Oil temp is NOT engine temp. Does NOT matter how accurate it is. And I still doubt the accuracy of an oil gauge to accurately measure the temperature that is NEEDED to be read. The engine temp senor is in the back primary side of the front HEAD and has NOTHING to do with oil temps. If a bike is so hot, that one is worried, one needs a tune, anyways.
The Wards fans cools the areas that NEED to be cooled for keeping ping in check and ETIMS out of the picture.
Folks that jump into a thread to post I am an idiot gets the idiot treatment... How do YOU know the accuracy of you fancy oil gauge? You yourself? Not marketing hype? Not what a MFG tells you, how do YOU know it is right? I am questioning what you personally have done to check it?
And... just because your oil gauge reads nothing that matters... I WAS trying to show the OP that he may be worried over nothing... because oil temp gauges ARE notorious for false readings, as compared to actual engine temp, (even doubt EITHER dudes have your perfect gauge.......,) and especially his friend's gauge..

I didn't intend for my response to be taken as a slight to you, I mention oil temps because 90% of riders don't have a cyl head temp gauge to refer to. Yes, Cyl Head Temp is actually the most appropriate measurement to watch, but very few of us has a CH temp gauge.
An oil temp gauge gives you a relative measurement because the hotter the motor is running, the higher your oil temps will go. It's maybe not 100% direct relationship, but it's close enough. If your CH temps are sky high then your oil temps will follow along with that.
Air cooled motors are also OIL COOLED. If the oil temps are sky high then the oil is not going to be able to carry away heat from the parts (because the oil itself is hot as hell).
These issues are best addressed from multiple directions - air/fuel ratio that is not too lean, an oil cooler to bring down oil temps, and FCS fans are currently the best thing going as far as cooling those heads when the bike isn't moving or is going slowly.
As to the JES oil temp gauge, it's very accurate - have tested it in water with a regular thermometer as a gauge.
The H-D digital dipsticks I'd be very suspicious of I agree...

Well just like today in Idaho 98 degrees here today. Due to the temp of engine at idle at a light my ETIMS kicks on. I do have a tuner on and I am not worried about heat. But if the ETIMS is kicking on that means that the setting from MOCO temperature wise was reached and there for automatically turned on. If these fans kept the ETIMS from even turning on would that not be a good thing for the motor?
