03 WR 450 Conrod Fault

My brother just destroyed his 450's engine. At first we thought he lost all his water but theres no sign of scoring in the barrell and the bike was going fine right till the end. I heard a rumour that is was a factory fault, the conrod wasn't hardened properly and this has happened before. Anyone else had/heard of this?


This is the first time we've heard about it hear. Sorry to hear about the bad fortune... :thumbsup:

Is that the part connected to the conuter valve :thumbsup:
