[align=center]How to Install a Fan Switch...[/align]
A fan switch is a good backup in case the thermo switch fails. They don't have a good reputation for reliability, and when it fails, you'll only find out when your engine has become too hot, on a nice hot day, and only when your at the furthest point from where your house is :huh:
The other reason... is if your a lazy cheap fart that can't be bothered to replace it :shy:. The OEM ones are really expensive too, but there are cheap alternatives. Check k916's maintenance thread on the radiator/cooling.
To get the fan on, all that is needed is to ground the control wire for the fan relay. Thats all the thermo switch does.
The thermo switch is located in the bottom left of the radiator. Pull the terminal off the thermo switch, and reconnect it with a male to female pass through... and tap off this for the switch. (or you could just hack into the thermo switch wire
)

Route this wire up to a switch, and then from the switch to a ground point. The ground point can either be in the wiring harness or connected to a convenient point on the chassis. I've choose to mount the switch on the fake ram air duct, and connect the ground to the fairing bolt hole with a wire soldered to a washer. The washer just gets sandwiched on when the fairings are bolted on.

To make things neat, I drilled two small holes in the fan shroud and cable tied the wired in place.

The switch really needs to be mounted on the left hand side of the bike, so it can be turned on/off while riding, without slowing down

I'd recommend either a water proof switch, or a water proof rubber cap screwed on. With ignition on, the fan will now turn on when either the fan switch is on, or the thermo switch turns it on [nod].

Below is a picture of the fan switch. Note, I placed a bullet type connection in there for when I need to remove the duct. You could just unplug it from the bottom, but the bullet connector will pop out in case you forget :blush:, and avoids needing to cut the cable ties.
