    Clutch, 1983gsx es750 engine,what is the purpose of wavewasher below clutchplates?

    Hi

    When comparing the clutch in the 1983 gsx 750es engine
    the bottom of the innerhub below the clutchplates
    have a wavewasher that looks almost like an extra steelplate
    and also a lock/snapring in place
    that the older clutches don`t have.

    What is the purpose of this "extra steelplate" hub?
    does this design have any advantage compared
    to the 77-78gs750 style hub?
    Do all the later engines have this type of hub?

    In advance
    Thanks
