Have no idea how this could have happened but now a lot of things make sense; the kick back, rough running, easy stalling etc. But the starting issue has to be of different origin, since the engine doesn't turn at all Anyway, thank's for the help so far, the battle continues... |

Well that's great news, a big step forward and explains a lot!
That's the 'Woodruff Key' that has sheared. The reason it's sheared is probably because the flywheel was not pushed securely onto the taper of the crankshaft, maybe the flywheel nut wasn't tightened properly? Maybe dirt/debris on the taper not allowing it to seat properly? Maybe damage to the taper on the crankshaft or taper on the flywheel? Before you fit a new Woodruff Key, carefully inspect both tapers, run your fingers around both tapers feeling for any damage or 'high spots'. All the best, Dave. |

So where are you at now, you have fitted a new Woodruff Key but the bike won't start?

No new woodruff key yet. Just today got the flywheel pulled.
And the starting issues are based on the starter not turning the engine over. This is probably due to the weak batter (new 240 cca battery coming as a guarantee) and high compression. |

OK, see what happens with new Woodruff Key and new battery.
Good luck! Dave. |

Let's get the credits organized. It was Jakobi who called out the flywheel keyway. This will have a significant influence on ignition timing. I was mentioning the stator plate location relative to the oval washer stamped with "T".
If the oval washer is modified, the stator plate can be advanced or retarded. Since the trigger (impulse coil) is mounted to the plate, any movement of the plate also throws off the timing.

Anyway, the important thing is you've found the problem...I hope your dealer/GasGas will be paying for the flywheel puller! Hope you're able to get out and enjoy your new bike very soon, it's a real shame you've had this problem, you've been very unlucky. But...look on the bright side...I guess you've learn't a lot about your engine! |
