Cooling system

The coolant level should be checked before
each ride. In addition, the cooling system
must be bled of air at the intervals specified in
the periodic maintenance and lubrication
chart.

WARNING
Do not remove the radiator cap when the
engine is hot. Scalding hot fluid and steam
may be blown out under pressure, which
could cause serious injury.
When the engine has cooled, place a thick
rag or towel over the radiator cap, and
slowly rotate the cap counterclockwise to
the detent. This procedure allows any re-
sidual pressure to escape. When the hiss-
ing sound has stopped, press down on the
cap while turning counterclockwise and
remove it.
