That was Brock Davidson at a ProStar race, the Nitrous backfired and blew the airbox apart and raised the tank, that was not the first time that happened to Brock
, it also happened one time at Rockingham. He ended up wearing a protective vest when he was racing..the bike that ended up beating everyone was a 1999 GSXR-750 with a McXpress Turbo system ridden by Mark Moisan.
I did sell them both of them pistons...
