Fork Seal leak

I got brand new seals put in but they're leaking pretty bad. What can I do to stop that? I ordered a seal doc but that's gonna take some time to get to me. Anything I can do -now-?

I have a love/hate relationship with this bike I swear to God.

If you put in new seals and they still leak there are two possible issues.
1. You put in the wrong seals.
2. There's a problem (scratch, dents) with the upper fork tube.

( And possible you somehow damaged them putting them in.)

I'd go with number one first. You have the part numbers from the box they came in?

Not too sure at the moment, Will have to go back in my history but I'm pretty sure these are what I got: https://m.ebay.com/itm/New-Front-For...ss!23454!US!-1

I remember they're definitely the right seals as they were 100% identical to the originals I replaced. It is possible the tubes were scratched but I can't be certain. If they were I'm boned because I can't afford new forks yet. Sigh.

Should be able to see if there's any scratches, maybe put it up on the centerstand to extend the forks. You can pop the dust seals up for a better look.

Will do that for sure. I'm sure I can fashion up a homemade seal doctor in the meantime.

I've had 2 new sets leak. One was All Balls too. OEM never leaked for me.

I'm going to look after work tomorrow to see what it might be. If there's no scratches or dirt to speak of, then it's the seals themselves. Which, then I'll have to figure out how to replace without a jack.

It's possibility. Is there a way to tell if they're upside down? Also when I took the old seals out it was nasty and muddy even, so would dirt cause such a leak?

Spockster beat me to it. They can get installed upside down. And if I remember correctly (its been 2 years since i did mine) they need to be turned a certain way. I dont remember exactly, but the info is somewhere on this site.
