My drive sprocket is a little worn on me 125M motor and i wanted to replace it since i have it apart. The problem is that the sprocket is discontinued. Its a 14 tooth sprocket and on ebay there are 14 and 15 tooth atc 110 sprockets. They look similar but i can't find any that say they fit the 125. Does anyone know if they'll work or where i can get a 125M sprocket? Thanks
