Flywheel too light to charge battery and run lights?

Le_Thon · 04-12-2014, 10:36 PM

I have a full light kit on my bike as well as electric start. I was perplexed for the longest time as to why my battery would not charge and the lights were always dim. I replaced all the components of the charging system to no avail.

It then came to me that my flywheel might be too light. I believe I have a YX 125cc engine. has anyone else had a similar problem? I would like to increase the weight of my flywheel but I do not know where to start.

Anyone have any suggestions?

There's 3 phase stator for commonest chinese bike. http://item.taobao.com/item.htm?id=3630414870. What's on ur bike?

Sorry for the late reply. The one I have is at the link below. Or at least it looks identical.

After reviewing the stators, I am guessing mine does not have enough "poles" to generate the power required for the lights and the battery?

Do you own a dirt bike, or a dual sport bike? Did your bike have a headlight as stock equipment? The stator in the photograph is typical of one installed in a dirt bike which doesn't have a headlight.

Indeed, that type of stator doesn't have sufficient poles and wire windings to produce enough electricity to charge a battery and power a headlight.

ALL DC. Needs dc-cdi.

The picture attached is how my bike came from the factory. It came with the light kit on there. It came with a regular dirt bike stator.

I wish I would have known this years ago! It kept me from riding it on the street and only on the trails :(

I see the direct fit link, but how do I purchase from TaoBao?

Also, thank you very much!!!!!!!!!!!!!!!!!!!

Do you guys think this stator would fit even though it is for a gy6?

I am very excited about this! I have been trying to figure this out for awhile and now I believe I have it solved thanks to your help.

I really do appreciate this.

This type needs NEW flywheel cuz the magnetic line is different.
"ALL dc/ 2 coils" above is fastest way if the flywheel still in working order.

With the 2 coils, I do not think there would be enough power generated? I have a 2 coil stator now but the only difference between the two is that the one you suggested is a 4 wire and the one that I have is a 5 wire. I do not know much about electronics :( You can compare the wiring diagrams in the link below. Let me know.

(ALL DC / 2) is 120+ watt cuz BOTH coils generates power to rectifier.

I am looking at the all DC and I am wondering how I hook it up to my 5 wire system. I am sorry for the late reply, I just got super busy!

From the wiring diagrams it looks like the blue/white cable is the same from the 4 to 5 wire system. The black/red cable does not exist in the 4 wire system. I am assuming the black cable is the ground. The only problem I see is that there are two yellow cables in the all DC 2 coil one. Are these two yellow cables the yellow and white cables seen in the 5 wire diagram?

Le_Thon · 04-24-2014, 05:27 PM

I actually had a crazy idea. I have two complete stators and I was thinking about combining the two larger coils that I have. Ill attach pictures of what I am thinking. Please let me know what you think.

The new stator has both the lights/charing running off the same large coil in picture 1. The little black coil just has the red/black wire that runs to the CDI.

In picture 3, I am thinking about having one of the coils charge the battery while the other coil runs the lights and is hooked up black/red cable that runs to the CDI. The only problem I see with this is that there might be too much power running to the CDI.

The following pictures -
1. New stator that I bought months ago to try and remedy the issue
2. Coil salvaged from other stator
3. What the new stator looks like (No wiring/soldering has been done yet)
