My Twin Cooled M8 runs cooler than my '13 Ultra did...
Taken today... while Auto Tuning my FP3, Catalytic Converter in place, right leg does fine.

I am measuring the temp with the HD digital oil cap with built in temp and oil level readout. Typically these readings are in about 68F weather and moderate stop and go and freeway riding. Not parade type riding to be sure. Typical around-town riding.

Overall, it's a cooler motor than my TC. However, the right side still hearts my thigh.

Right on. I thought you were talking about engine temp.
