I don't know about your particular bike, including typical ambient temperature and altitude, but you've probably got a 34mm CV carb with a 105 main on the front and 110 main on the rear, and a 40 slow jet. You're going to need to increase the fuel flow capability by at least 25% because of the additional amount of ethanol required to reach stoich air/fuel, which means you're going to need substantially larger jets and possibly a larger fuel line and a low pressure fuel pump.
Also, alchohol is much more corrosive, and will attack and deteriorate just about any metal except stainless steel, given enough time and use. It also tends to melt some rubbery products and gaskets, so you'll probably want to replace all fuel system parts that aren't alcohol compatible.
Your ignition timing will need to be adjusted, make sure you don't have too much spark advance.
You'll also want to change your oil more often, there is always a trace amount of unburned fuel mixed with the engine oil and alcohol will damage engine bearings very quickly.
Alcohol won't burn well in cooler weather, so expect harder starts when the temperatures drop below the 70's and very hard starts when it's in the 50's. That's farenheit, not centigrade.
I've been working on alternative fuels in injected bikes, but I haven't had any experience with carbed bikes on the street, only in drag racing. Good luck with the Aero, that's a great bike. If you have additional questions, email me.
