It's not when the fuel is a liquid that is the problem it's when it's turned into a vapour in the emulsion tubes, which under certain conditions can freeze momentarily as it mixes with cold air causing the motor to misbehave a little.

Some bikes seem more prone to it than others and some people say fuel additives through the Autumn and Winter months can help.
I had an oil heater on my 900SS, complete waste of time; like you say its not when the fuel is in the float bowls it needs to be heated. Additives like pro FST do help a bit and I fitted a plate in front of the carbs to deflect the cold air which also helps, partially covering the oil cooler raises the engine ambient temp as well but none were 100% cure.

I gave up in the end sold the bike and bought a 748.
