He'd loaned his 450 to a local WMX rider and I guess it blew up on the leap at Red Bud.She ended up being transported to Ft Wayne hospital.

Yowzer....Hope she is OK.Last I heard she was still in ICU, but mostly just to keep an eye on her. She's been on facebook so it can't be to bad.so she is still critical?

gotta keep those race bikes in tip top shape day in and day out... no exceptions

Don't know why the bike blew and not saying that this is the reason why.......but maintenance isn't something to be dealt with lightly. Especially when you're hitting jumps, if the bike locks up in the air (which is what happened here)....

Some engines just go when the go. 
most bikes lock up while in full song. Either in a straight or an over rev in mid air. Or in my case while in idleSome engines just go when the go.

Jax, in your bearings defense, it was 10 yrs old...
you are supposed to totally rebuild these motors once a year as part of the maintenance. not saying the bike was neglected...

Uhhh thats exactly what you are saying![]()
but I am sure he doesn't rebuild his every year either.
