K2543 ¿is it usable in a single cylinder bike four stroke?

That is my cuestion, as i want put it (K2543) in the (1972) Sanglas 400E and (1977) Sanglas 500S, bot are very similar bikes and very populars in Spain.
Petrol single cylinder four stroke, 12 volts points and condenser.

Many thanks. Antonio from Spain

If the bike has a negative ground, then it should be possible.
