Engine overheating

What model/type is your bike?
Is it water or air cooled?
Does it have a cooling fan?
Does it overheat when in motion or only in very slow traffic?
What indication do you have that it's overheating?

The solution will depend on the answer to these questions.

Overheated (3 hours gridlocked traffic), now pinging

put a multi meter on the battery, and check that the voltage when the bike is running is higher than when the bike is stopped, it may have spiked the regulator when jumped. I fit was jumped off a car the alternator tries to put out enough current to charge the car and this can stress the system

Hello, my bike was in the workshop for 4 months without movement. Now we tried to start the engine and it works with neutral position and with clutch off. Also it marks error code 21 (failure of...

The problem is probably failure of temperature sensor. The computer chip diagnosing your bike has found a problem. Some problems are not critical and the bike will still run okay other problems are fatal problems and the computer will not let the bike start until the problem is fixed. An overheated engine falls into the fatal category. Yes, I know the bike is actually cold, but the sensor is telling the computer differently. Replace the defective sensor and you should be good to go.

Zx12r overheating

Four choices in order of probability >
  1. The thermostat could be bad
  2. A cooling fan not kicking in
  3. A bad water pump
  4. A restriction in a coolant line or radiator

My cbr 929 honda is overheating how do i fix this problem

Check the coolant circuit that does not have air at all kept inside.
With the bike cold and the radiator cap open on the bike's kick stand start pressing again and again the coolant pipes and fill in coolant if you have to.Then start the bike without closing the radiator cap and keep pressing-releasing (like a sponge) the pipes until the radiator's lower pipe start getting hot.Then close the cap and wait with the engine running until you hear the radiator fan turn on.If you reach 227 F (108 C)and it hasn't start turn it off and check the temp switch on the radiator or the fan.
If the radiator's lower pipe never get's hot but the temp gauge shows you the temp reaching above 194 F (90 C) then you have a thermostat problem and you should check your cylinder head gasket too for compression failure.

If you did indeed overheat the engine to the point that is stuck, you would probably know it by the antifreeze being poured all over the ground. The bike would be really hot just sitting on it. It would smell like antifreeze and just smell hot.. I know, smell hot? but an engine that has been ran to hot has a pretty distinctive hot smell... It doesnt sound like an overheating situation if none of the above happened. A bike that is overheating will begin to loose power before it stops. LIke lacuna said, everything inside of the engine will start to expand from the heat and the piston will stick in the cylinder. Most of the time when this happens, the bike will cool off and restart. But, usually with problems. Warped or cracked head, cracked block, broken piston rings. These engines are aluminum and dont like to be overheated and warp really easy. If the engine is really hot, it will not turn over until it cools down enough. Im not saying it couldnt have overheated and then restarted without any problems, its happened before, but just not likely. But, if this is the case, take lacunas advice and change all of the fluids. Your oil will be nasty. Maybe get ahold of the previous owner and see if it has had any probems. It kinda sounds electrical to me. as long as the above overheating signs didnt happen. If you dont think it was overheating and it happens again, try to push start the bike to see if the engine turns over. even putting the bike in second or third gear just see if you can move the bike back and forth. If nothing else, you'll at least know its not locked up.

After it cools it starts back up without a problem? What is the color of the center electrode insulator on the spark plug? If the bike is overheating due to a lean air fuel mixture, the electrode would be white or gray in color. If the bike continues to overheat make sure you fix the problem quick because your engine will probably lock up for good before too long. When the bike is HOT and it shuts down check for spark... I've had some ignition coils fail after getting hot.
