I was looking at that on the show room floor before I bought mine. That fan looks really small for the size of the radiator, especially with no shroud. There should be something out there small enough to fit below. Not sure what the temp. switch capacity is, if it will handle another fan or not but it could be relayed real easy. And with the stator output on this thing, running it would be no problem. I am still thinking strongly about adding another small light to tell me when the fan is on.

 

Really what you want is the coolant temperature guage! I want a full guage cluster with a speedo, tach, temperature guage, fuel guage. For me, it's pretty obvious when the fan is on - either you can hear it or feel it!

 

Yes it would be nice to have some gauges instead of idiot lights. Looks like there was some intention for that in the design. Westberg Mfg. makes all kinds of gauge set ups. On there current catalog, page 30, they show some Harley 4 inch gauges with four different read outs. I dont see any with a speedometer or tach though. Their web page is www.westach.com if anyones interested, they have a free catalog. They would probably make something up special if there was enough demand for it. They don't list any prices on this particular page so they may be priced pretty high.
