Ethanol
Hello everyone ,what a beautiful day in Kansas it was to ride today. I'm learning everything about my new Road King, Before I took delivery I found a gas station that has premium with no ethanol. Reading through the owner's manual it makes you believe that everything on that motor is setup to run ethanol and that you need to use it. Is it possible that with all the electronics that are set up we really need to use the ethanol fuel? I was going to stay completely away from it because of what it does to my small engines and yard tools. The damage IS unbelievable. What do you think?

Ethanol won't harm Your Harley.I have only run non ethanol several times in last 3 Harleys.Combined 80,000 miles.I used no ethanol to see if I could get better gas mileage.The test was done in Florida comparing My bike and another comparable model.Conclusion: no difference using ethanol or not.Same mileage was found.I do not run ethanol in My small engines because it disintegrates gas lines.

Everyone buys 11%+ ethanol fuel?
Ethanol fuel only absorbs water in East Tennessee?
Ethanal fuel only goes stale and brown where I live?
I could go on.
I have read many of your posts over the years and they are mostly on point, was this post serious?

Ethanol(10%) will not damage your Harley. It is designed for it. Will it run better and get better mpg on pure gas? My2011 Road King does.

When running no ethanol fuel your going to need to let the ECM adapt to that fuel. I do not know what the results for mileage will be, but do not expect to see any change for at least a tank or two, while it adjust to the new fuel.
