It occurred to me while mowing the lawn that the motorbike has an extra part that my lawnmower doesn't. On the single cylinder Briggs & Stratton mower engine, the spark plug wire goes directly from the magneto to the spark plug. Whenever the mag makes a revolution, it induces a spark to the plug. Why do these MB kits have a CDI ignition unit? Is it really necessary for a single cylinder engine? Is it because the lawnmower engine is four stroke rather than two?
What's the black box for?

i think this is correct dont quote me but a magnetos spark is regulated by the fly wheel so its only option in incresing spark regulation is by increasing speed of motor by of course adding more fuel - hopefully u understand what i mean -
where as a cdi regulates voltage/ and speed of spark thus working in conjuction with fuel increase to deliver an all over performance improvement--
p.s. "WARNING' it is very very late were i am so i could be just raving
IF I'M WRONG PLEASE SOMEONE CORRECT ME SO I GET IT RITE

Yes, you are raving....
The mower does have a cdi or points/condenser set up. It's just not open to the eye like a bike engine.
The cdi on these bikes doesn't change spark timing, intensity, duration or anything else.
