1. Find the oil sight glass. The oil sight glass is located on the left side of the engine, just below the cylinder head. It is a small, round window with a black rubber gasket around it.
2. Make sure the engine is warm. This will ensure that the oil is circulating properly.
3. Park the bike on a level surface. This will help you get an accurate reading.
4. Look at the oil level in the sight glass. The oil level should be between the "F" and "A" marks on the glass.
5. Add oil if necessary. If the oil level is below the "A" mark, add enough oil to bring it up to the "F" mark. Use a funnel to add oil.
6. Start the engine and let it run for a few minutes. This will circulate the oil and help you get a more accurate reading.
7. Check the oil level again. The oil level should still be between the "F" and "A" marks. If it is not, add more oil as needed.
Tips:
* If the oil is very dirty or has a lot of metal particles in it, it is time to change the oil.
* Check the oil level every time you fill up the gas tank.
