Running too rich and having oil come up the vent tube seem to be two different problems. One is related to crank case pressure, the other related to your tune (hammer drag map).
I definitely think finding a quality tuner in your area and getting the bike custom tuned will help with running rich and mpg.
As for dirty tb, first make sure your oil level is correct, not overfilled. If no one else has any better solutions, maybe you could add a catch can, that can be emptied periodically so that oil doesn't actually make it into the intake. I know it's not a sexy solution, so hopefully someone else will give you a better idea.
