Hey scooter enthusiasts, problem here. I'm putting a new piston in my gy6 and need to know the ring orentation. as in which combustion ring goes in top groove, which side of ring is towards combustion chamber. one combustion ring is satin black, the other is shiny. Which ring goes in the top groove? On one side of the two combustion rings there is an inscription:
Does the letter(s) go towards the combustion chamber or towards the crankcase? Thanks dawgs!
