for the story about it: http://redoubtreporter.wordpress.com/2010/10/06/bike-takes-flight-%E2%80%94%C2%A0motorcycle-powered-by-airplane-engine/ in the story the bike builder and owner states that there are only 3 radial engine choppers... I guess he hasn't looked at my blog, I've got 3 others posted, Lucky 7 seems to be posted 2wice, before (at SEMA 2009) and after a blue paint job, one chopper at the Pebble Beach Concours, and another I can't locate right now. If you want to see the others, just click the label at the bottom of this post "radial engine"
