Fuel Cooler

Has anyone installed a fuel cooler on these bikes? It seems like we need one as hot as that fuel gets.
I am about to start looking into putting one on and was hoping some one had done it and could tell me the parts I need. I am going to use a radiator type like the one used for the oil cooler.

Thanks

Seems odd. My fuel economy and performance increases at higher ambient temperatures. I always assumed (perhaps incorrectly) that the warmer fuel was nearer the vaporization point and is therefore dispersed more effectively by the injectors.

I thought about doing the same thing...

Take power steering fluid cooler (one with plenty of fins) and run fuel through it. I decided against it because a friend of mine once told me that gasoline is endothermic by nature - meaning it would absorb heat from ambient temperatures as opposed to radiate heat. So essentially you would be warming the fuel up. Although, I am not sure what the point at which the fuel will radiate heat and be cooled by ambient air.

How hot does fuel sitting in a fuel tank get? It mainly sits over the transmission. Exhaust is vented forward and under the bike.

How cool can you get fuel through a radiator?

Will it get down to ambient temp? can it ever go BELOW ambient?

What's the benefit of that degree of temperature drop?

Oil and water get heated in the engine and reach 200+ degrees. I can see where a cooler would work there. Fuel may reach 100? on a hot day. Running through a cooler brings it down to 90-95 deg if you can get it to reach ambient.

If you had a refrigerated coil in the fuel tank...

I've got to call on this, sorry. I know gasoline will increase in volume with temperature, so in theory cooling the fuel could make the engine run slightly richer, but you could get the same effect by adjusting the carbs/injectors. Otherwise the energy density for the gasoline doesn't change with temperature.

I found at least one article that seems to confirm this: a gnat's whisker of improvement for a lot of extra weight.

That is the only intelligent suggestion I have seen on this one!
