In Oklahoma we have a law that Gas pumps must say if they're selling ethanol blend or 100% real gas. I always get the real gas.
Winter storage Outside, Full tank of fuel with sta-bil and a little seafoam in it. Bike runs just like it did in Nov when i parked it. I finally burned thru the sta-bil mix a few days ago.
Maybe the ethanol blend is the culprit because not everyone who uses sta-bil has the troubles that the OP is talking about.
