bores looking like its nickel so I might just get away with rubbing it down and putting a new piston in

I would find out what your current piston to cylinder wall clearance is, and have the inside of the cylinder measured, before just "rubbing it down and putting in a new piston". The pics of your cylinders plating are questionable whether it needs to be re-plated or not.
I'm not sure what the maximum/minimum service limit wear is on the 94, but you should be able to call your Kawie dealer for that, or you might find that info on here.
