HuH? Harleys were built that way in the 19 naughts! This was done to
save weight. Unlike you the engineers back then knew that you could
provide two crankpins and have one cylinder fire every 360 degrees at
what ever angle they chose. The 45 degree angle is simply to get the
engine into a small space as possible in the frame.

I should have known that, after all I just got finished putting
together my Ford V-6 which is a 90 degree bank angle V-6. It has
displaced crankpins to allow for even firing.
