Sluggish controls in the cold

Hey all, I hope everyone is enjoying this deep freeze as much as I am!

In the past couple of weeks, my throttle has been getting sticky in the cold. It will be worst when I first get on, and gradually gets better as I ride. Usually by the time I stop it will be back to normal. At its worst, it will only partially close on its own, but thanks to the double cable system I can close it the rest of the way without any problem. Hasn't affected my riding at all. I have tried various lubes (WD-40, 3-in-1, Break-Free CLP, and even a little bit of stuff meant for machine guns called M-Pro 7 which gave the best results so far) on both the throttle and by dropping it into the cables from the throttle body with various effectiveness, but nothing has cured the problem. Only thing I haven't tried yet is some generic silicone based lube I picked up at home depot yesterday, but couldn't bring myself to work out in this cold just yet. It seems to me to be a primarily temperature related issue though.

I was just outside checking on the bike (it lives in a parking lot unfortunately), and the throttle was sticky like I suspected it would be, but to my surprise the clutch lever is now exhibiting the same symptoms. I hope that when it warms up tomorrow it won't still be sticking, because unlike the throttle the clutch has no return cable I can use to force it shut if it sticks.

Has anyone else run into a problem like this? How worried should I be? Suggestions on lube? Also- the throttle cables are after market ones I put on this summer after the factory cables began to fray. Chrome plated and stainless steel with a coated interior which supposedly does not require lubrication. The clutch cable is still factory original. Never had any problems with either set of cables until this. I hope I haven't made any majorly stupid mistakes.

seem logical to me that even most lubes will have a certain temp in which they will start getting sluggish and gummy

i hear that mobil 1 oil has a very low freezing temp maybe lubing the cables with that could help

here is some interesting reading on the subject

Probably some moisture inside the cable. Hair dryer, dunno.

I use "3 in 1" oil. No problems. Clean the cables out with WD40 ....then oil them with 3+1.

Remove and clean the grease off the bar and inside the throttle sleeve. Light coat of oil there. This might be where it's sticking.

If your bikes left outside its possible there is water inside the cables. Flushing with the WD40 should remove it. Don't cover your bike with plastic, it just traps moisture under the cover.

Update-

Its quite a bit warmer today (almost 30!), and the clutch was behaving normally again. The throttle was still a bit sticky, so I pulled the throttle body apart again and gave it a quick shot of Silicone WD-40. I checked for any dirt, debris, or grease under the throttle sleeve as suggested but found nothing. Gave it a light coating of M-Pro 7 anyway. Also gave the throttle itself a shot of silicone lube. It loosened up a bit after that, and once I warmed up the bike just enough that it didn't need any choke it returned to normal. This has led me to believe the problem is closer to the engine since there's no way any heat had gotten to the bars that early. I'm sure lubing the throttle sleeve and all helped, but the stickiest part seems to be the throttle lever itself (I know that's not the proper term, btw, can someone enlighten me on that?). Hopefully that silicone stuff is the answer! Its what I always used to use in my mountain bike racing days.

Maybe the cover to the cable is just shrinking. I do that when I'm cold.
