To add fork oil to a YZ 125, first, ensure the bike is stable on a stand and the front wheel is off the ground. Remove the fork caps and drain the old oil by inverting the forks and allowing the oil to flow out. Once drained, use a measuring cup to pour the recommended amount of new fork oil into each fork tube through the top. Finally, reinstall the fork caps, making sure they are securely tightened.
