Question about 2000 Honda NSR 125
Hello, so i'm having a problem with my honda nsr. It doesn't have a spark. I already changed ignition coil, CDI, i tried CDI with french and GB connections but I still can't get it started. Any advice? :)
This may sound silly, but have you checked the safety switches? There's usually one at the kick stand and sometimes another at the clutch. If either is broken or a wire has come disconnected, the bike cannot start.

Testimonial: "I couldn't find any safety switch at kick stand or clutch, only under the seat, and that one was good. However I measured my alternator and there was about 70 ohms too much at black/red - green wire and 10x too high ohms at all three yellow wires. So is that ok or is my pick up or my alternator broken?"

SOURCE: 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

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.

I would first try a new plug, then coil. If this is the original coil, it is not unlikely that is your problem. Check and see if a small engine shop near you might have a tester for a coil. That might help, you can also find a coil on ebay pretty cheap.

you have a bad fuel pump. your fuel pump gets turned on by the blue wire that runs from your coil to your spark unit thats why the fuse never blows with the coil disconnected. i had the exact same thing and wasted a lot of time looking for a short that was never there and even tried a new spark unit and fuel cut off relay before i replaced the fuel pump.. fuel pump 65.00 money wasted on other things 350.00 and a lot of time. have your fuel pump tested with a 10 amp inline fuse and if it blows then u will know for sure
