Short comments
everyone makes bad deals when it comes to old bikes sometimes and Cars and other things.
Even if you have done it for many years there is eventually a bike where you missed something at the purchase.
Not everyone will admit it .but that's the way it is .
As mentioned I had one Piston looking like that little less damage .. I got away with honing ( Perhaps you wont )
.. The top is off so inspection of top end is possible and feeling the play in the small end conrod. and so on
I did not open the bottom .Of Course inspection for particles in the low filter --- magnet ..and oil pump working
I replaced the Cam shaft bearings .. I do that when I am in there had some on the borderline to explode.
Normal head job .. valves ..inspecting the cam and so on Valve stem seals.
The Crank bearngs are solid and a lot of what is coming loose shavings and so is aluminium so maybe they can take it
Note this is not a recommendation this is how I did it
are bore here is expensive and I am the " last owner " segment so this above described method is not suitable for a mint machine.
I feel that these bikes runs well even without perfect Compression.
As mentioned new set Cylinders and Pistons or another engine perhaps
