This was written by one of our members, Rudy. Its a step-by-step and well done. I'd never done one before, jacked the bike up and a couple hours later it was singing like a champ. Follow it exactly, remembering to spin the motor slowly by hand after you think its all done. It should spin fairly easy, if not, dont force it, go back and check.
If you are any way mechanically adept, you will be able to change the belts. The GL1500 is the easiest Goldwing to do the belt change and the big plus is you don't need to remove the radiator to get at them.
