How come people aren’t warming up to this?
I’d love to have a HD V4! I’ve been contemplating on how to connect them -but alas, I am a physicist, I know more about nanophysics than about mechanicanical stuff

Next to that I love the way thay kept the engine slim, no abotion-legspread like you have with the Boss Hoss, for instance!

AND the ability to fit it in a stock frame (I’m kind of biassed in favour of the FXR)

Too bad the engine will be a tag too expensive to buy, let alone to ship it to Holland

Two stories about the twin Harley, yet when I search The Kneeslider for “Millyard” I get nothing.

It’s real neat that this guy put two Harley engines together side by side, and I certainly don’t want to take anything away from his achievement, but I’m curious why there’s no mention anywhere about Allen Millyard’s various KZs, especially the 2300cc V12.

Why would you run them so they fire at the same time? Wouldn’t that create horrible vibration? I guess if you’ve already got a 45 degree V-twin, vibration isn’t your biggest issue, but it still sounds like a bad idea to me. Didn’t Ducati did the same thing on their V-4 racing motor? Is it because they want all of the vibration to be in one plane only?

WELL I MUST ADMITT, IT DOES LOOK BETTER THEN I THOUGHT. BUT IAM WONDERING WHAT MAINTANCE MUST BE LIKE [ADJUSTING PUSH RODS TIMEING AND SUCH]. ALSO HOW ARE THEY CONNECTED . I DIDNT READ OR SEE THAT.

I think the V-4 design is awesome but it should be 100ci total displacement. The smaller cylinder size would allow the compression ratio to be increased in each cylinder.
