Hi
apple tango - I would doubt it is carb icing as it appears to be happening from cold. With carb icing I would expect it to be OK when started, and OK in low speed riding, and become a problem after running at speed.
Starting it and warming it up for a while would have negligable effect on carb icing, but would help if it is just running lean at idle.
If it is a bit lean or cold then check the thermostat is working OK, and consider blanking part of the radiator off (bodge but might help). Also consider richening the idle mixture up a touch.

Think Pro Boost is just an octane booster.

Carb icing is nothing to do with freezing petrol. It is moisture in the air freezing in the carb. Cold air going through the carb takes heat from the carb body, as does fuel drawn from the carb, resulting in the carb body being so cold that moisture in the air condensing inside the carb and freezing.
If it gets cold enough then it isn't a problem as the moisture content of the air becomes pretty much non existant.
From memory the ideal temperature for carb icing is between zero and 5 degrees.
I have had carbs covered in frost on the outside (where there is far less airflow) due to the heat taken from them, despite the carb sitting just behind that warm engine.
That said, carb icing is very rare compared to the number of times it is blamed for problems.
All the best

I find that if i put in a full tank of fuel from being nearly empty, the motor has a fair bit of extra kick. Fuel fresh from the pumps is colder than whats been sat in your tank for a while, as it's stored in tanks under the ground, nice and cool.
Colder fuel = Denser, but more to the point, it cools the air that it being sucked in with it. ____________________

[quote="Noxious89123
PS: Pro-Boost only has a minor effect on carburettor icing; it is primarily an octane booster. Likewise, Pro-FST
has a minor positive effect on octane rating, but it is not a good idea to use it as an octane booster, because it's a carburettor de-icer![/quote]
Quoted from here;
https://www.silkoleneoil.com/techtip7.htm
So it'll do what you bought it for, it's just that Pro FST would do it better.[/quote]
