Tilt the motorcycle up off of its kickstand until it is vertical so that you can check the oil level through the sighting glass.
The oil level should read somewhere between the "Low" and "Full" marks.
After starting the motorcycle and rechecking the oil level, you may add or remove oil as you see fit, then place the oil filler cap back over the oil filler hole. Turn the cap clockwise until it is snug.
