old rotor left, new rotor right.




ok so i was rebuilding the motor and the rear rotor was pretty messed (as you can see) so i bought a new one and found out that the previous owner machined the rotors to 3mm. so my question is should i save up and pay for the new rotor to get machined or just use the old one? the reason i ask is because im on limited funds and lookin for advice

 

Spec out the old rotor, see if its still good.
