PREPARATION FOR
WINTER RIDING
Use of some engine oils in cold
weather may make the engine hard to
start. It may also cause clutch drag
and stiff transmission operation.
Select the right oil for cold weather
according to the chart in the FUEL
AND ENGINE OIL RECOMMENDA-
TION section.
ENGINE OIL CHANGE
Dirt and dust in the oil will affect
engine performance, especially when
the weather is cold. Change the
engine oil before using your ATV in
cold weather (below freezing) even if
the oil that is in the engine is the right
type for colder temperatures.
