Cooling mods

So I searched and read, search some more and read some more....

I use my sp1 for teaching motorcycle refresher trading to us soldiers in conjunction with MSF. Bike is off and on, slow maneuvering, and until we do the check ride at the end of the day my bike sits on hot asphalt quite a bit. It never goes below 200 degrees.

I want to do a manual switch in conjunction with a 190 sensor, reverse the fan direction and go to straight water.
I assume this will help quite a bit. Am I correct?

Havent read anything about the 'straight water'...but the Nissan sensor may be all you need.

A switch will help, a lower temp sensor will help some too, but she'll still get hot - over 200.
I have yet to do the SPAL fan mod, but from all the material I've read about it, that's the most effective. Especially when used with a manual switch.
I've used the lower temp switch on my SP1. Didn't help much when the outside temps exceed 90F degrees or so.

I don't know about that. I've asked a past poster about it, he said it's entirely do-able.
But others argue it's not, and it's still too anemic. It won't increase the cfm's, and you have to know how to reverse the direction of the fan motor AND reverse the blades? I don't really know, didn't sound like it was worth the effort to me...

OK. I was noticing today that I was running 200-210 while running 65 mph in 6th at 4000 Rpms. I called mike at kyle and asked about that high of a temp. He suggested water wetter and to check my thermostat. I though about trying to run the radiators in series (?) Instead of the way they are now.

With 2 spal fans running off of a manual switch, the temp will basically drop to the thermostat opening temperature (~178 degrees) and stay there. I have not tested this during the worst of Summer (that is still to come), but so far that has been the case.

go with water wetter. Straight water over time can potentially start corrosion.

96 with 104 heat index. I put in the switch and flushed the whole system. Refilled with straight water because I had to order water wetter. Nobody has it here. Temps were great. Stayed right around the 185-190 range in dense traffic and high speeds of the interstate.
