I agree with Gary. If the E10 fuel is in a vehicle that you use regularly, and you use the fuel in the tank up every month.....you shouldn't have any problems. The ethanol issues show up as corrosion when the fuel is not used regularly and the fuel get a chance to begin to decompose. In a climate controlled environment the degradation is delayed a bit - if the bike is stored outdoors and subject to the heating/cooling/moisture swings the problems can show up pretty quickly. The big issue is when the gasoline portion of the fuel in the carb float bowl begins to evaporate, and the concentration of the ethanol in the float bowl increases.......the ethanol is corrosive to aluminum and also absorbs water from the atmosphere.

If you are going to leave the bike stored for a while - drain the float bowl to eliminate the chance of corrosion in the carb.

STA-BIL. I get it at Walmart. Most motorcycle dealers sell some other types that are supposed to be made specifically for motorcycles. The alleged damaging effects of ethanol (E10 gas) on small engines are well documented, albeit controversial. Previously, I owned a Yamaha XT225, which would not start if untreated gas (E10) had been left in the carburetor for more than a week. I got frustrated with it and traded it off before I found out what the simple problem was. Manufacturers claim newer engine designs are not affected.

Thanks! I will give it a shot since the engine is new. I want to start out right.

It's a pure genius thing to
Raise a crop
To make alcohol
Genius..
Making alcohol from waste
Provided transportation costs don't eat the value of it
Makes sense.
I wonder what pesticides get used on the Non Food crop.
How many people are making a living, how many tractors, how much fuel, how much water,
I don't think it's anywhere near the benefit we were told.
But, that's critical thinking.. and not many people engage in that.

Ethanol requirements are and have always been a gift to the grain belt, and, by extension Monsanto. Corn is a stupid crop from which to make ethanol, but we're really really good at growing it, particularly in "Round-up Ready" form. Between the corporate dollars backing it and the early timing of the Iowa primary, neither party wants to touch it.

You can run E85 in them you just need to flush the card at the end of the year or take it apart clean it and put it back on it will run cooler and make a Lil more torque but you will have to rejet it to run E85. Running E10 the problem is people let it sit in the tank and then it eats ship if you're not running it enough or let it sit all winter I delete stuff up but if you're riding it through the summer and then when you go to store either put 110 race gas in it with LED and run it through the carb little bit or put 91 clear no ethanol for storage I like using the 110 race gas because it Lubes everything up so it doesn't dry out
