I have a kawasaki zzr 400 94'.the problem is it wont start after the engine is warm,i checked the carburetor overflow and it didnt solve the problem

If your Kawasaki ZZR600 suddenly stopped firing, there are several possible reasons for this. Here are some troubleshooting steps you can take to identify and resolve the issue:

1. Check the battery: A weak or dead battery can prevent the engine from starting. Make sure the battery is fully charged and has a voltage of at least 12.5 volts.
2. Check the spark plugs: The spark plugs may be fouled, worn out, or damaged. Remove the spark plugs and inspect them for signs of wear or damage. If necessary, replace the spark plugs.
3. Check the ignition system: The ignition coils, ignition module, and wiring may be faulty. Use a multimeter to test the resistance of the coils and check the wiring for continuity. Replace any faulty components as needed.
4. Check the fuel system: The fuel filter may be clogged, the fuel pump may be faulty, or there may be a problem with the fuel injectors. Check the fuel pressure and flow, and inspect the fuel filter and injectors for any signs of clogging or damage.
5. Check the carburetor (if applicable): If your ZZR600 has a carburetor, it may be dirty or clogged. Remove the carburetor and clean it thoroughly with carburetor cleaner.
6. Check the camshaft timing: If the camshaft timing is off, the engine may not fire properly. Check the timing marks and adjust the camshaft if necessary.

If none of these steps resolve the issue, you may need to take your ZZR600 to a qualified mechanic for further diagnosis and repair.

Not without a lot of work
try eBay international and import from an available country

Check the idle, and seems to need a carburetor job, get iridium sparckplugst that will help too. But carb is the main reason

Hey Heinrich,
Sorry.. but it sounds like the problem is still your carburetors.
I would replace the spark plugs AFTER you have a Qualified Professional clean and set your carburetors!! Also have the compression checked on all 4 cylinders....Sometimes low compression will cause a hard starting problem...

check your air filter...trust me...

hi, have you been told the carburetors are overflowing on can you see fuel leaking from the overflow tube, paul

hi buddy what temp does it reach when it starts overflowing ??

Its Starter relay may be causing main problem. You can try Yezdis starter relay as it can help you solving your problem
