Does he have to spin that prop to start it?

It would have and awesome sound radial engines have a very unique sound like no other, also it would get very hot behind that engine. May not be the most practical bike around but it would always be a good taking point :-)

Didn't Jesse James build a bike with a radial engine some time ago.

Interesting, would love to see it in the flesh. Wouldnt the torque from a north-south engine try to lay it over all the time..?

I think those engines come from SA. There are at least 2 other bikes built with them. Jessee James did a transverse one, and another bloke did an in-line version.
