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.

Please rate this answer. Thanks

! i would check the ground as on a ohm meter it will show it has connection but under load it will not have proper connection. 2 check the voltage regulator and that it dose not short and let a over voltage or over current happen as it will burn out the CDI when you first try to start it.

Ok i have a solution this happened on my dads 200cc roketa its a chinese bike but any way there is a thing on your bike called a cdi ignition which is like a second spark plug check and make sure that it is clicked all the way in if it helps cause we were dinking around with the carb and stuff but it can be just as simple as checking your wires.
