Kd60 bottom end
just picked up a project was told the crank was bad.. I havntgot a chance to tear it apart yet. From what i have gathered this is a common problem? What do i need to look for to make sure crank is bad? If its bearings can increase the crank? I'm new to bikes but been around cars my whole life. Is it worth fixing? It was free so I have nothing in it at this point.
