The less heat the better.

I honestly can't recall - it's a memory issue I have. Plus, I only glance at the gas gauge and speedo occasionally. Well, okay, I only glance at the number of bars for engine temp

All the speedo is go for is to tell you how much you are speeding.

And that's when it is cooling down in the evening, right?

What is the Max you have ever read on your gauge? Mine never seems to display anything over 117.

It is reported to top out at 122°F. Hotter than that and all you get is ---.

Rod Rides and Wrenches on YouTube does a full 'heat reduction' video with infrared thermometer readings showing the results.
