Cold weather needs leaner jetting.
Sorry but that is not right. Cold weather will cause a bike to run leaner, not richer.
My suggestion? Move the clip either one position up or one position down and see if it either improves or worsens. Then you will know whether you need lean or rich. It's a 15 minute trackside job.

Be sure to check the AP squirt. Mine was about 4-5 seconds every time I opened the throttle. Just drowns the plug. It should be around .5 sec. You will need to do the BK mod to adjust it.
Also the disconecting the blue wire might also help.

Black dry sooty, lean condition.........
The colder the air gets, the leaner the bike runs, you need to jet a little richer........
Popping, or a kind of back fire usually denotes a lean condition, requiring richer jetting..........

How cold is it out now where you're at, and what's your elevation? You do have to jet richer for colder, denser air...You need to make sure your engine is running at a normal operating temperature by covering part of rads when riding in temps of about 50*F or lower, as there is no thermostat to control cooling. It's obvious when you touch the engine and it feels nothing close to summertime, when you can actually hold your hand on the clutch cover without burning yourself. Running it cold seems to be the elusive jetting problem and it can cause cold seizure damage and oil sludge formation.

Warmer temps require leaner jetting.
Thin air requires leaner jetting.
Thick air requires richer jetting.
That is the way that it is...........without a doubt.
