Is this normal chain wear?

The underside of the chain is different to the top..which allows it to mean
 with the sprocket.

This is my chain, from an 81 model so it may be announced as it looks different.....If only I could post a piccie..

andy120t:
..meant to say, may be an upgrade. This is my can sprocket.

..is the chain  running in the wrong but of the cam- chain tunnel. It looks as if it ought to run in the square bit, but may have been routed in the narrower central bit and so came into contact with the head at either side.

Veedunk:
My new parts from David Silver just arrived this morning so I’ve taken a couple of photos…
The chain on the left is the one still in the bike, the chain on the right is the new one.
The sprocket on the left is the old one, new one on the right.
Some obvious differences…not sure if this will be the cause of the problem but somethings not right!

Veedunk:
I’ve just noticed the photos above have rotated by themselves but you get the idea.
