Well I was riding and all of a sudden my engine is revving but I'm not going anywhere. I killed the engine and tried turning it back on and it wont start. My clutch arm works and nothing wrong with the cable. So I opened the sprocket assembly and saw that the little dowel pin that holds the sprocket to the clutch axial has been crushed and split into two. Now I don't what to do or where to find this little dowel pin. So if anyone wants to help me out I'll be more thankful.
