[QUOTE="Uzi, post: 4646974, member: 119192"] I did a lot of reading about closed port stuff and read about other people who've cut pistons to fit and then had them crack or blow apart.:eek: This was a cheap no name piston and the casting on it is super thick. The wrist pin area on it was about 2 times as thick as the husky piston. It made the piston pin c clips an absolute &*(#% to get in. I left the area above the piston pin thicker than stock and the area below on the skirt is much thicker than stock too. I'm going to run it hard like the $100 saw that it is and see what happens if it blows I'll try to figure out why. I still don't have a $150 into this thing so it's not going to be a huge loss if dies. [/QUOTE]
