Air Cooling Questions



Temperature gauge, conditions: Engine idling 11 minutes at 30 C / 86 F air temperature, sunshine.

In stop-and-go traffic or jams, do you switch the engine off if it reaches the last bar before overheating? What is your temperature housekeeping like?

Never idle for more than 5 minutes however last week temperature in Athens 36 C + and Temp. never more that 5 Bars (Including first large bar). And I am surprized to that because the DL was reaching 4 bars very easilly in similar weather conditions .

That is why I am asking, I am not sure what is normal in hot climate. To me it's all normal, but some guys in Germany are trying to explain to me, that mine is getting too hot.

The above was only a test. The engine did run just before, which means it started the idle test at 5 bars (incl. the fat one). 5 bars is what I see usually on the display.

A good reason to select synthetic engine oil...synthetics resist cookoff at elevated temperatures. Also, they maintain viscosity at both high and low temperatures, a critical requirement if you ride in hot climates or cold.

Also, some moly added to the FD and transmission will help maintain gearset lubrication under the same extreme conditions.

A while back I did flip through oil manufacturers data sheets. I found that synthetic engine oils typically have a flash temoerature which is about 40 up to 70 degrees C higher, e.g. 270 C instead of 220 C. In my mindset this can make a big difference especially with air cooled engines.

Check the Noack scores for synthetic vs. regular non-synthetic oil. You'll find that the synthetics do very well in this test. This means that your synthetic oils will not cook off and change viscosity...important in an air cooled engine where oils can reach ~300 F.
