Darrsi, the sentences "So frequent use of your bike should keep the problem at bay. Also filling up from empty rather than topping up often with a fiver's worth will mean the fuel is fresh rather than a blend of fresh and stuff that's been in there for months." were meant to be read together. If you're putting half a dozen litres in at a time the percentage of old fuel in there is far higher than if you wait until you can fit 18 litres in.
By "the problem" I was referring to the phase separation of the fuel, rather than carb icing. The only time I've experienced that on the Fazer has been when the pipes carrying the hot coolant round the carbs have blocked. If your heating circuit is OK and you can only avoid icing problems by dosing the tank with pure ethanol then I wonder if more than just atmospheric moisture is the problem. Perhaps the filler cap drain is allowing water into the tank rather than piping it safely away?
Anyway, the OP's problems are not likely to be caused by icing in this weather, AdieR hit the nail on the head when he suggested it's probably trying to run on something that's more akin to gritty beer than petrol. :lol
