Has anyone seen a home built, viable, IC engine? Specifically a single

the world, just viable.
The guys who exhibit at the NAMES show certainly could build a
power plant for a bike. There have been a couple articles in
Home Shop Machinist about an engine with electronically
controlled valves, but the engine is quite a bit bigger than the
typical home shop engine, and ought to be powerful enough to
move a bike. Then, of course, there are the guys with WAYYYY
too much time on their hands who build 1/4-scale Offenhausers,
V-8 boat engines, 18-cyl radials and other exotica. One guy
with a V-8 boat had some videos of his boat doing what had to be
100+ MPH on a lake, but it was all a blur! You could pick up
the entire boat in one hand, I think. 2 years ago, the Sherline
award winner from France had his 1/4-scale Ferrari car there.
The engine sounded quite awesome.
