Jetting for YZ 125

I have a 99 yz125 and was wondering if I have it jetted right. It runs great and has lots of power where it should, but it smokes a little. Don't get me wrong, it's not billowing out of the pipe, but under full throttle accelerations, it leaves a little smoke behind. There is also a little spooge coming out of the silencer, it too is not excessive, but just a litte. Is all of this normal, I mean, it is a two stroke and it does burn oil. I was just wondering if I needed to lean it up a bit or just leave it alone.

I am running Silkolene Pro Comp fully synthetic with premium pump gas at 40:1.

Thanks for all your help guys!

Thanks motodawg! Colder air means a denser air which translates into more oxygen in the fuel/air mix thus creating a leaner burn right? Correct me if I am wrong!
