Check the fuses. Is the kill switch on or shorting out? Disconnect it and then check for spark. Sidestand/centerstand should be up, Got a good battery?

I am unfamiliar with your Keeway and just trying to help. Don't give me a bad rating if I miss the mark on this one. Thanks.

No Spark, No Power coming from CDI to coil


Check the wiring on the connector plugs make sure all the wires are the same color on both sides, red to red blue to blue and so on. I had the same problem After replacing a stator and just plugging it in,after two weeks a new cdi and coil i noticed there were two wires transposed.

NO SPARK ON A 98 RM 125


Hi and welcome to FixYa,

Initially, test for the presence / absence of below described voltages using an analog / needle type voltmeter when starting the bike:
  • pulsating low AC voltage coming from the pickup coil;
  • pulsating voltage feeding the ignition coil.

Good luck and thank you for asking FixYa.

Bike wont fire. has no spark


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.

Wont start


Check the fuses first. Next, check for spark but with a new spark plug. Is the kill switch on? Does the side stand have a kill switch? Is it working properly? Tip-over kill switch on your bike? Check the operation of the ignition switch and all kill switches with a volt ohmmeter.
Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center casing. If still no spark, get CDI system and coils checked at the dealers shop.
