I was also dissapointed to not find this in the owners manual, I would consider the clutch inspection a maintenance item. Anyways I have had my cover off and clutch in and out numerous times, I tightened the pp bolts till good and tight, clutch cover I just tightened till snugg as the cover is wafer thin. Hopefully someone with a shop manual responds to this with the right specs for future.
Did you use the spring and small friction disk first in? I originally did not (used a standard friction disk) and had lots o squeeling when engaging under load. I swapped the small friction and spring in last weekend and will test tommorow to see if squeeling goes away.
