Poor old girl has been neglected lately .
New wheel bearings front and rear , new brake discs front and rear , new tyres ( Perelli Diablo Rosso 2 )
New plugs also .
Rode like dream. Bloody hot day , forgot how much heat this old girl pushes all over the rider.
Of course I was thrashing the hell out of her .

I'll take a stab at this: Since 12V isn't nearly enough to generate an arc on a spark plug, we need to condense the voltage way up to get a spark. That's what the ignition system is responsible for
Back in the day, before we had boatloads of cheap electronics in everything, they had to use a mechanical system to generate ignition, generally a points and condensor arrangement. I've got one on my '79. Purely mechanical and very simple but higher maintenance since those things all wear out over time
Modern engines use electronic ignition, which does the same job, but using electronics instead of mechanical contacts. An example is the simple digital system that the Hurricane came with, where the pulse generators send signals to the spark unit, which passes those signals on to the two ignition coils responsible for stepping that voltage way up to give us our spark
You can spot either of these systems by the thick wires leading to the spark plugs. Those thick wires are necessary because of all the extra volts coming off the distributor/ignition coils, but they are also failure prone, and often come apart in your hand when you're trying to check the plugs. Annoying and expensive to replace.
Stick coils connect directly to the spark plugs and instead of thick leads you just have a pair of standard low-voltage wires plugged into each stick. They do the job of the ignition coil, but in a much smaller package. More consistent spark, and arguably more reliable. Definitely neater and more convenient. Also super easy to troubleshoot. Saves a few grams too, if you're the type to keep track
I did the mod for about the cost of a set of wires and it works great. I don't expect it to perform better, but I figure it'll save trouble in the long-term
