Interesting debate how a Vulcan V-twin is different than a HD V-twin

[hayes]

The original hd was made from a 10 cylinder plane engine. You get that sound because the crank is still based of ten cylinders. You get fire on 1 then 2 but then you have 8 missing fires. That's the "hesitation" you're hearing.

I was told that by a Harley historian and it made sense. I have no idea if it's true, but I believe it...
