    I figured it out it was just the battery was going bad. It would crank the motor just fine but didn't have enough power to crank the motor and run all 4 coils too..new battery and no problems

Hi, Larry and the usual suspects are:
1. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a cursory reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Spark plugs in bad condition or partially fouled.
4. Spark plug cables in bad condition and leaking check for spark leakage in the dark
5. Spark plug gap too close or too wide.
6. Faulty ignition coil, module, and or sensor.
7. Loose, dirty, or corroded ignition module connector at crankcase.
8. Faulty CKP or CMP, MAP, ETS, ATS, TPS, O2 sensor.
9. Dirty air filter.
10. Intake air leak.
11. Water, dirt, or rust in the fuel system.
12. Carburetor contaminated, sticky float, plugged jets.
13. Carburetor has oil in the bowl due to excessive oil in pre-mix.
14. Carburetor vacuum diaphragm torn, cracked, not seated or installed improperly.
15. Multiple carburetors out of sync.
16. Fuel filter clogged.
17. Old or contaminated fuel.
18. Fuel tank vent system plugged or carb vent line closed off.
19. Gas cap diaphragm valve faulty.
20. Vacuum line from the intake manifold to fuel valve is broken, cracked, pinched, or missing.
21. Carburetor controls misadjusted.
22. Incorrect valve timing.
23. Valve springs floating, weak, or broken.
24. Damaged intake or exhaust valve.
25. Incompatible performance parts.
26. The control module may be in "LIMP" mode
27. Check for engine trouble codes.

    someone told me that the carbs prob need to be rebuilt and to check the plugs to see how they are i found plugs 1&2 was black and drenched with gas and plugs 3&4 was crusty white on the tips i put them in new 3 weeks ago they are ngk premium so i swaped them out with the ones that was in the bike when i got it and the bike fire right up just fine so i shut it off and started it again fired up i did that 3 times and all 3 times the bike fired right up just fine. im hoping thats all it was but im still going to get the carb rebuild kit and a jet kit because i dont like the way 1&2 was running rich and 3&4 was running lean. any thoughts on what jet kit i should use on a 2000 zx9r with a full muzzy stainless exhaust and header

2000 ZX9R Bike overheating and the coolant comes out of the reservoir top line.


make sure that the thermostat is working and opening to let the flow of water in the engine, if it's ok you should start it and let it warm up and see if the cooling fan starts when temperature reaches close to 98 degrees, is it doesn't and the coolant boils then you have to change the temperature sensor as it is faulty.

Hi, Dandanthegen for this scenario you will need your service manual that has all fastener torque specs and a wiring diagram on the back pages, parts fiche, and owners manual if you can't find the best tool you ever bought for your Kawasaki, despair not, for a mere zero $0 you can download another one.
