00 CR125 - gap in piston ring to front or back ?

Recommended Posts

Hey,

I'm helping a buddy put a new top end in his '00 CR 125 and I was wondering if the gap in the piston ring goes to the exhaust side, or to the intake side ? Or for that matter if it sits at a 90 deg. angle to either ? I know that the "t" faces up, and that the hole in the piston skirt goes to the intake side but we're not sure about the ring.

Thanks for your help !

the gap hooks over the piston pins on the intake side. there should be a pin per piston ring. any other way and they will spin and hook an exhaust port.
