Inspection
Check the coolant level in the reserve tank while the engine is
at the normal operating temperature with the motorcycle in an
upright position. If the coolant level is below the lower level
mark, remove the reserve tank cap and add coolant mixture
until it reaches the upper level mark. Do not remove the
radiator cap.
l . -
• Do not remove the radiator cap when the engine is hot. The
coolant is under pressure and could scald you.
• Keep hands and clothing away from the cooling fan, as it
starts atltomatically.
If the reserve tank is empty, or if coolant loss is excessive,
check for leaks and see your authorized Honda dealer for
repair.
