IIRCF< octane rating numbers changed sometime in the 70s, so any number suggested in factory literature would have gone the way of the dodo.

My bikes are 10:1 and 10.7:1 respectively. They both get 93 octane from Shell. They both have EFI and computers, so they likely could make do with other fuel.

My truck book recommends 89 octane but it runs fine on 87. I tried 89 once and noticed not a bit of difference. And I ain't spending the money if it doesn't care. It has EFI and a computer, too.

The '46 Deluxe gets 87.
