Does anyone do this on their fourstroke? How much of a change do you do? I know cold air leans a mixture, but how much?

I was thinking about going up to a 170, from a 165 main jet for the winter....I ride normaly around 0 degrees....so its pretty cold, I think I have rode around -25 before.....:(

I am running the CT titanium needle with the stock pilot and as it cools down outside I am getting a little more decelleration popping. Turning the air screw should correct this, right? Which way richens it up?:confused:
