Just did an oil and fork seal change on a 2003 GSXR1000 left fork because it was leaking before (right one wasn't leaking so I didn't change the seal, just changed the oil). The fork seal on the left was an aftermarket type from previous owner with only one perimeter spring; so I thought, fair enough that's why it was leaking. I changed the seal to a brand new Suzuki OEM seal (double perimeter spring), and this one started leaking too... Do you guys have any idea what could be the problem? To clarify, the fork is not bent, it has not been in an accident.
