110 Octane Leaded Fuel

What effect will 110 Octane Leaded Fuel have on my 1977 Bonnie with the original engine intact? Will mixing this fuel with 93 Octane Unleaded decrease the 110 Octane?

There will be no gain in performance at all, in fact 110 burns a bit slower so there will be a very slight power loss.Mixing it with 93 will lower the octane. The only way to see a power increase would be to build a engine specifically for it with much higher compression and-or more overlap with aggressive ignition timing.

I haven't seen a power increase, but the bike does run smoother. Without making any adjustments the bike will idle without stopping and response is quicker at the throttle.
