How do you change fork oil on a goldwing 1800?

To change the fork oil on a Goldwing 1800, first, securely lift the front of the bike and remove the front wheel and brake calipers. Then, detach the fork tubes by loosening the top and bottom clamps and pull them out. Drain the old oil by removing the drain screws at the bottom of each fork, then refill with the recommended amount of new fork oil through the top of the forks, using a fork oil level gauge to ensure accuracy. Finally, reassemble the forks, reinstall the wheel and calipers, and check for proper operation.
