Bad Stator Fix - Instructables

possible but check that after you check the operation of the "kill" switch

Stator will stop the cdi from firing the spark plug and either cdi or stator if bad will stop a spark from being created. The coil, wiring, kill switch and other things can also stop ignition spark.

It's a grounding problem

If your 125 pit bike skyteam is not sparking, even though you've tried everything, there could be a few different issues causing the problem. Some possible causes include:

1. Faulty ignition coil: The ignition coil is responsible for creating the spark that ignites the fuel in the engine. If the ignition coil is faulty, it will not produce a spark.
2. Stator issues: The stator is responsible for generating power to the ignition coil. If the stator is not working properly, it will not produce the power needed to create a spark.
3. CDI issues: The CDI (Capacitor Discharge Ignition) is responsible for sending power to the ignition coil. If the CDI is not working properly, it will not send power to the ignition coil, resulting in no spark.
4. Spark plug: A fouled or worn spark plug can prevent the engine from starting. Check the spark plug and replace it if necessary.
5. Wiring issues: A problem with the wiring can prevent the spark from reaching the spark plug. Check all the wiring connections and make sure they are clean and secure.
6. Battery: A weak or dead battery can prevent the engine from starting. Check the battery and charge or replace it if necessary.

It is possible that one or more of these issues may be causing the problem. It is recommend to check the owner's manual for troubleshooting and further guidance. If the problem persist, it is best to take it to a qualified mechanic for diagnosis and repair.

Sorry but they either work or they dont.
If yours isn't working, replace it.
But before you replce it consider checking the other components, because ign mods are exspensive.
it sounds like you've been already checking the other stuff. heres what i'd check if your bike came to my shop.
1. battery fully charged, and can take a load. (weak batteries = weak ign power)
i have a bike that won't fire at all with weak battery. Make sure battery is good.
2. check for spark at plugs, make sure plugs are good. Pull plugs and turn motor over.
rest plug next to head and turn over, do not touch the plug while turning over
or you can be shocked.look for spark.
if you have spark , then you ign mod is working.
if no spark, then check #3
3. power to coils. check the power going into coils,
if power but no spark, then coil is bad.
if no power. check #4
4. power to coils comes from a ignition system ( points/ cdi /ign. module)
there is a stator and a rotor. and a signal generator. on your motor
the signal generator wire sends a signal to the cdi, every time the rotor rotates.
the ignition system (ign.mod) sends power to coil.
so if no signal to the cdi, then signal generator is bad
if signal going into cdi but not sending the power to the coils then the cdi/ ign. mod is bad.

Hope that helps

The Voltage From The Stator To The CDI Should Be Around 40 Volts(AC) At Cranking Speed. Be Sure Your Meter Is Set For (AC) Not (DC). The CDI Changes The (AC) Input Voltage To (DC) Output Voltage To The Primary Terminal At The Coil. An Electrical Shock Hazard Exist If Stator Voltage Is Checked With Engine Running. Always Perform This Test At Cranking Speed (R.P.M.) For SAFETY. 120 Volts (AC) Can Be Present With Engine Running.

If you are able to use a digital volt meter and work your backwards from spark plug wire to coil to cdi to stator you can figure out where voltage stops.thats a fairly newer bike unless you really submerged that bike under water i dont think its the cdi box.it could be coil wire it could be coil.you want to check or change the cheaper parts before you go right to cdi because there not cheap.I have a yamaha banshee 350 and she was breaking up real bad.I thought because it was only happining on top end that the cdi was breaking down or stator was going bad.Found out with meter it was the coil wires and spark plug boots.These items have to have a certain amount of resistance or the do not conduct correctly.And spark plug wires and boots are not that exspensive.So thats why I say start from sparkplug boot and work your way back.Try that and Good Luck.

Sounds like you have all the right new parts. I would double check the wiring. Sounds like that is where the problem is at unless the new coil is bad.

There are a # of things that can take your spark out, first I would see if you have power to your ignition coil (100V+). If none there you need to isolate your ignition switch (unplug it or take it out of the equation) and jump your starter solenoid manually or try pushstarting the bike. If still nothing check for voltage going into your CDI box, if none check for voltage out of your stator (over 100V) and your trigger or pulse coil (over 3V). If you find voltage at the stator and not the trigger replace the trigger and vice versa. If there is voltage for both replace CDI box (but be cautious to verify good ground for CDI box and ignition coil). If you find voltage out of your CDI box (over 100V) replace your ignition coil. Good luck!
