Well I won't be riding my WR250X for a while... I changed the oil and filter. I didn't find any shavings or metal in the filter or on the bolt. With fresh oil in, I went for a ride to the gas station. The noise was still there while riding, and then it got louder and went *clunk* and then went away. I just figured it was a rock rattling around, so I was like "woohoo, the noise is gone!" So as I am heading home (1.6 mile round trip) I notice that it is very difficult to shift gears. I pull into the driveway and notice that the gear shifter has slack both on the splines and the whole rod moves in and out. Not good. Then I notice oil dripping down slowly. I look on the other side of the motor and see this... So, what all is it going to take to replace the side cover?
