Cooling system

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

WARNING
Do not remove the coolant reservoir cap
when the engine is hot. Scalding hot fluid
and steam may be blown out under pres-
sure, which could cause serious injury.
When the engine has cooled, place a thick
rag or towel over the coolant reservoir
cap, and slowly rotate the cap counter-
clockwise to the detent. This procedure
allows any residual pressure to escape.
When the hissing sound has stopped,
press down on the cap while turning coun-
terclockwise and remove it.
