Cooling Fan Issues

[Yedi]

well after 700 miles, my 2017 r-Spec is having issues with the cooling fan. Good thing I have a water temp gauge installed, noticed it hit 220 this weekend, and shut it off right away. Turned the key on and no Fan.

Messed with the key for a while and got the fan to start spinning slowly. than was off and on. Got back home, and the fan sounded normal. Then started this weird off and on crap.

its under warranty so its being brought in to be checked out. Did Yamaha change the fan design at all? I already lengthened the vent tube, and have the JBS Radiator gaurds, and Alba reflash with lower fan turn on.

no change but they will replace it

When the one went out on my Viking I installed the spal fan which moves more air and I eliminated all the factory fan control. I installed an independent temp switch which controls a relay to turn the fan on and a light on that I wired in so I know when my fan is running. Fan now comes on at 192 and goes off at 177. The way the fan works now gives me perfect peace of mind on the trail. I coupled this set up with JBS radiator mud guards and all is great in the cooling department.

Did you replace the OEM sensor in the thermostat housing with a different one? Or did you put it in a downstream hose adapter? And what diameter fan did you use? OEM plastic shroud? I think I heard mine growling yesterday for the first time, over 1200 miles so thinking its time for proactive preventative maintenance.

I just added a temp switch in the radiator hose with an adapter that I built. As for the fan I comes with a new metal shroud from Universal Parts Incorprated. I got the temp switch from them as well. The fan comes with factory connector. I cut the pigtail off where the fan plugs into the chassis and I used it to wire up my on control circuit which is much more simplistic than the module controlled factory circuitry.
