1. If you are riding your ATV on salted roads, spray down the suspension and brakes with a silicone water-dispersant before trailering an ATV to prevent corrosion caused by the road salt!
2. After each ride, make sure to spray off the ATV and allow it dry in a warm area, such as a garage.
3. Synthetic oil is unaffected by cold temperature and provides instant lubrication when starting the engine. Now would be a good time to switch oils.
4. Keeping the fuel tank full will help prevent moisture from condensing and causing passages to become ice-clogged.
5. Install a carburetor heater. A carburetor heater is an anti-icing device that preheats the air before it reaches the carburetor.

Normal Spark Plug- Looks Grey to Light Golden-Brown Color. This is ideal, and means the spark plug and engine mixture are operating properly. Normal Conditions can be judged by the spark plugs firing end’s appearance. If the firing end of the spark plug is brown or light Grey, the condition can be judged as good and the spark plug is functioning properly.

Overheated Spark Plug- Looks White, Blistered, Melted Electrode. This notes the spark plug heat range is too hot for operating condition of the atv engine or plug is not properly gapped and/or torqued onto head.

Excess Deposits Spark Plug- Looks Bumpy, Chalky Buildup. This should be a warning of poor fuel quality, Improper oil has been used for premix/injected, or you have an oil leakage into combustion chamber.

Wet Spark Plug- Looks Shiny, Wet and Black. Can be caused from Prolonged low rpm operation, Fuel to oil ratio is too rich (oil fouled) or Excessive use of the choke (gas fouled).

Dry Spark Plugs- Looks Black w/ Soot Buildup. Spark plug heat range is too cold for the operating conditions, Ignition system problems causing a weak or intermittent spark, can be an indicator of an air/fuel mixture that is too rich, the carburetor settings are incorrect, or the flame arrestor is dirty or has mounting problems.
