when it is faulty, an error message should appear?
My bike run too cold, but sometimes the temperature rises up 100ºc
I'm in doubt between thermostat or water temperature sensor

Bleed the coolant first. I had the behavior where the bike would run normally most of the time, but then occasionally jump to 250F. This was after a small low side.
I bled the coolant, two big bubbles came out, and that was that. Problem solved.

"rises up 100c"
do you mean rises up to 100c, or rises by 100c to a higher number? huge difference between the two.

It all started after a small low side in garage!
my bike takes a long time to heat! COLD COLD COLD for long time after start up!
and the temperature does not rise!
60º~70º in brazilian summer..
I decided cover a half intake of radiator..
ok! great temperature, 80~90º.. suddenly the temperature rise up 100ºand poured fluid in the exhaust...
it knocked me down on track!

i apologize, but the language barrier is making it hard for me to understand you.
am i correct in understanding that after a minor tip-over in the garage, you had a boilover that poured coolant onto the outside of the exhaust?
i want to confirm that you did not have radiator fluid appear on the inside of your exhaust.
a malfunctioning temp sensor wouldn't cause a boilover. a tip-over could trap air in your radiators and cause a bad burp of air and fluid.
prolonged warm-up is a classic symptom of a thermostat that is stuck open. i would not block the radiator intake.
it sounds like you need to verify that the thermostat is working, and bleed the air out of the radiator. the good news is that if you follow the service manual procedure for bleeding air out of the radiator, you can watch the coolant circulate in the radiator and you will see the circulation pattern change when the thermostat opens.

I have already a new thermostat!
but still in doubt about the sensor
no! I dont have fluid inside my exhaust
leakage outside! this white spot
leaked by this hose:

Don't worry. Your english is very good. It is hard to discuss technical problems, which require exact language.
Did you replace the thermostat, after the lowside crash at the trackday?
Did you bleed the air after replacing the thermostat?
Are you still having boilover problems after the thermostat and bleeding?
If the boilover problems were fixed by the thermostat and bleeding, and you still see strange temperatures, then I would look at the temp sensor.
Here is some information from the service manual:
Engine Running Hot, consider:
1. Stuck thermostat
2. Blocked pipes, hoses, passages
3. Bad cooling fan
4. Bad water pump
5. Air in radiator
6. Air i hoses, pipes, passages.
7. Defective pressure cap
8. Defective engine coolant sensor
Engine Running Cold:
1. Stuck thermostat
2. Bad coolant sensor
3. Bad fans
1. Damaged pressure cap gasket
2. Bad water pump
3. Bad O-rings in water pump
4. Leaky hose or connection

Have you bled the coolant?
Seriously, I had the EXACT same problem after a low side.

Zecca - Like my esteemed colleagues have said - you got air in your cooling system. Put the bike on stands, start it and run for a while with you radiator cap off. Make sure bike is warmed up and water is flowing through entire system.
Nice track, BTW - Zecca likes to go fast. Get some case protectors, too - they work real nice when you go pavement surfing...

Hijack: I am anxiously waiting for the UPS guy to deliver my carbon bits today. It's 5:30 -- Where is he?!?!?

Stirz007 I tried it! when it gets warm, fluid leaks by the cap! is this it?
the bike is completely disassembled! the radiators are off the bike!
when I finish the repair on frame and subframe I will replace the thermostat and and add water! only water! without the fu**ing anti freeze fluid!this is a soap!
this case protectors?
I should have bought!

was veeeery fast! suddenly my ass was scratch the asphalt!!!

From my lowside last May - note hole behind vent in side bodywork - I managed to grind the case protector a bit, but other than wrecking almost all the bodywork, there was no engine case damage.
Also note mount for camera on the pod - the Contour took the hit (it got ground down too, but still works!)

that could the problem. a faulty cap / gasket could easily cause a fluid leak.
