I bought a '99 Honda CR125 with no compression. I took off the cylinder head and cylinder and found out that the piston took some beating. The connecting rod is a Hot Cam and the piston looks aftermarket. Could the damage be from an incorrect sized piston or slop in the connecting rod? There is not any play up/down in the connecting rod but there is some side to side. I want to make sure that installing a new piston and cylinder is going to resolve the issue.
Any help is appreciated.

Check cylinder size and the piston to cylinder clearance.
Crank sounds ok.
Like said, change the crank seals.
FYI: Hot Cams do not make cranks, so I have to think it is a "hot rods crank.

I would follow Pauls lead and replace the crank seals, along with a new top-end (new Nikasil/piston/ring). Seeing how it's a new bike to you I would also check the jetting against stock numbers and dump any old gas out of the tank and start fresh.
