Additional Radiator Fan Question and Remedy
I added an additional push radiator fan to work with the stock dual pull fans on my 02 zx12r..
I did this in response to the heat in Vegas 110 degrees and the fan never coming off. I have since pulled the extra fan off to further study the issue.
The issue is the SMALL oil cooler that sits right behind the oil filter. On my zx10 and zx11 the fan almost never came on due to the large volume oil cooler.. If the oil can't cool down makes no difference how much air you can get to go through the radiator.
For me I'm just going to mount a universal oil cooler underneath the radiator and plumb it in..
Before adding another fan I would try a larger oil cooler..

AGREED!! To me, that is not an "Oil" Cooler but an Oil Temp COntroller and maybe a EPA Device to allow the engine to warm up sooner and less emissions.
Remember the thread about Oil Squirters?? People said that the Oil temp ran hotter with 4 Squirters. I said that It may be because more heat is being removed from then engine by the Oil and not gotten rid of by the So Called Oil Cooler. I am adding one to my Bike and the only question is if I am going to have a Thermostat controlled Bypass Oil valve So that the Oil can warm up BEFORE the cooler is in operation
