What is your jetting now and what issues with it do you have? That's the starting point.
Go 40:1 on premix with quality oil. That's a good place to begin also.

Your setup sound very much like mine,
I am running the oil pump though.

This is my jetting for the PWK and it pulls clean all the way into the red in top gear with no problem on stock gearing.
