I posted this question elsewhere, but it was kind of off topic and buried in a thread. I'm starting to see some fork oil leaking from one of my seals. Is it really common to blow them? Seems most folks are just replacing at the first sign of leakage. What are the signs of damage? Stretching? Tear? I'm going to order a seal mate and try to clean them first. Just wondering what I'm looking for before I tear it apart. Thanks.
