+1. I reckon Phil (the one in France that is!) may quite well be on to something. The clue is perhaps in this sentence...

With the clutch in (no drive) all the chain slack will be on the top run, with drive engaged all the slack will be on the bottom. If the plastic chain slider has worn through on the underside, when the chain is slack on the bottom run it'll be slapping rhythmically against the swing arm - metal on metal.

If you've got a combo of knackered OE shock, chain, cush rubbers then the lower front part of the plastic slider will take a real hammering (and ultimately the swingarm). Add to that a 14T sprocket (maybe lowering links?) and a heavy load, and the effects will be compounded even further.

Take a look. It might not be the problem, but if it is and you catch it early, all you'll need is the new plastic protector for the swingarm.
