Must have been a mess. Gotta believe the pan, panel, and clutch guard are not like new, either. Sounded like both the primary and secondary are trashed, and both should get replaced by the dealer, either poo's warranty or theirs, for poor PDI. Hopefully the stub on the crank is ok, and the broken bolt came out easily, and the leader is taking care of you. Where did the bolt break off, at the stub end?
Likely a non-torqued bolt, or maybe not re-torqued after spinning/stopping the track. Unless it's a defect. Have seen the fixed half break, but don't recall hearing of any bolts breaking in the last decade.
