I just got a 2006 cbr600rr and i rode it for the first time the other day, when riding slow or idiling the engine temp went all the way up and started blinking and the temp light came on. I check the coolant and it was low so i added more and changed the oil.

I let it idle in the garage and the temp went way high again, like 230f. I shut the bike off. Any idea of why this would happen or what may cause this.

If no one has any ideas Ill have to bring it to the shop and have it checked out.

any help would be appreciated

 

Is the cooling fan coming on?? 230 while sitting stopped idling is normal as long as it doesn't go above that, but the cooling fan should have already kicked on by that point and be cooling it down.

If the cooling fan is running and you have no air in the system, then most likely sticking thermostat. No visible coolant leaks anywhere??

 

exactly... also i posted reponse in other thread

 

The fan is kicking on, there are no visable coolant leaks anywhere. The motor is clean as can be, only 1034miles on it. the fan kicks on but it dosent really seem to cool it down fast when it reaches those temps.

Ill have to take it out and see how the temp is.

 

your fine. what is the outside temp? dont worry about it these engines make alot of heat and if it's hot outside it's even worse

 

I've got my motor in the red zone a few times while sitting in traffic. Its still here.

 

It was only like 50f out the other day. It was by all means a cool riding day and the temp stayed around 234 while riding on the highway. One stop light put it into the red and on the way home samething. I had to stop at a gas station and shut it down (well I had to get gas too) and then was able to ride it home but the temp stayed very high.

I have since added coolant and let it idle in the garage and the temp was high like 230+ and the fan does kick on at 219. It seames to go up then down a little but right back up. I had a 2003 r6 last and I cant recall the temp every getting that high, even on 100 degree day in traffic Which is why im a little concerned

 

If it's at 234 while you're riding, it's definitely running too hot. Only time it should be that high is when sitting stopped. I'll bet your thermostat is sticking

 

Flush the cooling system completely. Make sure their isn't any problems with the point at which the fan sensor (or if it's run off the ecu) connects. I'm not sure if that still runs into the top of the out diator or not. If so, clean the contacts on the connector with dielectric grease or a pencil eraser. Run some redline water wetter or Engine ice in it. These really do work great. Make sure all the air bubbles are out of the system. Run a pressure test on it to see if everything is within specs. Change the oil to a slightly lesser weight so the oil pickup/pump flows it easier.

These are all the things I could shoot out just quickly off the top of my head.

 

Did you put fresh coolant in the resovoir or in the radiator itself? If all coolant levels are fine and you're still overheating you've got;

air in cooling system
thermostat stuck closed
faulty water pump

Any one of the 3. I believe the psi for the cooling system is something like 6. It should hold that pressure for I think 3-5 seconds. Don't over-pressurize!

After checking for air, test the thermostat. Suspend it in a pan of water and heat it on a stove. Check the manual for the specs, but it should click open at a specified temp.

If all those check fine, replace your water pump, refill the coolant and ride that bitch!
