Any of you guys running an F23 on your MiniMax or HiMax?  If so, have you been happy with it so far?  Nice looking opposed 2 stroke.

Running the F23 on my AirBike and have 48 hrs as of 7/5/18.  Has always run great, and even better now that I worked out the exhaust arrangement (heavier gauge mild steel, proper angle for the AirBike, 21" from cylinder to tank front, with some flex pipe for vibration mitigation; looks and sounds a lot better, too).  The motor always starts up right away; even did after sitting thru the 5 months of winter.  I have the prop pitch set for better cruise, so my climb outs are a little weak, but pulling back throttle and cruising at 5000 rpm gives me 65 mph easy.  I use 91 octane with 90:1 mix of BlueMax oil from Recreational Power Engineering (RPE) in Tiffin, OH.  I recommend you checking out the RPE website and talking with Matt Dandar there to get good scoop on the motor.  
Here's some pics.
