It's not the common clutch rattle that many old Japanese bike exhibit - that rattle happens when the bike is idling in neutral and disspars when the clutch is pulled in (never had that issue on the 1300).
I'll have to take a look at the clutch adjustment - hasn't been that long since the last time I checked it though - I lube the clutch cable a few times a season at which point I check the adjustment - last time I checked was last fall but less than a couple hundred kilometres ago at this point.
PS: Stan - putting this half ton bike on the centre stand isn't for the feint of heart (but I can still occasional manage it at this point)
