KR> KR-1 Corvair...

[tinyauto at aol.com]

I thought a neat engine for the KR would be the Yamaha Genesis (Vector 
snowmobile) engine.  120-150 HP in a tiny 4 stroke package.  There is even a 
commercial conversion adapter being made for it now that adapts the Rotax 
gearbox to the engine. I think the running weight is somewhere around 160 lbs.  
Not sure if that includes radiator.
