Some bikes suffer from it, others don't, it's the luck of the draw i think.
IF it is carb icing then i would imagine the pipes around your carb heater circuit are blocked, which are part of the coolant system to raise the temperature of the carbs to prevent icing, so ideally they need unblocking so the fluid can flow properly.

I had a thundercat that struggled with carb icing a lot, the carb heater pipes were clear and the thermostat worked fine, but the engine just ran too cold in the winter, i used to tape a good 1/2 of the rad up for winter which helped to a point but for the colder times i used pro FST and it stopped the icing perfectly, (although i have to admit i switched to the cheaper option of the same % of isopropyl alcohol, and a small splash of redex instead of pro FST, for the next winter).
Again with 'cats some struggled, some didnt, so i guess some will find FST helps and some won't, but i do know it 100% 'cured' my icing on the 'cat.
