I have a set of 1985 250r cases, each side case on the inside between the crank, and the counterbalancer has a notch knocked out of it about 1 inch by 3 inches. I have a guy that says he can repair them by building up the hole with a tig welder I believe, and then grinding it into shape. I told him that I have an old case that he could cut the pieces out and weld into the notches, but he said his way was better. I'm just worried about him ruining the cases. Does anyone have any experience doing this, or having this kind of repair done for them?
