Z650 Z750 swaping parts
 

Does anyone know if the Z650 (1980 aircooled four) engine will take parts from the 750... I still want the kickstart but have an excellent 750 crank, rods, pistons, cylinder, head etc. Wonder if I can fit the whole lot into a 650 crankcase/gearbox. Alternatively could I switch the gears/kickstart into the 750?
