I did a search on this site and found the following:
Standard + service limit in parenthesis
Friction plate thickness 2.92-3.08 (2.Cool mm
Friction plate/clutch housing clearance 0.35-0.60 (0.9 mm)
Clutch spring free length service limit 32.6 (31.1)
The torque for the clutch bolts is 9.3Nm / 0.95 kg-m / 82 in-lb) which ever suits your location.
While you are at it, check that the rod that goes in the cylinder head (for the KIPS valve) moves with ease. There should be none or very little friction. And check the clutch housing and hub for cracks.
When mounting, start with a friction plate and make sure they are oily.
