How much does a stock Raptor piston weigh? Anyone know? And is the weight you give with or without rings and pin?

Ever heard of a 101mm piston? I found a 13:1 101mm piston. I was looking for a 13:1 102mm piston but I couldn't find one.

I have heard of a 13/1 101mm, but it wasn't a JE.
I know where you can get a 14/1 JE in a 102 bore size.

If I remember right the 12/1 102mm is 15 grams lighter than stock.

A 14:1 eh, I wonder if you would have any piston to valve clearance issues with that piston and the stageII hotcam? Where can that piston be purchased? Thanks

Anyone know who to go to for a stock bore 11:1 piston? Haven't looked too hard yet but think that might be the ticket for me. Preferably a forged piston if there's one out there.
