Under 5 degrees could possibly be carb icing, i had it years ago and it makes the bike run like a tractor.
Ideally the carb heater circuit piping needs keeping clear, but the pipes are so thin they clog up easily.
I personally put 200ml of 99% Isopropyl Alcohol in a full tank of fuel during cold times and i've never had a problem since, it also removes any water/moisture from your tank. I've been doing that for years with no issues whatsoever. I buy 5 litres at a time off Ebay for about £14.
As for the other issue, what brand of air filter are you using? It sounds air related to me, possibly either an air leak, or a blocked or cheap crappy filter.

More people are born because of alcohol than will ever die from it.
