Coolant The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
To check the coolant level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:_

The coolant level must be checked
on a cold engine since the level
varies with engine temperature.


Make sure that the motorcycle is
positioned straight up when
checking the coolant level. A slight
tilt to the side can result in a false
reading.
_
2. Check the coolant level in the
coolant reservoir.NOTE:_ The coolant should be between the
minimum and maximum level marks. _
3. If the coolant is at or below the min-
imum level mark, remove panel A
(See page 6-7 for panel removal
and installation procedures.), re-
move the reservoir cap, add cool-
ant to the maximum level mark,
and then install the reservoir cap
and the panel.
