The bike has been standing for about 6 months and I've just noticed the left fork is leaking from the top dust seal when compressed. I've had the bike about 8yrs and AFAIK these are probably original or old fork seals so probably worn or hardened by now, so question is... If I remove the leg can I just slide out the stanchion once the bottom bolt is removed to get to the seals and dust seal or will I need to dismantle the whole fork leg? The operation is fine and no play in the bushes just the leak to sort out.

Hi .. do you mean the very top dust seal, just above the top yoke? .. if so, I had a similar issue with small oil weeps .. I took off the dust cap, carefully unscrewed the topmost bolt ( the big 32mm hex - it has a spring underneath) and then just put two wraps of plumber's tape (PTFE) around the topmost threads of this top bolt .. this avoids any PTFE getting into the suspension leg itself .. bolted it all back down and it's now fine until I get round to rebuilding the forks later this year
No its the top of the lower fork leg, the dust seal is just that it's the seal under neath that's leaking.
in which case my tip is utterly irrelevant

You need to remove the dust cap,
Then remove the seal retaining circlip,
Then You could,gently prise the seal out.
Or remove bottom bolt and pull the lower leg down,
You’ll need to use the lower leg as a slide hammer to pull out the top bush and seal together.

If you do it the 2nd method,heat the top of the lower leg with a heat gun ,hopefully the bush and seal will come out easily.
If the seal is badly corroded be aware that this method could damage the bushes.

Thanks Mike I've been through the Haynes Manual and its a complete strip down so you have confirmed my thoughts. I'll try both warming and slide hammer approach.
Might be as well to do a full strip down and clean out, replacing the seals and bushes as needed. It’s not a difficult job compared to modern forks.
