O2 sensor in muffler system not registering CPU shut down

More likely is a head gasket. A temp sensor reads liquid temp, and with air being pumped into the system will give you a false reading. Are you running a 50/50 mix or anti freeze? Pure antifreeze will actually allow an engine to over heat, however you usually see it on the gauge.

If it was stored for the winter the high speed jets are probably gummed up. This is at least worth a try. Go to an Autoparts store and buy some Sta-bil, that is a brand name fuels gel and varnish remover. I often find this is all that is necessary to get a unit running right after storage. Mix it a little stronger than one ounce to five gallons. good luck hope this helps.

connect the earth first then the power side.

Drain the gas from the tank and carbs.(there are drain plugs on the bottom of the float bowls on the carbs) (to drain tank you will just need to unplug the hose that runs from the tank to the carbs and open the filler cap after opening the petcock) Put everything back together and fill with fresh gas and try to run it. If this doesn't work then you will need rebuild the carbs by just replacing the main jets in your carbs because they may be shot. If you still have problems after that then check the float bowl height on each. You will need a repair manual for that bike to get those measurements. Good Luck!

Either your throttle cable is stuck, or the idle screw is turned up too far.

must be running to rich.sounds like the carb needs adjusting

First check if the fan does work directly i.e. remove the wires that goes to the fan and run another wire from the battery to the fan and see if it works, if it works than there is a problem to the fan actuator switch fitted around the cooling system.You may have to replace this switch.

Sounds like the idle is out of adjustment. There should be a knob with a phillips type screw on a cable that can be reached on the left side of the bike. Turn it counter clockwise to lower the idle.

could be i hade same problem on a 07 gsxr and it was the fuel pump so try changing that

POSSIBLY (if present - happened to me on a different bike) a mechanical link between choke and throttle got stiff so 'choke' (the 'a bit more throttle' component) kept the revs up.

Turn the engine over a couple of times.

Water in engine oil is a problem mechanic should look at before damage is done.

DISCONNECT NEGATIVE CABLE FROM BATTERY IF BIKE STILL RUNS ALTERNATOR IS ON.

Buy a manual, all the information you require to service your bike is in there. But as long as you buy the plugs recommended in the manual they will be close enough to the right spec for your bike.

is choke sticking

Check that your air filter is fitted properly and then check the spark plugs, you may have got a poor set of plugs-they sometimes fail when under stress ie high revs.

Check the bulb.

Pull the wire from the horn and check for voltage when you press the horn button. If you have voltage 12vdc. the horn is bad. Check to be sure there is a good ground to the frame and in the wiring. If you have two wires, one is a ground, one is hot from the button when pressed.
