I have been rebuilding my wifes machine which is a 98 ktm 125 exc. I typically drain the oil from the left side drain hole, im not sure why but last time i used the right one which i have never taken out before. Apparantly that bolt had been stripped out at somepoint and somone added a helicoil in. When i went to put the bolt back in it bound with almost no force and a piece of the coil snapped off and fell out. Added oil and noticed the leak and crack when it started dripping out. I have attatched 2 pictures of the crack. It goes all the way through one side of the bolt area out to the edge of the case. This is the drain plug below the clutch cover. So what would be the best way to get this crack cleaned out and whats the best fix? Can these cases be welded? I was thinking about cleaning it out and mabey JB welding the hole plug area and crack off since i always drain from opposite side. Would somthing like the metal reinforced gasket type sealer stuff work? or ever just a good gasket sealer? This thing wont be raced just used a few times a year and i dont want to spend a ton to get this fixed. I also dont want this to start leaking out in the middle of the woods. Thanks in advance.
