In any V twin the pistons act like they are gong up and down in usinon (almost)
If I was going to work out the firing order, I would fire one of the cylinders on each revolution, that way I would have a power stroke every time around.
Sometimes the Harleys sound like they are firing both cylinders in sequence on one revolution and then both cylinders exhaust on the next revolution.
The four stroke V twin would work either way.
Does Harley do it both ways, for instance on different model engines?
Some sound different to me.
I have quite a bit of internal combustion engine experience, but absolutely none with Harley-Davidson.
