Fuel Stabilizer
Store the bike with a full tank of non-oxygenated fuel. If non-oxygenated is unavailable, a commercial oxygenated fuel is acceptable. Note that most oxygenated fuels contain ethanol. Since ethanol is hydroscopic, oxygenated fuel will absorb water vapor during storage. Completely filling the fuel tank minimizes the exposure and absorption of water vapor during seasonal storage. Treat the fuel with a fuel stabilizer, Polaris Advanced Fuel Treatment additive 2881416 or equivalent.
