Waste of money!!!

 

Our thermostat starts to open at 80 to 84 degrees Celsius and it's fully open at 95.
So you are always just a few more degrees away from the ventilator starting.
You could replace the thermostat with another that opens at a lower temperature or just drill a hole in the one that's in your bike.
I think it already has one, just make it a little bit bigger

 

I have been thinking exactly the same about the thermostat
Just second thought was about oil cooler
Thanks

 

How hot is the bike? High temps in stop n go traffic should and will cycle the fans . As long as the temp don’t go into the red you will be fine. These bikes are designed with slower speeds and higher revs (trails and off-road riding) so they are very good at not overheating, as are all dual class liquid cooled bikes.

 

Temperature is ok
Just on hot days (over 27 degrees ambient temperature ) the fans running and take long time to stop that’s why I’ve been thinking that oil cooler could helps

 

I imagine if the engineers thought it needed one..............

 

I'm afraid it's not that simple.. Engineers have to think about many things...

To reduce emissions (like unburnt hydrocarbons, carbon monoxide, and nitrogen oxides), engines are designed to run hotter.

A hotter combustion temperature improves combustion efficiency, meaning fuel burns more completely and produces fewer pollutants.

However higher temperatures stress engine components: metal expands, oil breaks down faster, gaskets and seals wear out quicker.

Over time, that can reduce engine life if not managed carefully (e.g., through better materials, better cooling systems, or advanced lubricants).

But they also have to make a profit and at the same time keep the price low.

So it could definitely needed but costs, complexity of production would not allow it.

 

a weight/cost issue, no to mention something not really needed and something to get possibly destroyed off road. Along with having to slightly increase the oil amount. I can see why Honda wouldn’t go with one.

 

I'd rather install additional and manual switchable radiator fan, like enduro guys do

 

Yes, fans turning on at a lower temp - 10° F sooner can help. It’s an option in tuning / flashing software like Woolich along with usually running a bit cooler due to proper fueling.

When parked, I wouldn’t leave my bike running when the fans are on just to let it run until the fans turn off. Rather just shut it off and stop the heat soaking from engine running.

 

Hi,
agree with above. A liquid cooled engine doesn't need to run idle and stopped to cool off, only if turbo charged to cool down the turbo charger.
Running the bike not moving will dramatically increase the time to cool down the engine and to stop the fans. On my old XRV, it was very difficult to even start the fans, must have been a very hot day and a heavy stop-start traffic. I would turn off the engine using the switch not the key and let the fans run with engine off. You can try, CRF will probably do the same. Battery should handle the fans running for a minute without the engine.
Or you can ride for a while to stop the fans working before stopping..
