If the plugs are black it would seem you are running way to rich. I would go back on the mains. If it is off, it would be better to be slightly on the lean side as the bike seems to perform better than slightly rich. I just went back on my pilots and mains and the bike is running great. I had a lot of other stuff done though. I would try 125s or 128s. My dealer tunes race bikes and says most all the bikes they redo for more power that have been worked on before, have too large a mains in them.
