Just wondering if anyone else has experienced excessive engine heat? I have only 3 hours on the bike, was riding single and two track trails through moderately deep sand and at varying speeds. The fan was on far too often for my liking and, while not spilling coolant, I believe it was close. I would love some feedback on this subject. Thanks.

Isn't there a switch to change the ecu and FI mapping?
Most new bikes come running lean from the factory to lower emissions.
I think there is a thread here about it too.

Depending on how fast you were going & the gearing it's possible that it was running a little hot. The bike is new also, so let it break in a bit. You don't want to lug it so much, just a tanks worth of hot & cold cycles. When it's all broken in get rid of the thermostat and the stock coolant. I run even's coolant which has a higher boiling point.

Your exc, if its bonestock from the dealer and untouched, is definitely running lean. Advance you tps and adjust your idle knob. if its possible have the dealer remap your ecu to an EU unrestricted map. Lastly, youll want to remove the smog/emissions junk from your bike. excessive heat, stalling, popping on decel, etc are all inherent problems with 2012+ EXC models.
do some searching and reading on the net and youll see more information on what i have mentioned.
also, youll eventually need to remove that thermo because most eventually fail and/or melt(according to my local techs) which will leave you stranded. as jimmy said, evans coolant is the way to go.

That sounds like solid advice. Is a manchild like a shemale? Jus kidding! Ha ha

I got the hose kit from Blais Racing that eliminates the thermostat and went to Evans coolant too, but where I ride it has been cool anyway so overheating is not an issue. Also either Blais or Slavens sells a simple washer that takes the place of the thermostat in the housing-a cheap way to remove the thermostat.
This sounds like solid advice. In talking to the dealer tech after he contacted KTM, their response was to change the coolant, lower the thermostat temp range, but recommended not to run without the thermostat to retain designed heat ranges. The tech also suggested the possibility of replacing the radiators with a more efficient unit. I have contacted Eric at Mylers and have a pair of radiators on the way. I intend to put on some easy fire road hours cycling heat and modulating throttle to let the bike settle in a bit and I will then switch out the radiators.
