Question about kawasaki ZX-9 R Ninja Motorcycles
I have 1994 zx9r it overheats my fan switch doesn't kick on so I bypassed it by jumping the two leads & added an on-off switch so when it gets hot I turn it on, but it gets hotter with the fan on when im @ a red light, what's wrong @
Hi, Dshih04 and the usual suspects are:
1. Low coolant level.
2. Restricted radiator air flow.
3. Faulty thermostat.
4. Coolant pump or fans inoperative.
5. Vent hose crimped.
6. Air in the coolant and needs bleeding.
7. Engine idling too long or bike moving too slow.
8. Coolant too old needs to be replaced.
9. Faulty temperature sensor, wiring or connector.
10. Radiator veins clogged or corroded needs repair
11. Ignition timing retarded.

Could be a few things.If you check radiator fan and its ok move down to the thermal power switch usualy at the bottom of the radiator.Make sure you have power in and out of the swich when the engine is at operating temp.Use a test light/probe easy to use and cheap to buy.If the switch is ok the next step is the relay in the box with lid next to the battery.Sometimes just pulling the relay out and putting back in will fix the problem due to poor contact.To sum up its usualy the thermal temp switch but check every thing else before wasting money on the wrong things.Good luck

your motherboard in the lower rear area of the unit is bad,if you have recently replaced burned out lights in the refrige when these lights burn out it causes a surge on this control board and burns the circuit trace,hint:if you hear a rapid clicking noise in this area of the motherboard its a relay trying to latch,a bad board wont let it latch and the lights will dimly flash in the refrige compartment and the digital read-out may be out too
