I don't do clutchless changes (is that a good or bad thing I  
wonder...?).  So far, the bike has been serviced by Jack Lilley - so  
I've not had chance to inspect oil condition.  But they've not  
alerted me to anything dodgy.  It is a long way to next oil change  
(5000 miles - so probably not due until mid / late summer at  
earliest).  Should I do an oil change 'just in case?'

I've rebuilt engines in my past (including a engine-parts-engine job  
on an XS500 motor many years ago), but so far resisted taking bits  
off the ST - combination of not enough time and a lack of desire to  
end up with three bolts and a circlip in the parts tray when I've put  
it all back together again...  But maybe I should get back to doing  
such things - I suspect Jack Lilley would be thrilled to charge (a  
lot) for such exploratory things...

I guess I was hoping that either this is common or not common, either  
as a symptom of something dire, or as a 'charming quirk' of the ST...

Best regards
