On my 2nd rideout this year I discovered a few drops of oil on the garage floor and quickly determined a fork seal was leaking.
I tried a seal-cleaning blade that I made myself from a plastic carton (good old YouTube) but, no difference after a few days.
So, decision made; fork seals, oil and some adjustable fork lock stops were ordered from the Brill team at AP.
I already had a fork (dis-)assembly kit from a few years ago when I bit the bullet trying differing springs on another bike so, fitting the seals myself was a bit of a formality; once I managed to find the damn kit!
Let down No1:
After removing and stripping down one fork went very well, I was gutted to find that the fork seals sent from AP turned out to be Pyramid brand rather than the OEM mentioned on their website. I removed NOK seals from my radial forks (which came from an RSV-R). I have had Pyramid seals fail within a year, previously on other forks, to explain my disappointment.
AP however were excellent and issued an immediate refund once I'd returned the unwanted ones.
As luck would have it, I revisited a Fork service video (good old YouTube) from a very trusted tech who mentioned that he now trusts SKF fork seals so, the hunt was on...
The very helpful SKF distributor I found for the UK only deals wholesale but, maybe someone can use them:

Thankfully, they have a preferred motorcycle outlet - dirt bike based but the owner was very knowledgeable and answered all my questions easily AND sent the parts quickly and free of charge
It appears that to Joe Public, only the full 2-part kits are available of scraper and main seal, together.

*KITG-43S for 43mm forks are listed, as an example for a Honda CR125 (1987)
Let Down No2!
The new seal was quite a tight fit inside the fork and I wasn't happy with the previous method I used of cutting and re-using the old seal so, some dedicated eBay browsing paid dividends in that adjustable fork seal drivers are now available to cover a range of fork diameters. Sadly, the idiot seller I chose, let me down in every way possible not in the least, with no reply in any way at all to all my messages. Thankfully eBay refunded me the day after I reported the seller.
Thankfully for me - Machine Mart sell a Laser Tools seal driver for only a few quid more than I paid so, I'm waiting on that before I complete the forks.
Finally, here is a link to the excellent YT video that started the ball rolling:
