Other Cracked flywheel

[cully37]

Quick backround...all last season I would end up with a dead battery after a day of riding. The batteries were not bad, just not getting charge. I pulled the flywheel thinking the stator was bad and this is what I found...cracked flywheel. There are grooves and it is rough all around the inner circle. Would this cause it not to send charge? Any advice on this situation would be great.

Alex of PFM Industries on here and Facebook can replace the hub for you. Someone post his user name, can't remember this second.

Could this have anything to do with it not charging or should I still lean towards the stator?

What do the coils on the stator look like?

Test the resistance of the charge coil with a multimeter, this will give you your answer.
Did the spring break in the starter bendix or a bolt fall out of somewhere?

 

[cully37]

Not sure about the spring or bolt...do you see something I am missing?

It might just be alot of shrapnel from the flywheel rubbing but It looks messy in there. I've had some starter bendixs fall apart and that looks like the mess they make.
It looks like there is a magnet or a chunk of something stuck to the trigger coil in the picture

This wire looks suspect as well.

besides the flywheel, you also need a stator. All 3 coils look sad. The lighting coil (that's the one for charging the bat.) seems to have cut wires. The small pulser coil, as pointed out in post # 11 has a damaged wire. The charge coil- that's the one that charges the caps in the CDI for spark- is sort of brown in color and likely wont give you a satisfactory resistance reading.

Thanks for all the help guys, I appreciate it. It doesn't look like Speedysprocket has the hub I need so back to the drawing board. Not what I expected to see when I pulled the flywheel.

I agree. Your stator needs replacing or some help. I would remove it and clean both stator and front cover area very well. That is a 62t stator, was the flywheel a 62t?

 

[cully37]

Yes,62T

Going to have to contact jetinetics on that one. Hopefully they'll sell you a hub.

 

[cully37]

I called and left a message with them. We will see what happens.

I would just send that stator out to be refurbished then you know its good, and pick up a flywheel from speedy make sure your bendix is ok and ride with no worries . You probably wont feel much difference with a lightened oem flywheel anyway and they rarely break .

 

[cully37]

The good news is that I talked to Jetinetics and they said they will fix the flywheel. Rebuilt stator and new bendix is the plan and hopefully no more dead batteries. Luckily I always ended up dead at the beach and never got stranded last year.
