It also has something to do with the single- vs. dual-pin crank, dunnit?
Nevermind. Pre-cuppa coffee post there.
Blah blah blah blah....
Hello, I am a dual firing coil. I fire both plugs at the same time becaue I'm stupid. I have a sybling who fires each plug independtly and nobody can notice the difference.
It's a combination of the single-pin crank, the angle of the V, and the single carb.
Ducs and Guzzis have a 90 degree V and a carb for each cylinder, and sound very different.
Of course, you're a biker and already knew that. :-P
