Great report !!Keep it coming!!
I am glad you saw a wolf.I love wolves also and hope to see some in the wild .Maybe next year in the Upper Penninsula of Michigan I can spot some.
Too bad about the KLR.Has any service been done like adjusting the valves in the past?
Maybe the cam caps did not get tightened properly during a valve adjust.
It looks like the cam cap bolts loosened and allowed the cam to ride up in the back and allow the decompression mechanism to kiss the valve cover and explode.
Good luck with the KLR,at least its a simple bike and parts are pretty cheap.
