Polishing things on two stroke...

Being lazy I have never bothered polishing the ports and rarely match them. I build them for durability, and a solid, trouble free 65 mph horizontal Zuma motor is good enough for me. Moped Army has a very good section describing what to polish and how to match ports. My friend did it to his motor, and even with a almost identical build he will hit 70 mph and get me off the line. Is your Aprilia the one with the EFI, or is it the old school carb model? Liquid or air cooled? Friend had a Derbi Predator liquid cooled once. That thing was FAST!
