Take out the spark plug ,put the cap back on it and rest it on the engine, crank it over to see if you have a spark.
If you have it is probably carburation .

Hey whats up? Try back probing your wires going to the CDI unit with a volt meter or continuity tester to make sure you do have any broken wires. Then check the stater make it is good. If sure how to check the starter take it a bike repair shop they should check it for free.. If that does work let me know and I will look further into it for you. Good Luck.

SOURCE: 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.

Why is my 97 Honda 4 wheeler not getting fire


There are three items that are connected together needed to create spark on your 1997 Honda 4-wheeler, regardless of which model it is.
Before we go through a checklist of these three important parts, look for a black wire with a white stripe that runs to the ignition switch and kill button from the CDI box. Disconnect this wire before it gets to the ignition switch and kill button, then check for spark. The most likely cause is a broken kill switch on the handlebar, or shorted ignition switch. Such a condition grounds this wire and kills the spark.
If this test did not restore the spark, continue reading...
Here is what is required to create a spark.

First, the alternator has one coil which generates a high voltage--about 125 Volts AC for the CDI ignitor box.

Second, there is a pulse voltage generated once every revolution of the engine that goes to the CDI box. This pulse causes the CDI to dump its stored energy from the 125 volt line into the primary of the ignition coil.

Third, If the two connections of the wire that runs from the CDI to the Coil are BOTH SHINY clean, the ignition coil will generate a spark.

If any one of these 3 don't happen, the spark will go away. Of these three, item 3 -- one or two tarnished and/or dirty connectors -- is the most likely cause. Just an added resistance of 0.3 Ohms or more in the CDI to Coil connections will cause the ignition to fail. No other wires have to be this clean.

No spark at the plugs


the things i would check are the pickup coil, the ignition coil, cdi box, the ignition switch and the kill switch. I just purchased a 4 wheeler that they changed everything electrical on it. come to find out the kill switch was melted onto the muffler causing it to be always activated. if you get a repair manual or look hard on the internet you can get the proper readings to ohm test your pickup coil, ignition coil and cdi box. the ignition switch can be tested with a test light and the kill switch should not be grounded unless activated. (hook a test light up to the positive side of the battery and then touch the kill switch wire. if it lights up there when not in the kill position you have a problem)

There is no spark coming from the spark plug(new), there is power coming to the cdi, but none coming from the coil from the cdi unit


It sounds like either the cdi has become faulty, or it is imobilised due to either the safety switch on clutch lever, side. Stand, ignition switch, or engine kill switch, the only way to test the cdi is to replace it, some circuit tests on the unit may be possible, but only a new unit will eliminate the fault

Why does my engine cut off?


Possible reasons are;
  1. Water condensation in the gas tank has partially filled the carb float bowl. Bikes don't run well on water. Remove the drain plug on the float bowl to drain the bowl.
  2. Install a new spark plug to eliminate possible carbon shorting.
  3. Check the side-stand kill switch. Broken or out of adjustment it can intermittently kill the engine.
  4. A loose or dirty plug in connection on the power wire to the coil.
  5. Bad kill switch on the handlebars.
  6. An abraded kill switch wire or power wire.
Start at the top and work your way through the list. If that doesn't work you will need to go to the dealer and have them check the coil, CDI and other ignition components.

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.

No spark on Hyusu


Hi and welcome to FixYa,

For a "no spark" problem with a Hyosung RX125, check:
  • temporarily disconnect the battery. With the engine on at both the ignition switch and engine kill switch, verify that the green wire to the CDI does not measure 0 ohms to ground;
  • if it does, check the ignition switch and the engine kill switch;
  • it it measures anywhere between 50 ~ 500 ohms, then reconnect the battery and check that there is +12 on the orange wire going to the CDI with ignition switch on;
  • for a pulsating voltage (high ACV) at the white / blue wire coming from the CDI going to the ignition coil;
  • for a pulsating voltage (low ACV, 0.5VAC) at the green wire coming from the pulser coil going to the CDI; and
  • of course, check if the CDI (black / white) is connected to the ground.
Postback results of tests.

Good luck and thank you for using FixYa.

1980 Honda Cm400a No spark


Hi and welcome to FixYa,

Bypassing the kill switch means removing the connection of the black / white wire either at the emergency stop switch (kill/run), ignition switch or preferably at the CDI connector.

Additionally, you can try:
  • start with the side stand up;
  • check/wiggle the 6 wires coming from the stator going to the CDI.

Would appreciate a postback on results / updates.

Good luck and thank you for using FixYa.

Not getting fire from coil


Do you have a manual? If you do can you send me a copy of the correct schematic for your bike. It will me help you if you can scan a copy in to send me. If you don't already have a basic voltmeter that measures resistance. You should pick one up at either WalMart or even better Harbor Freight has the best deal $4-$9 there. What year is your bike? You can start off by isolating the kill switches from the coil by unplugging the coil lead headed towards on/off switch and other safety switches. The idea here is to make sure you don't have a bad switch by disconnecting all kill switches to test for spark. If still no spark does the bike have cdi box or points fire ignition. CDI is capacitor discharge ignition often refered to as the black box. Points are mechanical switches that open and close riding on the crankshaft.
Please send year of bike so I can better assist you.
Thank you,
Todd
