SOLUTION: Buy 5 litres of 99% pure alcohol off Ebay, for about £20 delivered, and put 200ml in every full tank of fuel.
Carb. icing only happens between 0 an 5 degrees temperature by the way, not normally below or above those temperatures!
The alcohol lowers the freezing point of any moisture, and also binds with water in the tank then burns it off.
My bike has never suffered from it since, and the alcohol burns quite happily with petrol with no side effects whatsover, other than the good one!
Make sure it's 99% though and not the 70% one, as the other 30% is water, and you obviously don't want to be sticking water in the tank.
ps: The water pipes of your carb heater circuit are probably blocked too, as i know they block very easily as the pipes are just too thin, and every time mine have been checked they were blocked!
I'm pretty sure they put alcohol (5-10%??)in unleaded fuel these days as standard. And not everyone's happy about this apparently.
So, not sure i'd want to be adding any more personally, but each to their own i guess.
Ps. never use my choke either unless its a cold day.
