40 ft lbs
This bike takes about 3.7 quarts.
'79 is a 1000 cc , '80 is a 1100 cc. You would have to compare the both. Or check with the parts dealer.
10w40 will do just fine. I use Motul.

1980 was the first new version of the Goldwing Interstate. It came with the 1100 engine. That lasted till 1983, then the "84's came out with the 1200, good till 1987, then the 1500's. The 1980 Interstate all dressed cost me just $ 5,000.00 here in Canada, those were the day's.
The best way would be to pick up a manual. Just too many things to do.

The Specs was created in 1980.
If this is still the same as up to 1986, then you have to remove the left side exhaust, left side crash bar, gear shift, and removable sub frame. Theres your starter. Good luck.
