Larry I have heard of a KR1 with an 0-200. But as of yet, not in a KR2.
I was hoping to get some information as I have purchased Don Betchem's KR from Red Ewing with the P-51 retract style gear. I'm looking to install an 0-200 just for the fact that I prefer and aircraft engine. I had an 0-200 in my VARI-EZE and it was a dream. Greg S. Martin
