I had a friendsomehow ran oversome fishing line and it got tangled in the seal, took it to the dealer, dealer opened it up, removed the line, replaced all the seals and believe it or not, the warranty covered it. just his experience. not sure if all dealers are that way.
A friends bike came new with a seal that was pinched during assembly. His leaked right away though with less than 50 miles on it. Could be the same thing. Whatever it is it should be covered by warranty.
