hi
iv changed the fork oil in both forks , iv now noticed on one of my forks slight oil on the inner fork , the shiny top bit of the fork , there isn't a lot and its not running down onto the bottom fork , iv used new seals I cant see any bend in the fork or damage but that's not to say its not , should I be looking at getting the fork replaced or will I be ok ? iv changed the seal three times with new seals now and still have the same problem, the forks were clean when I put new oil and seals in it so don't think its down to that ,
thanks for any help

Not familiar with the SV forks (yet) but if the bearings are worn then the seals won't last. On my last bike that made a difference, even the condition of the lower bearings had an effect.

I was referring to the bearings inside each fork, the bearings that allow the inner part to slide inside the lower part. I'd need to see an exploded diagram, but I'd expect to see a replaceable bearing or bushing at the top just below the oil seal, and one at the bottom of the inner tube.

Its not something you can see from the outside. But it might not be called a bearing. If I'm thinking about the same thing as aesmith, its an internal ring or bushing which may be worn or damaged.
You would have to get the upper and lower completely apart to check this visually. If its cracked or worn, the stanchion may not get a good seal or might be rocking around in the lowers. The seals themselves may not be the problem.
Does the ride feel any different at the moment?

Yes. Bush is probably the term, not bearing.

Hope this helps; is it items 8 and 13 here you're referring to?

If it gets worse and you're replacing the seals, you can check those parts for wear while you're at it.

Is there a chip in the fork working area anywhere?
That can drag a tiny bit of oil past the seal every time its depressed
