Hey guys, i have a 2000 yz250 that im having trouble with. I took my bike to the track a couple weeks ago and all was well. Its a small track, nothing major. No big jumps. The other day, i wanted to start my bike just to let it run. When i sat on it, it was like sitting on rock. There was no sag in the suspension. It was just stiff and would not move the slightest bit up or down. It seemed as if the rear shock was completley locked up. Any ideas? Thank you for your help!
