If you can get gas without ethanol you may not need to make any adjustments. Ethanol in gas will lean the mixture in a bike with carbs, as will cold air. Just going to ethanol-free could richen it up enough to make it run better in cold temps, but it would be rich when it got warmer - so you'd need to make an adjustment then.
Overall it's a good idea to stay away from ethanol in gas if you can. A completely stock cycle will probably run better (slightly richer) with ethanol-free gas. One that has been tuned properly for gas with ethanol might need slight tuning when going to ethanol-free.
