Test flight is done, checked the temperature of the two back cylinders from underneath, the highest I could find was 160 degrees ferinhigt.
I do have cool flying weather, I'll keep checking when we get to warmer weather next year.
Love the sound of this motor

Have you considered comparing the temperatures of the back cylinders to the front ones?

The front cylinders are guaranteed to be cooler, 30 degrees, it would be in any setup.
