Well, that took quite a while, but apparently she's back to running. I got a call from the shop yesterday letting me know it was ready, but I was out of town and they're closed on Sunday and Monday, so I won't be able to pick it up until Tuesday.
The guy told me when he called that they found the root cause of the top end failure. Apparently there was a small piece of plastic that got into the engine and clogged up the oil injector, which starved the top end of oil and caused the failure.
Since the engine has never been worked on it obviously came from the factory that way. I haven't seen the plastic, but he said it looked foreign, not something inside the engine that broke loose.
Chalk one up to crappy QA at the KTM factory. I'll try to get more specifics on Tuesday and share what I learn.
