Hi Danny, Yes I did 'clock' those parts on ebay but I'm a bit 'wary' about bidding for stuff not in the UK, probably unnecessarily so but there you are, nothing quite like a bit of good honest prejudice is there ?.
Back to your bike, you know that there's a 'filter'(sieve) concealed inside the RH engine cover don't you ?. From the point-of-view of filtering it can't do much except stop any stray nuts and washers that may be kicking about from getting anywhere near the oil pump but then if there's any of those bits roaming loose the motor's rubber-ducked anyhow. The adjustment for the balance chain is also under the same cover. Should you ever feel so bored that you want something to do, get a new gasket (David Silver ?) and remove that cover as by now it's probably donkey's years (if ever) the 'filter' and the cavity it fits in have been cleaned and it might benefit from it.
I've got one and it might be still available, a genuine Honda 'Photocopied' workshop manual which when I bought it from a 'H' dealership cost me the princely sum of twelve quid !. Should it still be available I suggest that you get one, it's worth every penny.
Regards, Dave.
