I'm having issues with my bike getting hot.  The only temp gauge I have is the mounted in the oil fill and I'm seeing 100 *C even at 25 mph.  I bought a powercommander to take care of a lean pop during engine braking and that has helped with the overheating a bit.

Has anybody found a fan that fits behind the oil cooler and won't explode at 75+ mph?  Any other ideas?

100 degree C is pretty normal. you shouldnt worry about it until you hit 330F, thats ~150C. im usually running at 220-30 until the summer time, then its 270-310F

I try to keep it as cool as I can by avoiding city riding.  I find that my stainless steel pipes haven't browned up on me as much since I have been doing this.  The max my bike has been this season is 240F

The thing is that the temperature I'm seeing is the temp of the inside the crankcase not the actual oil temp, I'm thinking that there is a 15-20 *F delta between the oil and the air.

When I see temperatures over 80 *C I notice big difference in how the engine behaves.  I would like to keep it in the sweet spot if possible.

Look at your plugs, this is a better indicator. Remove the plug after a ride (carefull they
ll be hot) and see what they look like, then compare to this chart.

Just advice to avoid and rule out the lean situation, not trying to scare you. Quality oils and fluids also help reduce friction, which helps keep things cooler too. So perhaps investing in top-end oil might be worth it???
100'c isn't uncommon either and my bike is air cooled. - Chris

Your temperature is well within normal range.  Oil needs to be at least 82⁰ C to burn off contaminants.  On newer Monsters with oil temperature readouts too hot is 170⁰ C. 

I have the same oil temperature gauge on my bike.  It is reasonably accurate.

The plugs look good, and I already use Amsoil.  I have been thinking about switching from 20W-50 to 10W-40, the lower viscosity should give me a lower oil pressure and therefore should generate less heat.
