one of the thoughts i had concerning fuel atomization and weather or not to polish the ports was this:
leaving the intake slightly rough does encourage a small amount of turbulance that in it's self, atomizes the fuel mix. as is the practice on car engines and other 4-strokes.
we are dealing with a 2 stroke engine that has a very fast spinning crank, and a not so direct path to the cylinder that the air charge must take to get there.
therefore, polish those ports because it needs all the help it can get!
just my $.02 thought on it.
