I have an 07 WR 450 with very few hrs on it maybe 50hrs. (not sure) My front left fork seal was leaking pretty bad before I cleaned it and I have lost a good bit of fork oil. My question is can I change the oil in them without changing the seals. I know its really not the best thing to do but Im broke and racing in an enduro Sept.4th. It may be in my head but the front end handles like crap right now.
