    Is the clutch slipping? No? Then they are thick enough.
    Are they the original clutch discs? Yes? Replace them no matter how thick they are.

    Maximum allowable warpage of the steel plates is 0.05mm (replace them if they have blued, regardless of warpage).
    Minimum friction plate thickness is 2.8mm
    Spring free length is 41.2.., service limit of 40.2mm

    I happen to have the shop manual on hand. It's not like I remember all this stuff.

    CLUTCHES 101-Part 1: the 400/550/600s with pics
    The differences for the 650 and 750 clutches are explained in the thread. Most everything is the same though.
