Yeah I’m going to try this tomorrow. I’m currently looking up a diy On here to get the best results.Older bike, same-ish motor; my 998 would get stupid hot in traffic (I've pegged the gauge a few times). Did a few things like getting the coolant system fairly well cleaned out, switching to a metal coolant tank (not an issue on the 999) after mine burst. I finally ended up getting a lower temp thermostat and putting it in and wiring the fans to it to bypass the ECU turn-on point; now the fans come on both at like 180 instead of 212-217. It roasts the hell out of my legs but I no longer see above about 210 on the gauge, even in stopped traffic in the middle of July here in Florida. Wondering if you could wire up a switch to manually turn the fans on; I think with mine coming on a little sooner it keeps the motor from just running away with heat.
