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.

Looks like with an 80 cid Evolution engine I can get ~40 hp at ~3400 rpm
(direct drive) or ~60 hp at ~4500 rpm (PSRU setup).

Has anyone here tried this? Or know of anyone who has done this? I'm
looking for caveats, tips, and techniques. Based on experience, not
opinion. Oh, sorry, I forgot where I was. grin

Based on experience and opinion; Do you know why Harley riders wave to
each other as they pass on the hi-way? Because they never know when
they're going to have to borrow parts from each other so they want to
stay on the good side of every Harley rider they meet. budah bump.

I would say trusting your life to a Harley engine is worse judgement
than trusting your life to a Rotax engine.

You're nothing until you've blasted a can of Delmonte peas with a
Walther P-38... or something like that.
