If you feel the need to drill I would say on the bottom so it won't let liquid in and fill the frame with water. Maybe weld repair the drill hole after. i wonder if you could slosh some rust converter around in there?

I have done that...to be honest I am not sure how well it worked. My feeling was anything to prevent a bad condition from getting worse. Seems to be holding up fine with no problems. Without actually looking who the hell knows for certain. CB750 F2.
