With winter approaching and riding season drawing to an end for some of us, this is when I try to keep 100% gas in my bike. I was close to "E" so when I filled today I filled with pure gas. No Ethanol/ I think between this and fuel stabilizer you have a much better chance of not having issues at the end of storage. I know some will say it is overkill but it only cost a few pennies more. Gave her a bath, put on the Battery Tendaer and tucked her in for winter.
