I have seen several threads on fork seals but I need to share my experience with you.

I use my bike every day to commute to work.  It is now the rainy season here so every morning and most afternoons it is a wet ride for me.  When I reached home on Friday I gave the bike a quick glance over and noticed oil leaking from the left side fork.  It wasn't raining during the afternoon so the bike was dry.  I immediately got worried and started searching for the fork seal threads.  Somebody, think it was Michnus, mentioned that it could be dirt stuck in the seals causing the leak.  I went out with the rags and gave the stachions a good clean.  There was a lot of sandy grit stuck to it that was flung up from the wet road during the morning's ride.  I could see how the dust covers could not cope with displacing the mud and muck, especially now that it was dry.  After a thourough clean-up the problem was solved!  I also gave it a test ride and the oil leak has dissapeared.  I lifted the dust covers using a Swiss Army knife's tin opener.  It is just the right thickness to easily lift them out.  I cleaned all the muck out and fortunately it seems as if there is no permanent damage.

I have not seen it anywhere or may have missed it, but I think one should give the stachions a quick clean before you ride, especially if your previous ride was in wet conditions.  It could make the seals last much longer.
