cbr929 lower temperature fan switch

When searching the forum. I found this thread
https://www.fireblades.org/forums/ho...an-switch.html

I was wondering if anybody had done the same for a cbr929 and found a lower temp fan switch, either from a a maker or from another vehicle that fits the 929?. And if so since mine is bad i would replace it with the lower temp fan switch.

Re: cbr929 lower temperature fan switch

not heard of it but make sense - over 100c seems too high for me and would rather it came on earlier tbh. keep us posted if you find one

Re: cbr929 lower temperature fan switch

You can fit a manual switch easy enough?

Re: cbr929 lower temperature fan switch

you can but looks naff and you'd have to be watching the temp all the time - I like the idea of having the fan simply come on earlier automatically

Re: cbr929 lower temperature fan switch

Coolant boils at 106C? Fan comes on at 103C? I think a car sensor would be needed for a lower trigger point, instead have you looked at waterless coolants for bikes? The boiling point is way way higher at 180C;

PowerSports R is the coolant of choice for many professional racing teams and performance bike specialists. For racing teams such as Honda, no other coolant offers the performance of Evans waterless coolants.

knowing myself. It's not really a good idea for me. I wouldn't notice it was overheated until it was overheated

I am running a coolant called Engine Ice already, which I think is a waterless coolant, but dont remember.

Re: cbr929 lower temperature fan switch

Does anyone by chance know the thread pitch of the cbr929 fan switch? I am assuming 16 x 1.5, but im not sure

I'm not sure the actual boiling point of the coolant is the issue, more the running temperature of the engine. Low to mid 80c is good for engine and power, too hot and you loose power and don't forget the oil is cooled via an interchange with the coolant.

err - race teams don't use antifreeze or additives, just distilled water - any loss on the track from a leak or spill is a bitch for the marshals to clean up properly so no additives are used in most racing. I know a few team guys in British Superbikes to know this is fact. Perhaps motgp teams have something special but nothing is used in most domestic championship racing in the UK at least.

Re: cbr929 lower temperature fan switch

UPDATE: I fitted a fan switch from a 1983 Nissan pulsar. It works perfectly. Comes on at 195 and turns off at 185.

https://www.carid.com/standard/inter...5#applications

It is supposed to come on at 195 and turn off at 185. But not sure if it just my bike (maybe my coolant temp sensor is off) but mine comes on at 192 and turns off at 180. Not sure if I'm gonna keep it or just go back to a new stock switch because i guess that it would always be in in light to light traffic/streets and only turn off on freeway, which I'm not sure is good or not.

I did find a lower temp switch. It came from a 1983 Nissan Pulsar. It has the same threads and comes on at 195 and turns off at 185.

I am running the same switch in my 2000 with good results.
