kawasaki KX 250 - Popular Questions, Answers, Tips & Manuals


Hi, Howard and the usual suspects are:
1. Fouled spark plugs.
2. 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 preliminary 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.
3. 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.
4. Loose connection at the ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting/leaking, spark plug cable connections loose check for spark leakage in the dark.
6. Faulty ignition coil or electronic control module.
7. Faulty pulse coil.
8. Faulty CKP, CMP, or BAS sensor.
9. Faulty ignition switch.
10. Faulty run/off switch
11. Tilt sensor needs a reset.
12. Security alarm failing to disarm needs reset

most ignition problems are simple 3 parts - fuel / fire / air

from everything you've already worked on, it seems you must set your IGNITION to FIRE on time at higher rpm .

First, did it break or is it bent or is it stripped? These all require different approaches once you get the right side of the engine clear, clutch removed, etc... TAKE PICTURES WHILE YOU ARE DOING THIS to make sure you put everything back where it belongs. Do you have a clutch hub holder? (IMPORTANT) Do you have a air wrench, you will have a large clutch nut (24-26MM?) to remove and then reinstall the nut with the correct torque! If you do not have these tools, PLEASE take it to a PROFESSIONAL. He will have all the tools necessary. If the shift shaft is broke or bent it is going to be more difficult because it is a tight fit through the engine cases, they are aluminum and they will break if the shaft is forced out!! You will have to carefully saw the shaft off CLOSE to the case as possible before attempting to remove it.
If its just stripped, it can be filed or sanded down, cleaned, and removed easily. Change the shift shaft seal too!!!
If this is your first time to try this... and you don't have any of the tools I mentioned, PLEASE take it to a professional!!

Sounds like a valve timing problem to me. Put the engine at TDC (top dead center). There will be marks on the cam gear that should be aligned with the top of the head casting. This is something that could be damaging to the engine so be careful. A manual is a good investment.

remove stator cover and flywheel (puller required), verify crankshaft key is not sheered, and stator plate is in its proper position. There is no timing mark on that flywheel because it is irrelevant and not needed.
This is most likely not a flywheel timing issue but a CDI timing issue. The CDI timing is governed by the TPS switch on the carburetor telling the CDI when to change timing maps and curves. If the carburetor is dirty and you cranked up the idle to run off the main circuit instead of the proper idle circuit this can happen. Or you have an improperly set, or failed TPS switch on the carb.
