If the problem is that there is not enough heat getting into the carb and the heaters on the bike aren't upto the task is it possible to get some sort of replacment heater or to piggy back whats already on there?

Resulting in warm air intake and moisture free fuel-------might work

warming the air up will not prevent carb icing, you have to warm the body of the carb

carb icing is basicly the same thing as choking the carb, ice builds up in the carb and reduces the amount of air that can pass.

the ice that builds up is from the humidity of the air and nothing to do with fuel

Here's the thing though, with SVs you can literally have 2 bikes parked side by side and ridden over the same journey in exactly the same circumstances, one suffers icing and the other doesn't. I've never suffered it at all despite doing a lot of riding in absolutely prefect icing conditions, which makes you wonder- why not? Why is it that one bike has problems while another powers on?

I don't have any actual solutions, natcherly

Although one thing you see mentioned often is to move the sensor for the carb heaters- sometimes it ends up stuch somewhere warm and so fails to switch them on. Checking the wiring and connectors could be worth doing too- thpugh I tend to agree that they're pretty much irrelevant.

If I suffered it, I'd be looking at borrowing someone who doesn't suffer it's carbs... I know that logically that should be no difference, but something does, and logically it's got to be in the intake side of things.

Am I right to assume this icing issue restricted only the carbed versions of the bike and the later fuel injected versions are fine?
