Hey guys.

Stock '06 R1.

What temp are the cooling fans supposed to come on??

 

[Sharksawyer]

176 F (80 C).

[87CR250R]

220 degrees F.

 

[Blazed_87]

My 05 comes on around 220F

 

[Radical540]

Thanks.
I'm more inclined to believe the 220, than the 176. (176? Where did that come from?) LOL

Uh...the service manual:dundun:

176 doesn't even seem logical. How is it the service manual says 176, and yet two others here have confirmed 220?

What's the disconnect?

Lol... That says the resistance of coolant temp sensor is 0.29-0.35 kOhms at 80C, that has nothing to do with what temp the fans come on. The electrical resistance changes with temperature, which changes voltage, which is converted into a temperature value by the ECM.

Mine come on at 220F as well, '09 R1

Thanks for that clarification.
(I figured 176 sounded absolutely assinine)

 

[r1phil]

most certainly at about 220

 

[Kangaroo]

219 :sing:

Someone had posted a link somewhere to install a manual fan switch to a "green & yellow" wire immediately before the relay.

Just looking for a better explanation as to where to find this wire? (i.e. what (side) needs to be removed to access this wire?)

A few months back, I posted a response to the same question and answered "around 220". The OP said his came on at 176 and I had no reason to not believe him. I will put my dunce hat on now...:dundun:

[Azgoth]

yup 220F is right. My bike is in Centigrade and they came on today a bunch of times at 104?C.

What is the reasoning behind manual fan switches?

 

[Radical540]

MotoGPracing: Thanks! That's exactly what I was looking for....a good pic.

Cheers!

What is the reasoning behind manual fan switches?

Some folks want to be able to manually switch on the fans at a lower temp to keep the bike from reaching its factory set point of 220.

I had a manual fan switch setup awhile back, I'd switch them on around 180-190. It was more of a hassle then it was worth and it did not keep me any cooler.

Personally, if I were to do this again I would not wire in a manual switch but rather wire in a temp switch so that the circuit is completely 'automated'.

I'd use something like this: http://www.partzfinder.com/180_degree_Temperature_Control_Sensor_Switch_p/thg-zfswf.htm

Honda owners do this type of modification as well: http://www.fireblades.org/forums/honda-rc51/64598-lower-temp-fan-switch.html

Where do you install the Zirgo Temp Sensor Fan Switch?? Is there a readily available "port" ?

I have no idea, probably thread it in to a metal sleeve and connect the sleeve between two roubber coolant hoses. I haven't looked this far in to it yet.
