Fan switch
 
So i bought my bike customized.. and it was a manual switch for the fan, the guy told me to flick it on when the bike get up to around 195-200... I find that quite annoying for some reason and would want to revert back to automatically switch on at those temperatures. Any one can help me with that?

Thanks

The fan behind the radiator should come on manually at 220 F. I your bike gets hitter than this and you dont turn on the fan you run a huge risk of overheating and burning up your engine and should cut off your bike to stop the engine from getting any hotter. If you live in the desert or the south then in the summer your fan will probally come on when your sitting at a stop light, mine does when its around 90-95 outside but once i start riding again the temp goes down

Do you have any idea how he has it wired? Also, normally when this is done it is wired so you are able to turn the fans on manually but also still functions as stock if you don't turn them on when the bike gets to temp. Have you ever let it get up to temp to see if the fan still kicks on?

Exactly. Hopefully he had the sense to just tap into factory wire with a switched ground. Look on left side tank and see if wire is still plugged into thermoswitch. With his homemade switch turned off and key on, unplug wire and touch metal connector to a ground. If fan comes on, it's still wired up to come on automatically.

I have noticed over the years that most people don't have the sense to do things the right way. Prime example is the guy I bought my bike from... All of the wiring he did was just twisted together and he used blue painters tape to wrap the bare ends. There were no butt connectors, taps, etc. I still have no idea how everything worked. I got the bike for so cheap I couldn't pass it up.

Well, in the case of a fan switch...it's actually easier to do it the right way so hopefully that's what he/she did.
