Don't get in a hurry to just take the motor down for leaky gaskets. I've been running my leaking XS for 2-3 weeks now, and every time I ride it, the leaks slow down more. A fresh load of oil does wonders.
I retorqued the head set before I started running it and have done one re-torque. Probably going to do it again next week, even though it was pretty well stabilized this time.
