I was thinking that the speedy was not sounding right. Really poppy. I touched the right side pipe with my boot and it moved. That's bad! Pulled over and found that the header had cracked off from the flange.
Got to taking the pipe off and the frame bracket that the header mounts to falls off. Both welds broken. One weld appeared to have been cracked for a while.

I had only ridden it about 60 miles since coming of its winter cocoon. No idea when the breaks occurred.

It looks like frame rails and header are readily available on ebay. It should be an interesting surgery.
