Just a little thing, when you'll install the FOC, don't panic if you're not able to close the transmission case tight, becaus on the manual they give with the FOC, when it's time to install the gear on the output shaft, the picture not indicate the proper way to install the gear over the pin. To the place of slide the gear from the left side thru the gear, you must slide it from teh right side of the shaft.
Maybe you don't understand right now but when you'll have the picture in front of you, you'll understand.
