VEHICLE BREAK -IN PERIOD
After the break in period the oil injection system provides the necessary engine
lubrication without the need for pre-mixed fuel.
After the first tank of pre-mixed fuel has been used please verify that the oil level
in the oil tank has dropped, indicating that the oil pump is functioning properly. If
the level has not dropped, see your dealer for oil pump bleeding and repeat the
pre-mix procedure.
Fill the oil tank when you refuel your ATV. If you don’t serious engine
damage could result.
