screw the air screw in and see what it does. If it doesn't fix it then yes go smaller on the pilot jet.
4t out is richer

I'm not following you on this post Jackson? Agreed on the turning the Airscrew in (clockwise = richer slow circuit) but I don't understand the second part of your statement about going smaller on the Pilot which, in fact, would lean the Slow circuit even more? The cold temperature naturally creats a lean condition (more oxygen per volume) thus requiring more fuel to get to an optimal mixture. Am I missing something?
It used to be common practice to jet a bike everytime the temps changed or something like that... My dad used to do it for me per track and depending on the temps would adjust it through out the day to account for humidity and temps.
