Here's a good starting point:
Super hard spring
9.35mm from the top of the shaft to the nut
Gray shoes
Lightened centifugal shoes
.4mm gap
OR
JP spring
9.1mm from the top of the shaft to the nut
Gray shoes (red clutch shoes with JP aluminum bell)
Lightened centifugal shoes
.4mm gap
As for the different tracks, too many variables; length, traction, 2-speed shifting point, etc. Try these first and adjust as needed.
