Good chatch....thermometers don't sweat so it can not read/detect a wind chill.

BTW, I did just notice that the remnant heat rising from the engine, after the bike is shut down and parked, will affect the reading until the bike is fully cooled to ambient temperture. But just by a few degrees.

 

wind chill affects the gauge by cooling the surrunding plastic and the gauge housing..

how else would you explain a gauge reading 42* after sitting all night in 42* ambient in the garage and 28* after exiting the hwy riding at 65 for 35 minutes, and then 70 after sittign in the sun all day when the ambient was 54 that day

 

It was 42 in your garage and it was 28 outside. Just ambient air temp, not wind chill. By definition, wind chill is what the air temp FEELS LIKE due to the air movement crossing the human body (or words to that affect).

 

ok, i get it, wind chill is heat loss to something thats producing heat, i am standing corrected,

i do however doubt it was 28 that morning, but again, cant argue

but this experiment was a daily thing for me till i pulled the gauge for an oil pressure gauge , i was having the same results everyday, diff numbers obviously, but same fluctuations, some days more than others, but the only thing i can guarantee is it is affected by the sun, mine use to spike up to 80+ in 50*-60* days

thanks frank

 

Here is a biker wind chill chart


https://www.cyclefish.com/blogs/72/768Note: This chart was updated to reflect the latest calculations accepted by the National Weather Service. The formula used to calculate these temperatures is... 35.74 + 0.6215T - 35.75(V0.16) + 0.4275T(V0.16)

where:
V = wind speed (mph)
T = temperature (F)

This formula is only accurate for temperatures of 60° f and below.
