Does ethanol free gas require a different air to fuel ratio than 10% ethanol gas. If so is it significant enough to need to be adjusted. I read that it increases gas mileage. Does it allow you to accelerate somewhat faster. Or top out slightly higher? Will it still do these things without you rejeting to optimize the air to fuel ratio.
I'm not expecting 20 horses here, just wondering if its technically correct, even if difference it to small to feel.
Did any of you guys feel a diference between the two gasses in your bike?
Chances are, your bike is already jetted for pure gas. Either way, unless you're taking the bike on track days, you'll never need to worry about the jetting differences between ethanol free gas and E10.
Unfortunately for me, the only gas near me that doesn't have ethanol is for boats...... and about $6 a gallon.
2.65 a gallon for 89 octane. At the first wawa in our town vero beach florida. Gas actually has a seperate line like dieseal so its not sharing a hose.This could be in my head but i felt like the top two gears gas more power around 80 mph. Everything else is the same.
Usually I am defending ethanol from mis-information, but for this bike ethanol is NOT a good idea. Almost all fuel injected bikes will be perfectly fine with it, BUT this is a old style carby bike. ie it has a carb full of brass. Ethanol reacts with the copper and zinc in the brass. And in the petcock. Even if you replaced the jets with alcohol steel jets, there is still other brass there. At 10% I have heard it has minimal effect but remain to be convinced.
And the mild steel tank can rust from the inside from increased condensation ( less of a problem if the bike doesn't often have a semi empty tank and isn't stored for periods).
Also some fuel line rubbers can slowly perish from ethanol content. Modern FI fuel line will prevent that.

stay away from WAWA's junk gas here in Florida... Go for mobile if you can.. seems to give best MPG. so you're technically running more efficient.
