As i reported in an earlier thread, I found by chance that the lower chain rub block had somehow turned on the sleeve and the chain had been rubbing the underside, well finally today I managed to replace it, not too bad a job, main stand off, L/H Footpeg plate off, then Undo and remove L/H lower rear engine mounting bolt, heres what I found.
