19 KTM 85 sx locked up



So my son was riding yesterday and he shut the bike off went to restart 10 minutes later and motor was locked up. After tearing it down I found that one of the bolts that holds the crank stuffers on backed out and is not allowing the rod to go around. Now I have to split cases and see if crank is rebuildable or just replace it. I’ve never split the cases on a KTM done Honda and Suzuki before. Is there any difference when tearing it down I should look out for? I have a tusk crank puller will...
