That's brilliant. Just wasted invested a few minutes looking at his channel and some of the other configurations. Some are recognisable, others not so much.

I didn't look but would be good to see the same thing for a 120' crank

The 180 Laverda firing order is shown as 1-2-3,but is that strictly correct?
If the two outer pistons rise and fall together with Bosch or DMC you get a dead spark on one cylinder to give a 1-3-2 firing order,I think,not the 1-2-3 as shown,or is my memory playing tricks and I`m getting this wrong....
Trying to remember the cam inlet/exhaust sequence for 1 and 3 but that`s not helping either.
Or do 1 and 3 spark/ignite at the same time.... Nurse ! I think it`s time for my cocoa...

1 and 3 fire 360 apart. #2 is 180 behind one or the other, as determined by the camshaft. Quick google of a cam photo and you're right it does appear that #2 trails 180deg behind #3. So you'd have 1-3-2 in a 360-180-180 sequence. As pointed out, it's effectively a standard inline-4 with a dead cylinder. Some kind of asymmetry in the firing sequence always tends to deliver interesting sounding engines.
