I just put a new piston in my cr 125 last night and this morning I let it break in and all that but when I was riding it around my yard I went to shift down from 2nd to first and it would not shift. I can press the lever down but it won't click into neutral or 1rst. When I try to move the lever up it won't budge. I'm not sure what the problem is so I hope somebody can help me.
