It appears to be leaking from the lower. Where the leg presses into the cast lower axle/caliper piece. Oil is welling up around the the bottom of the stansion tube. I just finished wiping it up and blowing it out with compressed air and when it pools up I will post a few pictures. And no there was not a trail down to it from the seals. Anyone ever heard of this?
I think my right fork leg is leaking, WIERD

There are supposedly "blow proof" aftermarket seals, but I would say that they are probably just as succeptable as the stock seals, its just one of those things zx10r owners have had to live with, unfortunately!
Good thing for me, Ohlins forks use good quality seals:crackup:

Check the back of the fork stancion, I was almost positve I had a leak out of the adjuster, and did the same thing as you, wiped off and watched, it ended up being the back of the seal and trickling down the stancion and pooling, had me stupmed, cause it was very minor and inconscistent.

There are not many choices as far as oil seals go for the stock Kayaba fork (KYB43). They are notorious for leaving a film on the fork legs and for some, like yours, will leak severely. All Balls Racing makes seal replacements for the OEM but a lot of people have said they're no better and leak as well.
I had leaking problems on the stock forks on my '04 at very low mileage, but the '08 so far has been good. It's so easy to replace anyways, that I'm pretty sure I could replace them in about an hour now (not including the time it takes to pull the forks off the bike).

i had the same issue on my second gen at about 10k mi. I was told by the dealer it is the o-ring which is seated at the bottom of the caliper mounts where the slider screws in. The fluid was not leaking down the slider but coming out the bottom as you stated. It was fixed under warranty by the dealer.
Just an update for those who are interested. I got my fork seals replaced AND my fork was indeed leaking from the foot up. The o-ring inside the foot was compromised, its a pretty basic fix if you have or know someone who is familiar with the workings of USD forks. Suffice it to say I had it fixed and she is good to go, no more leaks, fresh oil and seals. If any of you guys need a great suspension guy in Colorado, let me know. Now I just need the snow to go away!

IF it makes a difference i havent heard of oil leaking at the bottom before untill last week. I work at a bike shop and my boss was preping a used ktm for a customer he sold it to, and his forks were leaking from the bottom of the tube. I wish i would have watched him fix it but i didnt. But it did leak from the bottom.
