rm 125 piston and cylinder

[sparkysakitas]

ok tearing the motor down to rebuild the bottom end
its a 1990 rm 125
what should i look for as far as having to bore or hone cylinder or if it is ok to put back togther the way it is
also what is best way to check to see is the piston and rings are still good?

Check for Flaws in the pistons and check to see if the rings are cracked or worn out...
