Pull the oil cap/dipstick off of the oil tank.
Using your funnel, slowly pour 3 quarts of oil into your oil tank.
Use the oilcap/dipstick to check your engine oil level (holding the bike level if you have been working with your side-stand). You oil level should be kept between the 2 dipstick marks. After refilling with 3 quarts it should be right to the top one.
