each ride.
Checking the coolant level
1. Park the vehicle on a level surface.
2. Check the coolant level in the coolant reservoir when the engine is cold as the
coolant level varies with engine tempera-
ture.
TIPThe coolant should be between the minimum
and maximum level marks. 3. If the coolant is at or below the minimumlevel mark, remove the coolant reservoir
cap, add coolant to the maximum level
mark, install the reservoir cap.
