I'm working on a replica of a 1924 airplane originally powered by an
Indian Chief motorcycle engine. I've spent a year or two trying to find
a modern engine that somewhat resembles the Indian, and the best I have
come up with is a Harley-Davidson.

Do you really want your airplane to go "potato-potato-potato..." ? :-)

And on a more serious note, isn't the 45 degree configuration a lousy design
for vibration (or an excellent one, depending on how you look at it ) ?

In the world of high performance hovercraft, motorcycle engines
have been looked at for years. The only situations where they have
been made to work is where they are installed complete with gearbox
and rigged with a complex chain to belt PSRU. Also, they need to be in
an application where full power is rarely needed. After starring at
these harsh realities, most people choose between 2 stroke power or
Kohler reliability. Or for larger craft, a junkyard 4 cylinder car
engine.
