Check the side stand kill switch, battery, wire connections, neutral switch and clutch switch if your bike has one. If still no spark have the dealer check the electronic ignition.

No spark


I am thinking that the kill switch on the handle bars is in the kill position. Most bikes have on the rh side that you can flick off in an emergency and it kills the motor. many times I have been caught with mine as it can move when you are pushing out the bike.

1983 yamaha xj 650 no spark already changed the cdi coil plugs wires and mag pick up what next?


  • Do you see spark? If not, check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the side stand kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it.
  • Is the handlebar kill switch on? Is it shorted out?
  • Are you getting power to the coils?
  • Check the fuses. How good is the battery? Try a jump start from your car battery.
  • 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 or side casing. If still no spark, get CDI system and coils checked at the dealers shop.

MY 125cc 4 STROKE JUST CUT OUT FOR NO REASON, AND NOW I CAN,T START IT UP AGAIN! I MADE THE MISTAKE OF GETTING ONE OF THOSE CHEAP CHINESE SCOOTERS AND THE MANUAL IS IN PIGEON ENGLISH. THE ENGINE WILL TURN...


Even though I am unfamiliar with your bike I will give this a try on the condition that You give me a "Helpful" rating or better. Like you, I am unable to comprehend pigeon English.

A spark plug can go bad at any time. Get a new plug. Put the wire on the plug then ground the metal side of the plug against the cylinder head as you press the starter button. Look for the spark. If no spark, check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it. Check the fuses. How good is the battery? Is the handlebar kill switch on? Check the operation of the ignition switch and all kill switches with a volt ohmmeter.

No spark


Check the side stand kill switch if your bike has one. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it. Check the fuses. How good is the battery? Try a jump start from your car battery. Is the handlebar kill switch on? Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Install new spark plug.

If that doesn't do it, 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. You can screw up a CDI unit checking it yourself.

No spark 110cc engine wont start


Check the fuses. Next, check for spark but with a new spark plug. How good is the battery? If needed, add water to the battery cells enough to cover the top of the cell plates.Try a jump start from your car battery. Is the kill switch on? Check the operation of the ignition switch with a volt ohmmeter. You should be getting power into and out of the ignition switch.

If the bike doesn't start and run properly check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. Broken or out of adjustment, it would kill the spark. Check for a broken wire at the switch or coupler. Get a service manual and check out the electrical section. Some bikes have a diode integrated into the turn signal relay. Try moving the kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it. If that doesn’t work, check out the relay.

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.

I have a YFM 200 (four wheeler) and am getting no spark. Have changed the plug, it turns over well, where do I go now? I have a 1986 version. Sorry, can't find this under "choose product category", but...


Check the fuses. Next, check for spark but with a new spark plug. How good is the battery? "Some juice" does not always translate into having enough juice for a spark. Fill the battery cells with water covering the battery plates. Jump start from your car battery. 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.

Bike shut off on the freeway and wont start again.


Got gas? Got water in the gas? Drain the carbs and fuel line.

Check for spark. If no spark then check again with a new 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.
Are all wires clean and with a solid connections? Check the loom. Any abraded 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. With a little luck this will get you back on the road.

NO SPARK


I don't know what has been done or checked so some of the following may not apply. Electrics are not my best skill but I will share what I know.

How good is your battery? A low battery can kill spark. Get a new stock spark plug for your bike. Test for spark by grounding the threads of the plug against the cylinder. Have a friend kick the bike while you watch for spark. Assuming no spark, then check the handlebar kill switch with an Ohmmeter to be sure the switch is working properly. Some bikes have a side stand kill switch. Check your bike and check the switch. Sometimes the switch goes bad.

Check the wiring harness, even under the gas tank. Are all the connectors clean and with a tight connection? Any abraded wires? Check the ignition switch also. The switch can go bad as well. Are the flywheel coils good? That's my best when no spark is present.
I hope this helps.
