Answer 1

--It could be a bad pulse coil. It's at the flywheel and acts like a set of points. It sends a signal to the CDI. The pulse coil could be bad or unpluged.
--Could be a bad CDI box.
--Could be a bad kill switch. Always in the off position. Dirt bike kill switches are cheap and easily damaged in a fall. Try unpluging it (it's a grounding switch).
--Could be a bad ignition coil. Easily tested with a multi-meter.
--John B gave a good answer about the spark plug cap not making a good connection. Unscrew it from the wire. Cut 1/4" off the end of the wire and screw it back on.
--Could be a bad spark plug cap. Pull one off your car or lawn mower and try that one.
--Buy a shop manual to learn all the tests to perform and the specs each test should give.

Tons: 'What we once thought we had we didn't And what we have now will never be the same So I call upon the author to explain.' --Nick Cave's 'We Call Upon the Author' 'If your life is a leaf that the seasons tear off and condemn They will bind you with love that is graceful and green as a stem' --Leonard Cohen's 'Sisters of Mercy' 'But I tell you, I tell you, I tell you we must send away We must try to find a new answer instead of a way' --Jim Morrison (more from Zarathustra than Birth of Tragedy) 'Some women wait for Jesus, and some women wait for Cain So I hang upon my altar, and I hoist my axe again. And I take the one who finds me, back to where it all began, When Jesus was the honeymoon and Cain was just the man.' --Leonard Cohen 'Last Years Man' I'll stop now. I think almost any Leonard Cohen could make this list. Dylan and Kobain have some good ones too.

Answer 3

Sometimes the wire cap (the part that fits on to the spark plug) twists off. Try removing the cable, push a spare spark plug until it snaps on, and turn it clockwise a few times. There can be a number of failure modes, but this does happen quite a bit and costs nothing to check. Good luck.

Answer 4

If it was running but suddenly quit, I would check the kill switch or check for a disconnected wire that may have been caught on a branch or something. Trace the ignition circuit and check for continuity.

Answer 5

the best answer i could tell you is bad plugs, bad plug wires, bad CDI box, or bad coil, try all of those parts

Answer 6

could be a bad stator. I have had very bad luck with stators.
