Fred, et al:

I recently became interested in motorcycles.  I have a Honda VTX 1800 - a 2
cylinder, liquid cooled, sequential electronic fuel injection, electronic
computer controlled ignition, medium compression, 120 lb ft torque, 106 shaft
HP with peak power at 5200 rpm engine utilizing 87 Octane no lead.  It has 4
inch pistons with a 4.5 inch stroke (similar to my Lyc 320).  There are other
engines with electronically controlled valves.  

The liquid-cooled engine problem can be solved, but by whom?  Honda, Toyota,
Rotax, Engineair?   When?  With an ever declining interest in aviation,
therefore aviation piston engines, why?  Maybe third world country's need for
GA will save us all.
