what do u mean by looser clearence? the space between the skirt and the wall?
Yes, that's it. Forged pistons expand a bit more than cast do, so they run looser skirt to wall clearnace.

Been using them for 30+ years on both 2 stroke and 4. Great piston!
You CANNOT run pump gas and think your making more power than C12.. You have to rejet so rich so it does'nt detonate thus getting black color at the back of the muffler.. I run C12 and my muffler is grey... Do you know why??? CAUSE IT HAS LEAD!!! Good for the valves and the engine cylinder runs cooler..
