petcock 97.

In my area you can buy ethanol free gas but only in 91 octane ,at about$.50 cents more a gallon .If I ride 3000 miles a year I've spent $60 extra on fuel for a bike that runs just as well on 87 octane.SO....save your money,buy a raptor an run the cheap stuff worry free.

All this talk of "removing" ethanol from gas has my old fart safety side concerned. I do not wish to see you make an "ash" of yourself . Here's another cheaper example of pre-packaged fuel that may save effort and injury:

Apparently Husquvarna already addressed the issue and they are in agreement with your info: Ethanol is death to the 2-stroke engine, and additives apparently don't help much. They make their own version of fuel, somewhat more expensive. Good luck and don't blow yourself...up!
