Main bearing isn't much expensive, so if your one has developed play, change it and enjoy the engine.
I just changed the front one with Sirio original part bearing and its still got that left to right or up and down play. I think I need to change the inner bearing as well, however my LHS doesn't have it at the moment.My LHS however got OS TZ replacement bearing, will this fit? Can you give me the bearing size for the inner one?
