EOT meter for OEM oil cooler

[dsinned_imp]

Ulvetanna, your point is well taken and you're absolutely correct. I completely forgot about a front fork compression issue with a fan now attached to the front of the EOC. The CB1100's front suspension travel is spec'd at 4.2" max, but with a fan, there is only ~3.5" of travel allowed before the rear fender touches the fan. Obviously, this presents a potentially serious safety hazard in a panic stopping situation or when riding over a large pothole/rut/bump on the road.

Thanks to Ulvetanna's warning, I no longer can recommend the installation of a fan to the front of the EOC as I have just done in this DIY modification. To do so, would be too risky due to insufficient front suspension travel clearance between the rear of the front fender and the front of the fan.

Unfortunately, the oil supply and return tubes that go to and from the front of the engine are located behind the center region of the EOC. There are also massive down tubes as part of the frame just behind the cooler on either side. These OEM obstructions are in the same area where ideally an auxiliary cooling fan could have been located.

As pointed out by other members here, Honda's designers apparently did not see any need for such a cooling fan, so they did not allow any space to install one.

In all frankness, after all the time invested in this project, I'll probably keep the fan, at least during the Summer riding season, but I will be doing so at my own risk! Fortunately, all the roadways around my area are well maintained, and I never ride off road. Nevertheless, any unforeseen panic stops could potentially damage my fan and EOC.

A big THANK YOU to Ulvetanna for the warning!
