    Same here. I went with the switch above from KTM Twins. It was the cheapest I could find......

    Well written advice.

    Too many people that think they have to re-engineer what the engineers did.

    Maybe you two should first own a 690. Just saying...

    Had mine with the stock switch for 5 years and 27K miles. Hasn't burnt up yet, much less ever overheated.

    My stock 690 SMC runs hot, no question about it. I am looking to switch the thermostat and pipe, but doing the 2nd/3rd gear mod did miracles for my bike. I was very skeptical and didn't expect anything of it. But my bike runs 1-2 bars cooler in traffic compared to before, only had the fan kick on twice going up on the same trails as last weekend when it was almost always on. Big plus also, not stalling at stop lights any more, not even once. Smoothed out the fueling as well. I am judging all this based on the same conditions and riding in two back to back weekend trips of 300-375 miles each. The only difference was that I did the mod. I actually like the bike now :clap

    Is it the sensor that switches the fan on and off, or doe's the sensor send a resistance message to the computer and the computer turn the fan on and off. I fooled the computer in my Nissan p/u to richen the mixture by putting a resistor in series with the temp sensor. I eventually put a variable resister (potentiometer) in series and it was tunable from the driver's seat. The resistance of the sensor loop can be eaisily changed by putting a resistor either in series or parallel. If you don't know what this means ask a Ham radio operator (KJ4AMH here) This might be a cheap and simple way to get the fan to come on at the temperature you want it to.

    The fan temp sensor is located in the right backside of the radiator.

    It simply completes the ground to the Electric Radiator Cooling Fan When it's temp is reached.

    The computer does NOT turn the fan on :nono

    Has anybody installed a manual switch for the fan, like I did on my old DRZ400. I do not have a big problem with my 690 getting hot, but since I live in Fl, i'm thinking on installing one.

    Hi,

    Almost ready to get to Tunisia,
    just wanted to replace the stock sensor with the one frm RallyRaid
    (88 deg.) but talking with my KTM dealer told me this could cause
    a fan high workload , with the risk of breaks...

    Now I'm confused....donno what to do... ;)

    Cheers

    I did a few years back when my bike over heated on a ride. I have had no problems with it overheating now, just turn it on when I am trail riding. At some point my thermostat did die but didn't replace it till a few weeks ago. Ran it for a year or more just turning the fan on manually.

    I have the Rally Raid switch. The fan comes on sooner and has the bike running one bar cooler. Would you rather work the fan more with the possibility of having to replace the fan at some point in the future or keep the stock switch and replace the motor at some point in the future? I live on the Gulf Coast so heat is definitely an issue. Also use Engine Ice or similar for coolant. It helps.:deal
