I dont know the exct numbers off the top of my head but I had to put the largest weights that yamaha sell with all three rivets in each weight along with a flat washer on both sides of two of the riviets. this solved all of my cluthing problems. I am also riding at the same elivation. my best advice is to put as much weight in the cluth as possible.
