Background on the swap to the 164......
I had a piston pin failure in 2012 with the original 157CSTS on this airframe. Flew it for a couple of months on a DA150. Then I bought a 3W QS150, which woke the beast back up! I scrounged around and found a cylinder set for the 170, classic single spark. I kept things around and covered up. I got ahold of Joe Lewis here in Ohio. Told him what I wanted to do. He said "sounds like fun"! 2 weeks later, I got a text message with a video in it from Joe. Not sure what prop he used, but it rapped up like no tomorrow! I was impressed, to say the least!! But Joe had to machine off .010" or 1mm off the bottom of the cylinders, so that the exhaust port timing would be the same as the 157.
