Finally, after work and a bout of sciatica intevened, I'm about ready to get some miles in on the SF2, before a thumb operation in November.
SF2 Owners, Help, Please?

Great! Thumbs up for the thumb!
Which thumb? You may not be on the button for the Fiamm horns....boys loud button.... Be interesting to read of your perspective Sock, only ever ridden triples, to then scale the heights of a twin, different..... rode many variants of customers twins, a grin here. Will say the "walkies" at idle while amusing at first, had me tethering the odd one to the nearest post, j.

The left, Jon. It's been bone on bone for a couple of years, so I'm hoping they can restore it to its former glory or, at least, let me pick up my drink without wincing.
Re: the comparison, I've probably had the Triple too long to be fair to the Twin. The vibes are way more than the Triple can produce.
Access for maintenace seems convoluted but, perhaps, it's just a new set of idiosycrasies that I need to get used to.
Performance is gentle by comparison, but then it would be. Like Meatloaf sang:
Many the similar riding observance as you noted. At least you have the right thumb to get it started, cannot have bad luck all your life. Sympathetic mode for loss of inter joint protection, here. Knee for me... not self healing.
One twin i rode vibed that bad i lost visual focus into a corner, ended up in a paddock, though not seeing was in conjunction with 18psi in the front tyre.... loss of on tap urge another notable, motor and myself. Then i suppose my dotage may see that reverse. j.

Nice piece—I too just with the help from this site my first Laverda a 74 750 sf2—looks like your two questions collected enough response—just wanted to share my success with install of British twin electronic ignition—-then when digging into the tech forum this site saw that some gent beat me to it
Option for losing fussy points
Cheers
Electronic ignition has two tasks, provide a healthy spark energy from cold crank start to upper rpm, next is to "advance" the ignition for a best motor/carby performance with safe margin. Adapting an electronic ignition from another motor brand may or may not bring best performance for motor and rider. Long ago and in a land far from the USA, some lesser thans proffered Boyer Bransden ignition for the Laverda engines, the originator had special crank timed product produced as opposed to the plentiful look alike ignition modules, derived for cam timed motors.
Poor performance was assured of this hijack technique, and Phil got the blame for what others thought was a quick earner. The twins are fairly tolerant of ignition timing, sort of. Protection of the motor is paramount, a cam timed ignition on a crank pickup/encoder will ensure a motor never in danger of over advancement, maybe the 30hp will be the clue.
Adapt items as we need, to keep the very old now, Laverda in some sort of road reliability and safety, engineering also needs close attention. j.

As mentioned on here previously, my first 'points replacement' exercise on an SF was to machine a little off the Bosch advance unit points lobe, Loctite on an induction trigger and plate from a late 70s GS Suzuki, and wire it to the little ND CDI(?) electronic box from same Suzuki. It worked faultlessly for several decades and has done to at least two other SFs around that time - super reliable.
Only changed to Ignitech because it gives far greater options for adjustment and setup and, I expect, a more accurate spark at all rpm. No idea about the Triumph type options like Lucas Rita but i liked my setup a lot. Still have it in my box of bits as a long-distance travelling spare! Don't think I ever saw a Suzuki broken down with a buggered electronic ignition system

A mate with a HD fitted a Jo Hunt magneto, which shit itself on shutdown. He bought another (albeit second hand) and it too shit itself on … shutdown.
His emails to the manufacturer brought no luck, or replies for that matter.
We discussed the failures at length, all it took was a flat washer added to space out the spinning brass thingies inside, which crashed into each other as they lost momentum.
Point (pardon pun) being, even the simplest ignition systems can be a pain in the arse.
