What gives a dirt bike spark?
You see the CDI releases a DC electrical charge into the primary side of the coil. The primary side of the coil is basically small coil of wire. Making this high DC voltage jump from the end of the electrode to the grounding tip of the spark plug is what produces the actual spark.
Why does my dirt bike have no spark?
However, the wires should have continuity with themselves at the system. A wire without continuity creates an open circuit, which will cause the ignition system to act as if the pickup coil is faulty, resulting in a no spark condition.
What does a blue spark mean on a dirt bike?
The very first place to start is your spark plugs. To test your spark plugs: Remove plugs from the cylinder head. Plug them into the plug cap. Holding the plug up to the head bolt, turn over the engine. A yellow or blue spark bridging the gap signifies that the spark is strong enough to ignite the cylinder’s fuel/air mixture.
What to do when your dirt bike won’t start?
Turn the bike over by kicking it, or with the electric starter, and you should see the plug sparking. If there’s no spark then the first thing to do is to try a new spark plug. If the new plug sparks, put it back in and try starting the engine. If it doesn’t spark you could have a more serious problem.
Can a bad spark plug cause a bike to not start?
Unfortunately, the problem of a bad spark plug isn’t that common, especially in four-stroke bikes. Furthermore, your routine maintenance should catch this issue before it becomes a significant concern. Sometimes, the spark plug may be okay, but the connections to it are faulty.
What to do if your dirt bike has no spark?
To fix a dirt bike with no spark, you must remove the spark plug from the cylinder block, put it back in the ignition coil, and kick start the bike to check for the spark. If there is no spark, replace the plug with a new one and double-check all the electric components and repeat the process.

What causes spark plug to foul on dirt bike?
If the plug tip temperature is too cold when it sparks, carbon, oil, and combustion products can cause the plug to foul. If the plug tip temperature is too hot, you’ll get pre-ignition — the center electrode burns, and you may damage the piston. Heat range is altered by changing the length of the insulator nose.
What does it mean when your dirt bike wont start?
If any liquid comes out, it means that everything is okay and the fuel is getting to the carburetor. However, if nothing comes out, then it means that the fuel valve is probably turned off. If everything is okay, think about the last time that you filled your gas tank.
