The fan is thermostatically controlled and the coolant temperature needs to reach the upper level before it will "kick in". Surprisingly as long as the motorcycle is moving forward specially on a fairing type motorcycle the head is dispersed rapidly by the air moving over the radiator fins.
If you were in stop and go traffic with extended idle times then yes the fan will or should kick in.

Both my Goldwings had temperature gauges and were full fairing motorcycles sitting in rush hour traffic I could watch the gauge climb at a traffic light and steadily drop off even at 25mph.

What you may be feeling is the heat rolling out from under the fairing to the rear of the engine which on a hot day and low speeds is enough to feel as if both you and the motorcycle are overheating.

What I've done with my 750 Magna is roll into my drive (on a hot day after being in traffic) leave the ignition on and hit the kill switch, maybe a minute later the fan will kick in for about 40 seconds and shuts off. Just my way of checking.

Another thing on the Fireblade you might not hear the fan over the "normal" engine sound these fans are quiet and that's one reason I did the kill switch shut off so I could hear the fan.

Also the coolant used in a motorcycle is much more efficient then any automotive type and should never be substituted for any automotive type.

Cheers be safe and enjoy your motorcycle

Outside unit will only run for a short amount of time with A/C before the fan stops turning and starts humming, squealing/screeching and the top of the outside unit gets hot.

The bearings are bad in the motor and after the fan runs enough it eventually gets hot, making the bearing screech and the fan locks up. Need to replace motor again. See if it has a warranty. The reason it gets hot is because the fan is what removes the heat from the coil and if the fan isn't running there is nothing to cool it off so to speak.

I have a 99 Pontiac Grand am and first when i bought it i didnt know at first but wires for the cooling fans were hard wired and the car almost caught on fire so we tried to get new wires cause the fans...

if fuses are blowing then this is a indication the a hot wire is grounding out. Now as for the fan,alot of times what happens is that the sensor that tell the fan to kick on goes bad and someone wires them direct" Bad move " make sure there is no wires touching each other and that it is wired correctly and buy new sensor that controls fan. Auto zone will help you out and will also print you out a diagram as to the location and how to install it.....hope this helps and good luck...

You can buy an aftermarket fan kit that will fix that problem. Factory fan is garbage.

Get an aftermarket fan kit and you should be good to go!

Radiater fan will not kick on when hot. Is there a heat sensor that possibly went out. 40 amp fuse is good.

Check for power to the fan when hot. You can check it cold by turning the a/c on. If no power,check the fan relay for power.

it sounds like compressor ain't running check to see if any wires during the move got loose.

2nd if you checked the first, and looks o.k. you have a possibly defective relay/overload.

if you change it and still no cooling well your compressors bad.

hope to be of some help.
