Bavarian Motorcycles Centurion not so reliable

Had my motorcycle serviced at Bavarian. A friend noticed that the oil level on my motorcycle is too high. I was under the impression that Bavarian new what they were doing with the oil service so did not care to much about this. 2500KM later the camshafts worn away and left me stranded. When I confronted Bavarian about the high oil level, I was told that this is impossible, even though I saw it and had a few witnesses.
