Default RE: 140 rx fuel
Hello gays, I have one OS 140 RX, I change the main bearing after 50 flights, How do you know when is necesary to chance the piston ring?
What are the symptoms when the ring should be replaced?
And what about the piston and cilinder liner? When is necesary to chance?


Thanks

Jorge Lozano
