CDI Help...I looked all over...

[Rando]

Hey everyone, I looked all over for the answer to this question and I have no luck. I want to buy a performance CDI and coil for my bike. The bike is running rough at idle, shuts off often, even after riding for 20 mins. The coil looks to be wore, and I have herd the CDI is crap on these bikes.

It is a Diamo LS200...looks just like the roketa DB-07

200cc...motor numbers are ZS169FML

will these work?

the ebay page says it is a AC fired CDI, is mine AC or DC?

Did you get a wiring diagram with your bike? If so, the wiring diagram will tell you whether you have an AC, or DC, CDI unit. How many connectors does you current CDI unit contain?

looks just like the one in the photos of the ebay page, but black...looking around ebay...i see that they ahve both ac and dc cdis that look excatly the same...the connectors on the bike have 6 wires in them...so one connector..two wires, and the second connector is 4 wires...the cdi aslo say 511057 on the side of the black housing, 183 on the two wire plug connector, and is made by hecheng

You need to check the wiring diagram for your motorcycle to be sure you are getting the correct CDI unit. The 6-pin CDI units come in both flavors: AC, and DC. The DC CDI units are usually larger than the AC CDI units. I did not see a designation on the eBay ad you posted, but I would guess the eBay CDI unit is an AC CDI unit.

oh...if you look in the sellers other items, he sells the cdi seperatly, and he says its an AC fired one. I bought the bike used, so i do not have an wiring diagram. Would the diagram be for the bike or motor type?

The engines might have wiring diagrams, but I have only seen wiring diagrams for the complete motorcycles. Is your CDI unit small, with dimensions similar to the one shown in the eBay ad, or is your CDI unit larger?

Hopefully, owners of the 169FML engine will soon respond with expert advice. My Zong is a Yamaha clone, and employs an AC CDI unit. My Honda XR650L employs a DC CDI unit. However, I am unfamiliar with the 169FML engine. :roll:

mine is just slightly smaller than the one being sold in width..however in lenght it is the same...if it put the wrong cdi on my bike, will it damage my bike, or just not start? possibly damage the cdi? I am willing to buy both if a solution is not found.

let me know what you think of this...basically he is saying, start the bike, remove the battery and if it runs still, its ac fired...if it doesnts, then it is dc fired...also, he mentions size, and wires and show the diferences in the wiring diagrams...i could trace the wires and possibly find out.

If you install the wrong CDI unit, the CDI unit can be damaged.

The Roketa DB-07 employs an AC CDI unit. The DB-07, CDI unit appears to be the same as the Ebay CDI unit in your link.

It appears the eBay CDI unit will work for your bike, if your bike employs the same CDI unit as the Roketa DB-07. However, I hope WeldanGrind, or a Honda clone owner will drop by and confirm my suspicions.

That website is an excellent resource; if you follow the advice posted there you can determine whether you have an AC, or DC, CDI unit.

thanks spud, will do what website says and let you know what I come up with. Also...I think i might start a general knowldge manual for most chinese bikes. There are so many diferent types out there, and it is hard to determine which parts will work for which. With the knowledge of everyone here. I believe the manual won't be to hard to complie.

You're welcome, Rando.

Based upon the dimensions you listed for your CDI unit, I think you probably have an AC CDI unit. With your bike not running, and the ignition turned on, I suggest you unplug your CDI unit, and test to see if any of the wires leading to the CDI unit read 12 volts when referenced to ground. In particular, perform this test for the 2-plug connector. If you don't get a 12-volt reading, you probably have an AC CDI unit.

Then, if you wish, turn off the ignition, and plug the CDI unit back into the electrical system. Start the motorcycle, and unhook the positive lead from the battery. If the bike continues to run, you undoubtedly have an AC CDI unit.

Thank you for your willingness to gather, and share knowledge with others. Your generous attitude is consistent with the qualities we wish to foster at these forums.

ok, the cdi and coil will be in tomorrow morning, but cleaning the carb yesterday, i found a crack in the stock air boke, and fouind dirt in my carb bowl. I order a pod filter, but that will be a few more days to come in...so..im anxious about testing the new coil and cdi, but im thinking i better wait for a good filter to come. The crack in air box is between the filter and carb, so it is letting dirt right in there. I'll let ya know how it turns out.

I've a similar DB-05, and can confirm what's on my bike if it's easy to access. Where's this thing suppose to be?

I think you're wise to wait until you have a good air filter attached to your carburetor. Please keep us updated.
