Always good to bring a bike back to life. One thing that's common on the vintage Goldwing site is to run a 50/50 mix of oil and ATF in the sump for 20 minutes at idle. That does a nice job freeing up rings and generally degunking your engine. My 79 smoked a lot when I started it up the first time. She hadn't run for probably 20 years. I did the 50/50 mix and it really helped with that a lot. Just remember, don't ride it with that mix, only let it idle and then dump it. Looks like you've got the basics covered. Just include ALL the fluids when you change them out. Don't wait too long on the POG either. Hate to see your hard work go for nothing if she seizes up on you.
