I have a 99 mxz 600 and need to know what settings the springs should be at for max performance. I took it to a buddy that knows about clutching and while there he took my secondary off and it was set at 6 and the helix was 50 he said or it was written on there. My problem was that I wasn't getting full shift out and only topping out at 80 mph, he says that the secondary shouldn't be set that high and this is why I have a black mark on top on primary. Does this sound right?? and what should they be at?? I don't know anything about clutching but how he explained it it sounds right to me. Any help would be appreciated.
