John Weaver Crash @ Bakersfield

Hi all.
I was just looking at some pics from bakersfeild race and
looking at the John Weaver T/F crash, my question is this.
After he crossed the finish line the engine looks good and the
butter flys are closed. Now why is there so much fuel coming
out the tank breather ? it looks like enough to wet the tire and
thus cause the crash ???
Just me,
Nitro.

 

Nitro,

John kicked the rods out of the motor on that pass. Thats why there is so much oil on his visor and the slicks and caused him to swap lanes.
