The left-hand fork seal on my ST has been weeping since last summer - I thought I might replace them both over the winter, but haven't got round to it yet. Searching for a 'how to' guide, I saw that some owners had used Wynns Autobox 'seal restorer' to good effect. So....I bought some, and one of those Seal Buddy/Seal Mate bits of plastic. Dust cover prised up.....bit of plastic run round the seal a couple of times, 10ml of the restorer applied to the fork leg around the top of the seal and left for a couple of days, then wiped off......and its done the job! Had a (very cold) run out today - no weeping at all. Time will tell regarding longevity, but others who've done it seem to have had long-term results.
