750 SFC Electronica
(Click on the pictures to enlarge)
original Bosch ignition fitted on the SFC Electronica was special for this model.
When these modules came later out
of stock, the factory decided to use the same # 034 ignition box as fitted on the late 1000cc 180° (with Nippo Denso
alternator), Jota 120 and RGSs. This new module has exactly the same performances than the older one, however the timing
is different, meaning that the woodruff key (of the rotor) has to be removed.
The factory advised to machine in the rotor a new groove for the woodruff key, however most of the time the key was simply
removed and the rotor was timed only by tightening its nut, secured by a toothted washer. (Source: Original factory sheet)
