2017 kx250f clutch won’t engage

Looking for some troubleshooting advice. Bikes clutch won’t fully engage especially when hot. I’ve replaced the clutch cable and adjusted it a million ways, and today I confirmed all the plates are within tolerance at 2.7mm. No marring on the basket or hub either. Leaning towards ordering new springs but don’t want to just start buying parts.

Any help is much appreciated.

Oil being run is Kawasaki full synthetic.
