The tempreture in my cbr 400rr get high every time i start ride my bike it come over the meddel i ride my bike in a small city it start come high after 5 minutes i start riding bike i put in the redeter...
Is your fan kicking on when your bike starts to get hot?
On my cbr the fan would kick on at 215 degrees. Even sitting in traffic on a 90 degree day my bike would only get up to 220 at most.
If your fan is kicking on when its suppose to and you have your radiator filled up full then I would check your thermostat.
The thermostat is an object that opens up when your engine reaches a temperature of around 180 degrees and lets antifreeze run through your engine to keep it cool. If the thermostat isn't opening up then the antifreeze isn't circulating through your engine, its just sitting inside your radiator. And that's not what you want.
You can remove the thermostat from your bike and put it in a pan of water and heat the water up with a candy thermometer in the water and you should see your thermostat open up at around 180 degree's. Just do this on the stove. The water won't be boiling so you will be able to see it open up.
Hopefully its just your thermostat because they are very cheap(around 10 bucks).
If your thermostat is good and your fans kick on when they are suppose to then I would say its a water temp sensor or a sensor period.
I'll bet though that if you take your bike for a ride and when it gets around 215 degrees that your fan isn't kicking on to help the motor cool back down.
Hopefully this is the case and if it is you can just run the fan wires to your battery and hook up a toggle switch to turn your fans on whenever you please. This is just a bandaid fix and not fixing the real problem but it will get you by until you can fix it the right way.
Well I hope I may have been of some assistance and good luck,
Remember to check your fluid while the bike is running and warmed up completely, because if you just fill your radiator with the bike turned off it will only fill your radiator with fluid and not your motor as well(because the thermostat will be closed) which is what you want. Also after you fill your radiator when the bike is running and you can fill it any more let the bike run for a little while with the cap off to let any air in the cooling system purge out of the open radiator. You should see some air bubbles coming out of the radiator cap hole. If you have air in the system that will cause your bike to overheat as well. Had this happen on a Honda Car.
If you feel I did a good job answering your question please give me a fixya rating and THANKS!
