As above, possibly available to replace easily.
Generally though, they work well with parts in good condition.
Obviously a new lifter plate needed, set of EBC plates is good start point too. F2 model (the original not later re-use of name) from last SOHC 750 build used stronger clutch springs that can be substitute for softer original. They give harder bite to original clutch pack but with stronger leaver pull.
Assembly of lift plate, tighten carefully with 1/4 drive socket set, pulling each one down equally as you pull plate tight in parallel to avoid snapping.
They "snag" if you've not got the alignment right as the assembly closes, you can feel this with small ratchet leverage as it bottoms out early STOP there and back out the bolts to check you've got it aligned properly. Don't keep winding them in and hoping. You may have to wriggle the plate you're pulling through from the rear by tightening to ensure it sts into engagement on its drive splines at the back of clutch pack, and not nose to nose on those spline.
Sounds more complex than it is, but taking time and care with carefully observation avoid damage. They're not big loads as you tighten and should bring suspicion if there's much in the way of resistance doing this.
