FW: [Ducati] Ethanol blends

[MS&F]

Not sure about ethanol, but we used to run our methanol bikes a lot richer,
like 5x the volume of fuel compared to petrol.  Engines ran cooler and made
more power.

Ethanol should have more available carbons for oxygen than methanol but not
as many as regular petrol, so I would think that you could experiment with
going slightly richer.  I would also think that the oxygen sensor in the
exhaust should pick up excess O2 and cause the mixture to richer
automatically.

So, all you should notice with an efi bike is slightly (maybe 5% ?) heavier
fuel consumption.  I wonder if this happens in practice.

I wonder if there is a way to optimize ignition or valve timing to get
better performance out of this stuff?
