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.

SOURCE: i have a kawasaki kx 250 2 stroke an it was

hi murray,

nice bike you have there.

have you checked on the carb ans see if the jet is right and the mixture is normal, this is usually the case if the carb is not tuned right.

better of reset the card, open it clean it, then set to default even if you are using your mixture of gas and 2t. just set to factory default. once it starts give it a few run, 1-2 hours, then set it to how you want your mixture to be.

hope this helps,

regards,

voodoo

SOURCE: no idle &bacfires on deceleration

hi mate on the carb you will find 2 screw 1 is for the idle and the over is for mixture the idle one will be the furthest out screw it in 1/4of a turns will the engine is running this will take the idle up on the engine and the backfiring is fuel in the exhaust not being burnt so on the over screw on the carb screw that in 1/4 of turns this will decrease the amount of fuel going into the engine if it still backfires screw it in 1/4 of turns again and see what difference it makes good luck

SOURCE: KLX 250 won't fire - new battery

-check the fuse right hand side below the fuel tank and seat, see if it is blown.
- Check to see if plug has spark, replace if necessary .
- Did you run the bike with a low battery before replacing it? could be that your stator is shot.
-Is bike trying to start but won't?

Timing


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.

Timing..I.E. late firing


Hi, Spiderman699 for backfiring the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a "LOAD" test "WARNING" you can have 12.5 volts or better but little or zero amps and the battery must be replaced.
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. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage check for spark leakage in the dark.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.

Hello I am having problems with my 2004 kawasaki kx 250f. The biggest problem of it all is that I am afraid of running the bike because I do not want to blow a head gasket. When started up the bike...


Starting problems on your bike are usually related to twisting the throttle too often. Remember, the carb has a diaphragm pump in it that gives a shot of gas each time the throttle is twisted. That means the engine can flood quickly if you get happy on the gas. Gently use the kickstart lever to ease the piston just past top center on the compression stroke. Now give a good strong kick. Repeat as needed.

Just got my self a 2005 kx250f was runing fine one day and now i cant start it changed air filter spark plug and cleand the carb it back fies alot


The valves probably need adjusting. This should be done periodically with four stroke dirt bikes. When my bike's valves need adjusting, it kills me trying to kick it, and it backfires a lot.

Another symptom I have noticed for valves that need adjustment is when I pull in the clutch sometimes, the bike will stall.

Hope this helps.

Just bought a 04 kx250f starts very hard and pops and backfires


Sorry, could be a clogged up carb from sitting or a bad ignition box. Have you got a pal with the same bike you could change out the carb to try? If the bike sat for quite a while, it almost certainly needs a carb cleaning and service.

1981 Wide Glide Bike is missing and backfiring


open up the ignition cover plate and check the backing plate. it may have come loose and threw the bike out of time.
make sure your plug wires are plugged on tight and the coil wires are secure.
It is most definitely a timing problem.
