My friend and I where riding today when his 2000 blaster blew up and cracked the case. The blaster has a full fmf exhaust system, no air box lid, uni fliter, oil injection block off, vito's high comp psiton and gasket kit, and all the proper jetting. He runs 93 octan with AMS oil at a 50 to 1 mix. Could you tell me what could of went wrong, what I need and where to get it. Thanks. Also we would like to get it running by Monday the 25th.

 

The vito's piston.

Where did it crack the case at?

 

At the bottom of the motor abiut in the middle.
