I am looking at a CRF that had a sub frame and radiator replaced, how can I check the frame to be sure it was not tweaked? It is a complete running bike so any checks can't have me tearing anything down for measurements.

Not sure on how to check the frame other then eyeballing it... Does not take much to tweak a rad or sub if you come down wrong, but I am sure the frame is much stronger.
