I am getting ready to smooth out the ports on my sons warrior but before i start i would like to know if its worth the time and effort? I would also like to know the key areas to take down if anyone knows.

Unless your a professional 4 stroke head porter, probably about the only place you could make an improvement would be removing the ring inside the exhaust port. Maybe a little clean up/matching too. Im sure you already know, but just incase, smooth or even polished on the exhaust side, rough on the intake.
