Looking into a blown GZ250 near me

[DanK]

Hi all, I'm new here, but a bit of a gear head. I'm looking into a blown GZ250 near me - it's a 2005 for $500. Apparently it blew a connecting rod - how terminal is something like that with a GZ250? If it didn't blow a hole in the crankcase, is it mostly likely just going to need a conrod and piston? Or is the head/valves likely to get damaged with something like that? I'm not familiar with the internals of this bike yet, but am going to check out the service manual you have here and see if it gives any hints.

Thanks for looking.
