I have a 1999 600sx that hits about 9600 rpm right away when I pin it and then it slowly climbs a few hundred more. The shift speed is supposed to be 8500. It have 8DG00 weights with 13.9 (steel) rivets in the base and 10.3 (Al) in the tip and a y-g-y primary spring. I set the secondary spring to 60 deg, it was at 120, and that lowered it to about 9200, I'm not sure if I did it right but I think so (3 on both ends). Any ideas on why it's still revving so high?

is it piped? or ported? cause that will do it and so will a worn belt or old springs.
It doesn't have pipes and as far as I know it's not ported. The primary spring was replaced a couple years ago but I don't know about the secondary, it doesn't have any markings to tell what stiffness it is either.
