Arctic Cat ZR 580 Clutching Question

I’ve got a 1994 Arctic Cat zr 580. It’s got a Black, Black magic primary spring (116/262) with 51.5g weights. The secondary has the Arctic Cat yellow spring for this year in the middle hole, and a 53 degree single rate helix. I’m engaging at about 4k and tops out around 8000-8200. I’ve read a lot of threads and most agree 5k is where you want to engage for good torque. How would I go about getting it
Up there? I know it will have to do with the primary, but is it a spring change or weight change?

I’ve also got a basically brand new belt on tbere. Ran threw a tank and a quarter of gas with it on so is worn in I think by now. Today it was climbing almost to 9000rpm so I made sure not to go WOT but riding it home it finally started engaging at 4500 and pinned it once before heading back and it looked to be around 8100-8500

Why the changes if nothing was changed?
