Yep, probably carb icing, just endured a ride home in sub zero temperatures having to have the choke out for most of the journey to keep the engine running. Rough as hell. Not fun.
Running lean probably not helping, if you've got a normal filter try that as a first option, and check the connections to the carb heaters if your bike has them (they're rubbish, but it might make a bit of difference).
Just out of interest, do any of you fuel injection bike people have this problem? Icing on the throttle bodies/air inlets?
Best of luck,
