Insert a funnel into the oil filler hole to prevent spills.

Pour 3 quarts of 10W-40 motorcycle oil into the engine. Use one hand to stabilize the funnel to prevent spills.

Be sure to use motorcycle specific oil. There are special additives in these oils, that car oils don't have, for maintaining the bike's clutch and transmission.

Consult your owner's manual if you think your operating conditions call for a different oil viscosity.
