LT540 sheared flywheel key 

If no one knows what it is or sounds like. Well here it is. Sheared flywheel key on a quadzilla and what it looks like inside when it happens. You can here the bike back fire and it would not stay running. After I pulled over and shut the camera off the bike wouldnt have fire and than would kick back real bad. Only could have been one thing and my assumption was correct. You can hardly see it but the key is cut smooth off flush with the snout of the taper on the crank.
