Have read all the posts on chains with interest. I use good quality lube every 500k and also clean with kerosene on a regular basis. After reading this starting to think I am wasting my time. Changed last chain at 25,000k but will try for 30,000 with this one although I guess your sprocket wear may be affected. Anyone with the x ring fitted have any report on increased mileage with them instead of the o ring?
