Gasoline makes our bikes go. Ethanol is not conducive to a healthy bike. End of story.
Removing ethanol from gas poses several benefits; since ethanol is incredibly hygroscopic (bonds with water easily), it pulls moisture from w atmosphere and traps it. This new blend is heavier than gas, and sinks to the bottom of the tank, where it gets sucked into your fuel system.
Ethanol is also detrimental to rubber pieces and gaskets.
Removing ethanol gives you pure gas. Wonderful.
The procedure is simple: add water to gas.
How you decide to do this is up to you, but be careful - gas eats certain containers, and dissolves certain chemicals in other containers.
Here is what I do:
I have a 5 gallon tank with a length of pvc hose coming off the spout, and a valve at the end. I add a cup of DISTILLLED water per gallon of gas (can't have too much water) and shake the hell out of it. This bonds the water and ethanol. Then, I sit the gas can upside down in a jig, with the lowest point being where the spout connects to the can. I let it sit for a while, and drain out the water, followed by the water/ethanol mix, since both are heavier than gas. You now have pure gas.
Note: removing ethanol reduces octane - use 93 octane to achieve "regular gas" octane. If using 87, get an octane booster.
