Ethanol fuel is fine... until you don't ride the bike for a while. As moisture is absorbed, the ethanol gets saturated (it can only handle 4.5% water), and we get what is called phase separation... the excess water sits at the bottom of the tank and causes starting and running problems... you call it "bad gas". Starts happening in a couple of weeks.
The other thing that happens is a gum film builds as gasoline evaporates... BTW, pure gasoline will not degrade for a couple of years in those tank farms. The ethanol and additives are added right before delivery to the oil company's specifications, and the tank truck makes its way to the gas station.
Dumping in Seafoam does two things, the naptha is a slow-acting solvent that dissolves gums, the isopropanol can disperse a large amount of water, many times what ethanol can. So that's why it works. It happens to be a good stabilizer. Naptha is in lots of stuff, GooGone, WD40, wax removers, etc.
So doesn't hurt to use some Seafoam once in a while, and especially if you have "bad gas". If you look up the MSDS for the product you use as a fuel conditioner, you'll find most contain mostly naptha. "Injector cleaners" add some harsher solvent like Benzine, etc. in a very small amount. Then they stick a fancy label on it and market the heck out of it so you will buy it. Seafoam at one time was marketed as "Mechanic In A Can". I like it because it's simple.
You can do your own research..... every time you hear of a snake oil, go look it up and see what's really in it.
Keep yer stick on the ice....
