Catastrophic failure this motor is not salvageable whatsoever might as well be a boat anchor

Just out of curiousity, which engine oil was he using? I also wonder if the motor was burning oil prior to this? With only ~2.5 qts and some of these RZR motors burning oil at an accellerated rate mainly due to dirt ingestion (bad intake boots or filter system) it wouldn't take long in some cases for the oil level to reach the bare minimum. It seems like the generally accepted plan is to check your oil level prior to each day's ride, and in Alba Racing's case, to not use Polaris engine oil.
What else can we learn from this besides your comment on maybe poor engine assembly (head shim)?
