I was told by scrappydog scooters that stock sets come pre gapped. Hope they are right

Can someone tell me the stock gaps for a 57mm piston in mm. I heard 4mm. Not for sure. 1st n 2nd compression rings measurements. In not good with math lol so a direct answers in mm would be ideal. It's for a 150gy6 engine

Alright thanks. Had no idea. Didn't want to throw it together then risk damaging the piston or block

Do the ends on a oil expander ring point up or down? What's the difference if so......on a gy6 150cc
