Good news,

I figured out the issue and it 100% was my CDI. The EB the eBay CDI do work, but they have a different pin set arrangement. You can look up the typical DC CDI pinout I verified the orientation by by the two ground prongs using my ohm meter. I marked up a harness adjusted the plugs and I got spark.

I hope this helps out anybody facing issues getting a new CDI or having no spark because for some reason after all these years, it’s hard to find a resolution through the forms. I don’t know why Kymco Has their own proprietary arrangement maybe just to sell parts!

Hope I save someone a headache or some money!

Premix is a better idea for oil with a bbk. Otherwise you are getting a lesser mix of oil (more air per rpm, more fuel, same oil flow.

I believe it is the same on most similar bikes. On the super 9 i did it looked just like a gy6. I did it like so

Disconnect oil line from pump inlet and drain.
Remove hose between pump outlet and intake manifold.
Remove throttle cable connection from pump (wrench to loosen the nut)
Remove the single bolt holding the pump in.
Pull out the pump housing. Slide off internal shaft. This will not go back in.

Reinstall pump housing. You can either cap the nipples with vacuum caps or what I did was I cut the hoses short, and found bolts/screws to slide over one end, and zip tied to seal off the ports.

Similarly seal the port on the intake manifold and you are good to go.

It is probably overkill sealing the pump inlet and outlet, but I think that without the shaft, you dont have a full seal so better safe than sorry. The intake manifold nipple will need to be sealed, however.

Boom, job done. Took me like 10 mins. I recommend removing your seat to get to it

Hello,

I hoped to hit a larger audience than just my scoot, as I believe all Kymcos with a DC CDI operate the same. I have an 05 LC S9. Thing was fine I got it running for the first time on a while, and it had some downtime as I waited on parts to refresh.

Fast forward a few days and I got the carb back on after a rebuild, and other assorted goodies. I had to run the starter for a bit to prime the bowl (vacuum petcock) and that is where all went wrong. I am not sure if the voltage dropped too much and something fried, but my battery got pretty hot. I took it apart and assessed, all looked fine, fuses were good.

Rehooked battery, 12.8 V - now no spark.

See testing conditions and analysis below:
CDI: 4 wires in: 12.8V DC from battery - check. 1V AC from trigger coil when cranking - check. Ground is good, continuous, same for coil lead.

Coil looks good, resistance is on point. 0.1-0.2 ohms primary, about 5k ohm without the cap on the secondary and 8k ohms with the cap. All within spec.

CDI: no way for me to diagnose. I have tried two from ebay. One DC generic and another that stated it was DC, for the Dink, S9, Agility and so on - no dice.

I have no way to read if there is a signal from the CDI to the ignition coil. Would this be a readible voltage? Not sure if it is too fast to pick up.

I have tried a separate working battery from my lawn mower, and I have another ignition coil coming in, but I am still confused. I don’t want to just change parts in this situation. Also an OEM CDI is over 100$ plus dealing with a Kymco dealer and waiting on shipping.

I have tried other plugs as well, and ensured they, and my motor are grounded properly.

Do I need to look into the voltage regulator, rectifier or stator? I assumed as long as I had my 12.8V and my trigger signal (with an assumed working CDI) I would have spark.

Additionally, any recommendations for a CDI are appreciated. Any luck with Naraku?

Yeah I think I made off pretty well. Fresh 70cc kit, multivar and delta clutch altogetheter for about 360 after tax and shipping. A 70cc kit alone is 285$ on racing planet, 100$ for the multivar variator and $100 for the clutch without the bell.

Malossi store is a direct subsidy of malossi but they use local vendors to fulfill orders I believe.

I might be too late! I believe it is a T5 aka 74 bulb. Going to get an led set to try out and will write back.

Has anyone ordered directly from the Malossi store before? I put in an order, paid, got an error, and now I have a credit charge and no email confirmation of the order or shipping information.

I filled out a contact forum yesterday, hoping it has either went through or they will get in touch. I just wanted to know anyone else’s experience with them. I figured it would have been better than going through a secondary vendor.

Also I have heard that GY6 parts may work for this, any verification on this?

UPDATE: GY6 Starter parts fit perfect!
