Another winter tip we live by around our offices is the mandatory use of isopropyl alcohol fuel de-icer in all of our rides during the winter months.
This “trick” is no trick at all and will ensure your wheeler starts and runs in cold temperatures. There are no ATVs in service in winter climates that do not accumulate some water in the fuel system. Water will eventually become ice in freezing temperatures and will limit or completely obstruct fuel flow.
If you see black smoke on cold starts it’s an indication of water in your fuel. Don’t take any chances – use only isopropyl alcohol based gas line anti-freeze, not methyl hydrate (it will say so on the label) in your fuel throughout the winter.
