I talked with Honda mechanic he admitted this O Ring is not available from company
he said we say to company for this Ring but they don't give it as spare part
He suggested alternative is Lifan Cylinder Seal Kit Or Lifan Half Kit In this package it includes
seals which fits to 100 clutch arm
And I also request you to register your complain with Atlas Honda as well 0800 24522
tell them your frustration and difficulty you have faced
