Following a topic from december last year about engine temperature (http://www.bmwlt.com/forums/showthread.php?t=65333&highlight=engine+temperature+display)
I finally took the time to read temperature(s) using the GS-911. I shut down the engine for no more than a minute after arriving
from work, the engine having normal operating temperature. After I plugged in the GS-911 I took the first reading, then restarted
until the bar graph reached the middle dash. I decided not to let the engine run until the bar graph reached the upper dash, so I
shut it down and monitored the readings and the bar graph until it disappeared at the bottom.
I also noted the cylinder temperature(s). They were about 10°C / 50°F higher than the engine temperature at first, the difference
was reduced to no more than a few degrees when the engine had reached about 65°C / 149°K.
Since all measurements were done while the bike stood still, especially the cylinder temperatures may not be very relevant.

Gaby,

Interesting post and thanks for incluing the thumbnail picture of your results. In respect to the results they are similar with some of my own readings using a digital infrared thermometer where I stopped the engine at various operating temperatures and took readings. I did not take the time to chart out the results like you did I did also measure several different area of engine such as the block, cylinder, cylinder head (intake and exhaust sides), and crankcase. Maybe I will go back and chart them again and write them down just for comparison.

Gaby-

I think that this post is very cool....er....HOT. But just how useful is this info for the average nut, ie, me?

Not very useful, I agree. It was about curiosity to know how the bar graph relates to degrees :eek:
I might add that knowledge by itself is often reason enough for me to explore things :)
