110 octane in a 50cc is overkill. The spooge is more of a jetting problem than gas. Also, the amount of spooge will depend on how the rider rides the bike. If he is on the gas, there will be hardly any spooge. If he/she lugs it, there will be more.
As for running a 50/50 mix. The reason most people run race fuel is for consistency of quality! Mixing it with pump gas or buying race fuel from a bulk tank reintroduces the inconsistency of the fuel.
If you want to run race fuel in the 50, use lower octane like 98 or 100. Get it in the 5 gal. cans and don't mix it with pump fuel.
With race gas, you can usually lean out the jetting.
