Hmmmm.   Here's a puzzeler.

Two pistons, pulled from my '07 330's when converted to 60cc, have ring gaps at exh. side.  One has bold arrow @exh. side, the other has 97 with EXH under and arrow.

My newest has 97 and faint EXH and arrow @ exh. side  with the ring gap on intake side.  WTF?!?!?!?!

Two pistons from '07 saws have slight casting bump in center.

Latest piston has a slight recess.

Ever seen this?
