How do you check the oil level in a yz 85cc?

To check the oil level in a Yamaha YZ 85, first ensure the bike is on a level surface and the engine is cool. Locate the oil fill cap, usually on the right side of the engine, and remove it. Use a dipstick or your finger to check the oil level; it should be within the designated range. If it's low, add the appropriate oil until it reaches the correct level, then replace the cap securely.
