Just a random thought. Fan is Ecu controlled, so ktm knowing about all the head gasket issues should do an update on the PCM to lower the temp at which the fan comes on. Seems like a super simple fix. Drop the fan temp on time to 90 deg or something. Maybe that would aid in the longevity of these engines. I'm guessing it's a simple switch in the code to swap out to a lower number. Maybe chad wells can step in on this and comment
