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 and put it on? Are the studs the same on the 140 and the 125? And last but not least, can i put the 125 cylinder head on the 140?
is it even poosibel to make it work? Or i am just dreami'n?
