1980 Goldwing Interstate 'Back on the road again' restoration

Definitely have a theme song for this one. As I mentioned in the new member intro, this 1980 Interstate was my dad's, he bought new in '80, and took it out West for two weeks each year for a few years. THE PROJECT: Restore it to solid, safe, running order and ride it next Summer to the same destinations (Black Hills, Montana, Wyoming, Dakotas, etc) from Indianapolis. THE REASON: In 2020, the bike will be 40 years old and my dad will have been gone for 20 years. Double the reason to make this happen.

So far, I've done the very basics- new battery, replaced oil and filter, added fresh fuel, and it turns over just fine. Tomorrow I'm going to put new plugs in and if it doesn't fire, check for fuel flow. I can't find the shop manual he had, but I'll get a new one and have to re-learn the pseudo fuel pump system Honda has on these. I used to have a 1981 CB750 Custom and it had the same setup. I know nothing about the shaft drive and how to maintain.

Check out the K&N air filter he had with his handwriting on it.

More to come, but for now, these questions to the group:

What input do you have regarding flush/refill of coolant?
How do I go about maintaining the shaft drive?

Thanks!

What a great project you have on your hands. I'm not a "wrench" guy so I would be lost. I don't think there is a lot to do with the shaft drive. I drained the fluid from my 98 GL1500 and then refilled with Honda fluid. It was not hard even for me but if the seals are leaking that's something someone else will help you with.

Good luck on the project and can't wait to see the completed job..

The shaft drive splines should be lubricated, but I don't know the interval. One other item that is frequently mentioned is changing the timing belts. Hopefully some of our members that are familiar with the older bikes will respond soon.

The belts are probably not worn out, but could be aged beyond service reliability. Greasing the splines on the driveshaft I believe requires disassembly/removal of the shaft. A thorough inspection of all rubber hoses and seals is not a bad idea either.
