If the key sheared it would not spark. That is what locks the flywheel to the shaft. If the flywheel doesn't spin no electricity is generated to make a spark.

it does spin, and gives a spark, just not at the correct timing. you could even tighten the flywheel to its axle without a key (in the correct position as with a key) and it would run, just would get out of whack if you'd run it hard, fast revs and hard engine braking would make it turn on the axle and so causing a wrong timing. |

My guess is backfiring is the key thing here. Means your ignition timing is off.

Replaced the cdi today and the bike runs fine to double check I put the old cdi back on and no spark spoke to John Shirt today at what was GASGAS uk and he said he?s not had many fail on the enduro bikes but a fair few on the trial bikes.
He said it?s not only a GASGAS problem as beta and sherco have the same issue he thinks it?s possibly a vibration issue so I?m going to fit the new one one a piece of foam. |

Alright.. dropped it off at the mechanic, he didnt do anything because he said he couldnt find any specs to test things too.
Im back to working this out on my own... I bought a multimeter, but thats about where my electrical abilities end. How do we go about starting to test this beast? |

Update:
I had the ignition coil off, utilizing my youtube skills i think i was able to determine that it works. I had the CDI off and i bent all the pins ever so slightly to make sure we had contact... also had the connectors right off the stator disconnected. Threw it all back together, to my surprise it had a spark. It was really weak, but it was a spark. Tried to start the bike it did the following: Started and died like it would during a failed cold start Started and ran for like 7 seconds, it was super rough and wouldnt rev, died very quickly Started again, ran the same as the first time Kicked it over a bunch more, nothing. Pull the plug off, check spark... no spark again. This certainly doesnt tell me anything, maybe one of you smarter people can chime in. Im a little frantic since my riding season is super short and ive already missed 3 weeks of it. Thanks guys! |

That?s exactly how mine ran before it packed up set your multi meter to ohms the red and blue wires to the stator are @14.5 ohms and I think it?s the black/yellow and yellow/green are @ 99.5 ohms if either are open circuit then it?s faulty but chances are the cdi has failed like mine did.

Thanks for the info.
The red & blue test just as you say they should. The rest of my wires don't quite match up the same as what you described. Attached is a picture of the harness coming off the stator. I've called around and no one even seems to know what specs this stator should be tested too. |

The 2 remaining wires in the 4 pin plug are for the pickup they should test 99.5 if the meter is showing open circuit that?s your fault the other 2 pin plug is for charging the battery and lights.
