The fan is really there to move air across the radiator when you've been sittin there idling for too long which is usually not an issue on a race bike.

+1 Take it off, just something else in a crash to damage your radiator...

if your bike is running 153 degrees on the track then you need to put some tape across the radiator. Use enough tape to get it between 170-180, that is normal temp for max power. 153 is not warm enough. if its a track day bike then i wouldnt buy a fan i know alot of people dont run fans. If there is a delay you will have to turn it off so it doesnt overheat

i would highly recommond water wetter to keep it that cool without a fan, but im sure you already knew that/have it in your coolant.

You can also hook up a small light bulb to the fan wires to let you know when the bike is getting too hot. When the bike tries to turn the fan on the light you wire up will go on as a warning to get racing.

All the prior posts list good reasons to take it off, there's one more : your bike will run cooler at speed without it. On a street bike it's a necessary trade off, not on a race bike. You'll get much more volume through it this way. Also, as someone stated earlier, it's one less thing to go through your radiator in a crash.

On the HRC wiring loom for the RR there is no wiring for the fan so I took mine off. The fan might help cool a road bike sat in traffic but you wouldn't want to be riding flat out with it permanently on. I think when riding quickly air flows through the radiator faster than the fan could achive anyway.

Even with no fan my RR ran too hot on track for best with a standard engine (95 C, 203 F), now the motor has been tuned I'm putting a race radiator on it. If I have to use tape to get it up to temp that will be preferable to it turning the extra power into lots of heat.

Do you mean 95C is too hot, or 95C is the optimum temp?

While it will run without problems at 95C I think optimum temp is a lot lower, low to mid 80's is what I'm hoping for.

Whether this is achieveable now that my motor is tuned a bit is another question.

Depending on the year of your CBR, I'm currently running a sub radiator without fan.

You can kinda see the edge of the bottom radiator in the pic.

As mentioned earlier, and according to Harc-Pro the optimum running temp is 80C or between 70C - 95C

Nice Ride rocketjockey!

I have a question for everybody,
what temperature does the engine start Warping at
from the Heat?

I can't remember what my temps were, but I think it hardly went over 170 farenheit,

I think optimum temp for racing is between 175-185. Mine runs 182 roughly with water and water wetter. I would say that it could cause damage to the engine after 250. The fans usually turn on at 225.
