I just bought a 03 250ex. A hour after I got home I took it in my yard into the snow. I got stuck and it spun for a second, and I was in second gear. Then the wheels stopped spinning, and I wason the throttle, so I put it in neutrel and upshifted to first gave it some gas and nothing. It revs but no wheel spin. Then it stalled in first and now it won't downshift to neutrel. Anyone know what the problem is? And how hard it would be too fix.
