Porting refers to changing the timing, area, and volume of the intake, exhast, and boost ports of a 2-stroke engine. Changing the porting alters the power characteristics of the engine.
Lining things up and smoothing them out would be blueprinting. Porting actually changes the geometry to create something new. Most MX bikes will be ported to give a stronger midrange power and some more top end. Enduro bikes will be typically ported for a little more grunt off the bottom end.
