Hey Guys thanks for your quick responses (sorry ive been a little slow!)
I got some pictures of the offending articles:
bits 037.jpg
bits 027.jpg
bits 036.jpg
bits 034.jpg
bits 031.jpg
These pics are just what I managed to pull from the tank with a magnet on a stick - it was trying to clump together so I tried to get some pics through a microscope to show the real size of the bits.
They have the consistency of "metal sand" and there are no large chips.
I got a chance to drain the oil yesterday and look at the filter,
with the oil in a clean drip tray I passed the magnet all through it but only picked up a couple of tiny bits (nothing to worry about).
The filter did have some more metal sand in it but it looks like the majority of the stuff has settled in the tank.
The oil its self looked relatively new (dark but not black).
The engine runs well and I haven't noticed any odd noises in any of the gears (encouraging!).
I'm thinking its not as bad as I first thought now but im going to keep checking things anyway, ive left a magnet on the end of the drain plug and will change the oil a couple more times as well as some more tank fishing.
How hard is it to open up the oil pump? (is it buried deep within?).
Im starting to think that it could be normal wear particles that nobody in the bikes previous life has bothered to clean out (or possibly that's hopeful thinking).
Either way thanks for your replies!

Oh one more question (possibly a stupid one) how do you know the exact model type you have? (4PT ect)?
