    Convert Lifan 125 to 140cc

    Hey, i have that question that I have two lifan 125cc engines and both engine numbers are 1P54FMI. I want to put a 140cc cylinder on one of them if it is possible. Are the strokes the same on the 125 and on the 140 or it is different? If different is it possible to lathe to size the 140 cylinder...
