I just bought a Kingcat very few miles in awesome shape, it is running a ported Attack, I also just bought a Power claw to install, after what Skidoo claims, (they stopped porting on there 2011 models) same sleds ported verus non ported every time 100 to 150 feet higher climbing with non ported, I no porting makes track roll easier, lightens it up alittle, and not so much snow packed in the skid, I had a ported 159 x 16 Challenger on my mod 2003 9001M and worked well, any thoughts on this subject, I am up in the air on what I am going to do, thanks MADDOGWFO
