04 125 Intermitent Spark

Update: Received the new coil from RYP and installed accordingly. Same symptoms.... Talked to RYP today and need to verify if flywheel key has sheared or not. Wouldn't you know it my puller is at my buds shop. RYP was very generous to offer a refund on the coil since that was not the problem. I am going to keep it as having a spare is not a bad idea. I did test the stator per the SplatShop instructions and all the test show my stator to be good. The readings were on the low side of what SplatShop has posted but they were all within range. The other thing I have noticed is that the bike starts with an obvious kick back whereas when it was running good I did not notice this.....more to follow.

Well, that pretty much sucks. Double checking the flywheel is good, yet from what you have described? but you gotta go there anyway.

Seems the coils seldome fail, so I would let him have it back, just part of the process one cannot overlook. Even sheared keyways are fairly rare, and in your case claiming intermittant spark? because a sheared key still fires, just at the wrong time, so in most cases you are back to the stator, and what I suspect the erratic operation of the hall sensors, yet no way to test in operation.

Ryan is always good to work with and helpful. I do not know if he has any rebuilt stators, but as I understand you can get just a stator new now, where as in years past one had to get the pricy rotor assembly. Gotta ask him?

Udate:

Pulled flywheel and woodruff key is not sheared in any way. Time for a stator....

Update (praying this is the last one):

Received and installed new stator and flywheel from RYP (somehow RYP does not sell stator only like SplatShop). Bike runs perfect!!! It seems like it is also running cooler as the fan does not cycle on near as frequently as it was with the old stator. Still need to verify it is working though.

Upon removal and inspection of the old stator there was a nick in one of the white wires so I am not sure if this was grounding out or what. As you can imagine I did not want to fix this wire reinstall with all the other components (coolant, radiator, exh header, etc.) only to still have the issue and have to pull it apart again.

In any event she is running and I can now ride it with my son!!!! Thanks for all the replies.

Oh good then, finally get her going! These things seem fairly rare, but such a pain!

I doubt the white wire was it, as that should be the ground circuit.

Let me know what you want to do with the old stuff, may send it off for repair.
