I had to fix one like that for a KLR bud. See pic below with guide (shoe) outside of socket.

Not sure about the sliver, but it does resemble a circlip - typically used to retain the balancer sprockets.

Highly recommend a very thorough inspection of those internals to ferret out any other gremlins from the PO.

When I opened it up, the guide was in the right spot. So perhaps the valve job was completed, reinstalled incorrectly, bolt wore through, then opened again and put in the right spot?

I will measure the chain, it looked really nice though. I need a c clip on the dampener, I think i will take the weight and gear out and look, it seems really sloppy.

Might as well check under the clutch cover too for any surprises!
