OUCH! DId it knock his hand off, was that his glove, or the piston that bounced forward? I can't make out the details.

i think it was the piston, but im not positive. im pretty sure it hurt like hell, and wouldnt be surprised if it broke every bone in his hand lol

i also have a video somewhere of a guy at the line, and his throttle gets stuck. he ends up taking out the tree haha.

i just watched it like 2 days ago on youtube, but i cant seem to find it now :(

It was a back fire, that's all. It came up though the air box, blew the airbox lid off, broke the fairing, and punched his hand.

the piston, had it actually come out of the engine, would have gone though the radiator... after it went through the head. if it were even possible, it would have been a spectacular explosion. fact is, it doesn't happen. the piston usually fractures and shatters inside the sleeve.

My fiancee was trying to start the EX last week after forgetting to put it on the battery tender... chug, chug, chug, BANG! Biggest backfire I've ever heard, it scared my fiancee to death.

Charged the battery back up and started it on Saturday, and it was running on one cylinder. Turns out the backfire blew one of the carbs right off - it was jammed back into the airbox!

Interesting, never thought that could happen.

I didn't try to view the video in question but the old Harley Top Fuelers in the seventies DID blow the jugs off now and then. :eek: They'd pull the studs at the cylinder base flange and the whole cylinder assembly, head attached, would lift, jam on the piston, crash into the top frame rail, bending it and as a result would bash the rider in the chest. I witnessed one of these and it happened right on the start-up rollers. An ugly scene of destruction. The rider was hurting and badly bruised. I don't know if it proved to be any worse later.

this vid is the one where the professional rider is at the drag strip, Blue and white Busa and he pins it, bike stalls out and backfires through the airbox. he drops the bike and shakes his hand.
