Hi. New to the forum. I hope you can help. According to frame numbers, I have an Li150 Series III (150LI3*693965 * ), but the engine casing number has 125LI *587422*. Furthermore, the cylinder is a 150cc (diameter around 58mm), not 125cc. Can anyone help me as to how a 150cc cylinder could be mounted on a casing stamped 125LI? I presume the motor must have been changed at some time. Cheers, Lloyd
