How do you check the oil level in the oil tank on a Yamaha PW80?

To check the oil level in the oil tank of a Yamaha PW80, first ensure the bike is on a level surface and the engine is cool. Locate the oil tank, which is typically on the right side of the bike, and look for the oil level window or dipstick. If it has a window, check that the oil is within the marked range; if it has a dipstick, remove it, wipe it clean, reinsert it without screwing it in, and then check the level. Add the appropriate 2-stroke oil if the level is low, ensuring to use the correct type recommended in the owner's manual.
