Your jetting has a whole lot to do with it, because we don't hear much about 40X's over heating,especially with the too lean stock jetting replaced.
Try this,and follow the directions in the box:

I run water-wetter with the factory Honda coolant. Never put tap water in your bike, will corrode the aluminum. Never have overheat issues, even in Mojave desert. I agree with other guys, check jetting and also make sure ignition is running correct. If your timing is off it could easily overheat engine or cause detonation! I know this sounds basic but check your oil frequently. Even new hondas will burn some oil, especially at high rpms. Remember your engine holds less then a quart! So if you burn even a ounce it's like being a quart low in a V8. Good luck Bro.

On my 450x I use engine ice and I changed my radiator cap to a SRC High-Pressure Radiator Cap 1.6. Ever since I made these changes I don't have any overheating ssues.

I think he was making the point that here in California our bikes are sooooo lean to pass emission standards that jetting could be an issue.

A lean bike runs signifigantly hotter than a properly jetted one.
