To add fork oil to a 1982 Honda Nighthawk 750, first, ensure the motorcycle is on a stable stand and the front wheel is off the ground. Remove the fork caps using a socket wrench, then carefully pull out the fork tubes. Drain any old oil, and using a funnel, refill each fork tube with the appropriate type and amount of new fork oil, typically around 10-12 ounces depending on the model. Reassemble the forks by replacing the tubes and caps, ensuring everything is tightened securely before lowering the bike.
