How often does your radiator fan kick in? - Page 3 - SV650.org

My Thundercat and BlackBird fans come on only when town riding, but on both you can FEEL why it should come on, boiled spuds anyone?

Once moving, a steady 15mph+ cools it all fine.

Mine comes on whenever the engine temp reaches 103C (I think) and goes off at 98C...

Isn't very often - bike normally runs at high 80's - low 90's.

Gladius never heard it come on.triumph rs came on in the time it took to open garage doors.

On my K7 comes on at 100c, normally when just sat at the lights. Generally runs around 87-92c

104 degrees.

I have a sort of related question to engine cooling.

How is it that no matter the air temp, and the speed I ride at / revs I hold for a given speed, the temp will not drop lower than a certain value (about 82)? Is it a simple case of thermodynamic equilibrium, or is there more to it?

Here's another weird one - when doing a constant speed on dual carriageway, I often see my temperature gauge (K5) cycle in a sine-wave between around 79-80 and 86-87. Anyone else noticed this? It's done it since new and seems fine other than that.

yes! i noticed this only the other week after 2 years of having my bike. i assume its always done it. goes from 83-92 and then back down again and up and down and up and down then back down again and up and down and up and down then back down again and up and down and up and down then back down again and up and down and up and down then back down again and up and down and up and down then back down again and up and down and up and down
