I got my X back together over the weekend and then lent it to my dad. When he returned there was fork oil everywhere. It was coming from the left fork dust cap. I pulled the dust cap up and there was oil laying underneith it. I cleaned it all off and looked at the seal (which was brand new) and it looked fine. Snap ring was in place. Looked like nothing was wrong. I installed chrome lower forks. I put 15.5 ounces of oil in each fork and pumped them to remove any air. I did not measure the level from the top. I have no idea how much leaked out. What could have happened? Did I overfill it?
