| it was just waiting for all the oil to slide back down the bottom.
as long as when he rode it back the light was out, I cant see there being a problem.
tell him to put it out of his mind.
other wise what does he want to do. split the crank in half to replace the bearing because it fell over ?
those are the only two options, I would just worry about fixing up the body work and enjoy riding it again |
