2nd Fan mod....

[rtvegas]

A few questions..

So, the original fan is still controlled (off and on) via sensor, correct? Also, I'm assuming the manual control is for the new 2nd fan only.. Is this right?

3rd.. How is the 2nd fan wired for power?


Great write up.. Thanks for sharing.. Â*

Yep... just a question if you need a complete second power supply circuit. (can the OE relay carry both fans)

The sensor just supplies a ground to the relay and so a second relay can just be hooked up if the OE relay can not carry the load of both fans.

Seems like you would be better off switching this manually to save the load on the electrical system

Here's the way that i do this mod. Here the link to my post!Second Fan

Theres a different way to do this, on the electrical side, the way that i have done several of them, along with my own bike is you wire the 2 fans together, the oem harness needs to be taped into. The factory wirering is able to handle the as long as you swap the fan fuse from a 10amp to a 15 amp!
Ill post up the rest of my pics later this week! of the fan being installed!

Hey busacruise we need your update on your 2nd fan wiring with photo's, please

There are several different ways to do this. you can use a gixxer fan, busa fan, or an old srad fan. The busa fan will have to be turned upside down to mount. Thats why most people use the gixxer fans....since they mount on the right side anyway. You will have to modify the mounts with any one that you use. You can wire them together or wire the second fan to a manual switch. the fuse will have to be upped to a 15 or 20 amp if you wire them together. You can also install a second temp aensor in the outlet tube of the radiator and hook the second fan to that. This way actually works best because the fan will kick on earlier. You cna also use a temp sensor from a Honda. It makes your original fan kick on earlier.

Do you realy need the second fan? Mine only gets hot at stop and go traffic in the summer and then the fan kicks on and cools it fine I may just get a fan sensor that kicks on at 160 that way in traffic it will cool a little sooner.

Honestly with water wetter or engine ice is a second fan necessary? Are there 10 degree lower thermostats available?
