1981 GS1100E - I'm about to give up

You also need to back the timing back to no more than 34 degrees. Ray.

The Dyna 2000 mentions to go between 35 and 40 degrees.
I'm at 37.5 right now.

Is this ok/safe zone?
I'm not looking for power. I would not know what to do with it. Just good fuel burn /economy.

If I understand correctly the closer you are to 40 degrees the more power you get but premature detonation can occur. And the closer to 35 degrees less power. What are the advantages of being closest to 35 degrees?

The more advance the higher the octane fuel you will need and the closer to detonation you will be. If ray says 34 and 35 is the closest you can get, go 35. Trust me, he knows his big GS engines. And you will be able to run regular instead of premium fuel.

This is like computers, every option/question is a different Rabbit hole. To the inquiring mind it's complex simplicity

34 degrees for Regular gaz with ____ octane?
40 degrees for premium gaz with ____ octane ?
