My Aspencade did the same ! The oil came from one of the rubber rings I changed to new fork rings (both sides)and and the problem was solved ! Thats all to do,- the fork rings can,t last for ever especially if you don't from time to time remove dirt and flies from surfaces of theshock absorbers. If you follow clymers advises step by step you can do it easily.
I went out to the bike this morning to check it once again.
Now, I'm wondering if it's coming from the top of the fork. Was hard to tell as the liquid is on the actual fork and the bottom rubber gasket has liquid all over it and, of course, it drips down on to my new caliper!
However, I touched the top of the fork and it may be coming from there.
1. If it's from the top, you think it may bethe rubber gaskets?
2. If it's from the bottom, you think be the plastic o-ring?
3. If it's either, do I have to remove the forks. I've read on the forums that on the Aspy, it can be quite a job to get it back on?
I had this done, made a world of difference to the handling. My forks weren't leaking so my brother only had to take off the caps and we suctioned the old fluid out. Fitted the new springs as per Progressives instructions but they are so strong that it took two of us almost 30 minutes to get the caps on, pushing as hard as we could and cus#rsing and swearing a-plenty.
TheSENSIBLE thing to do is to remove the forks, dismantle, and replace fork seals and dust seals; also at the top of the forks there are two large 'o' rings per fork, (where the air attachment is). Check and change any seals in the anti-dive units.
Then, while all apart, put in your progressives and re-assemble. Once done you can forget about front end leaks for a while, and concentrate on enjoying ride-outs.
One thing to remember though, treat your forks as a matching pair. What one gets, the other should do also (whether it needs it or not).
It isn't too hard of a job. Follow the manual. But it is a lot easier with two people; especially on the re-assembly.
On the following link, the 'O' rings are item no 61. Item no 21, the anti-dive I cannot see too clearly in the pic, you may need to strip to check properly.It's a pity that the parts list (part numbers) are missing, 'cos it also gives a description of the part.
Your seal kit should be fork oil seal and dust seal. If you remove the 'O' rings carefully you may be able to source suitable replacements. Just take one with you to match up.
