WHICH camshaft "snapped," 12BMONEY? Intake? Exhaust?
And, where did the break occur on the camshaft?
Haven't heard of a camshaft fracturing on a KLR650; have seen and documented in pictures a Generation 2 with grenaded KACR (Kawasaki Automatic Compression Release) on exhaust cam, scored exhaust cam caps, scored exhaust cam journal (ruining cylinder head), grenaded valve cover; probable cause: Oil starvation. But, neither camshaft "snapped" in this case, although the exhaust cam required replacement.
Looking forward to your response and pictures posted through the courtesy of justjeff. E-mail the image files to him, and he will post 'em for all to see.
Too bad your otherwise splendid ride was compromised by this surprising malfunction/failure; glad you're back on the road.
