Step 9. Run the engine on idle for about 3-5 minutes to circulate the oil within the engine, then shut it off and let it sit for a minute so the oil can settle.

Step 10. Check the oil level sight glass just below the brake lever. The oil level should be between the middle and upper portion of the sight window. Top off the oil if necessary, then reinstall the oil fill cap and you’re done.
