You could just get a DC CG150 CDI, then change the two prong mail plug on the bike to rectangle.
I have come across a few adverts that have CG = rectangle and CB = rounded plugs.
I would assume the differences to be the preset curves? Due to the CG being a lower revving design?
I've got no idea what is different - could be how it sees the engine etcQuote:

I could try find a DC unit etc and I've seen leads to convert but the leads come with the fancy changeable CDI
So, once again: are you currently in China or in Kiwiland? :eek2:
I saw this screwdriver-adjustable CDIs, both AC and DC, on "Aliexpress".
I'm in China - Chengdu
And no one among locals can help you with your problem? :confused1:
Somehow, I expected that in every Chinese town you can find repair shop within walking distance, especially for domestic, more or less fancy cabbage-turnip-zucchini bikes...
Last owner tried and failed as the mechanics can't think outside the squareQuote:

As you can see both the same model best I know - would that solve it? I suspect the seller of the performance CDI would just supply to suit this set up CDI but can't confirm details of its generic or not

That CDI is for "dual" (双) sparkplug model http://item.taobao.com/item.htm?id=520598680292 It states clear 必须帶电瓶 MUST use batteryQuote:

[CDI]
Most universal one is based from E-start Kymco (rectangular one) & kick ONLY that based from CG125M (花猫/幸福)
Other crazy shit :[Piaggio] dual boss (双凸台) on rotor / [Zongshen] dual spark plug / [Jialing] Tons AC source coil in their stator = needs their own CDI
That really throws a spanner in the works Huh
Dual spark? Sparks each revolution? Or 2 spark plugs?
One other question
DC CDI should it be able to run without a battery? I can change the phases to either run with or without a battery
If you know let me know
ALL depends on the CDI design (some works on dirty input while some don't) ... Use a cap "store some energy / smooth the waveform" http://www.motorfans.com.cn/bbs/view...originator=yes IS OK in theory (will the cap burst in long term, nobody guarantees) ...Quote:

The CDI gets a consistent supply of 14-15v DC off the R/R that it stores as it’s a capacitor. It gets a signal from the trigger direct off the stator with each rotation, the curve is a preconfigured curve for releasing the spark to the coil. A CB climbs faster in RPM then a CG so the firing would be different. It is all integral, the rate of current, and the firing increases with rpm.Quote:

There is an electromechanical firing order to the coil between the trigger and then when the CDI actually fires the coil. That’s a curve as in a run X over Y, its linear simply put a rise over a run. Changing a curve is about altering increasing or decreasing, timing.
The CDI gets a DC current from the stator? But stator is all AC
There are 2 15v AC out puts connected and the trigger AC that's blue
On the bike loom the 2 phases of AC are yellow - so I would think its both the same? Only difference I can make it do is run with or without a battery
Would think only running with a battery would be a cleaner DC to CDI
But being able to run without a battery is easier if the battery is flat
LOL yes the AC stator feeds (2) get rectified to (1)DC output in the R/R, that feeds to the CDI in yours it is supposed to come off the R/R, in an AC system the High Voltage feed you got shocked with connects direct to the CDI, the RR in those only charges the battery.Quote:

The output for the trigger is or should be low voltage AC like 1-2volts and direct off the stator to the CDI. The rest is all connected to the battery and so is all your other lines, lights, horn....down the loom.
Ok so actually there's no diodes in the RR
It uses the 2 highs of the wave to get some flat line that's like DC not such a true DC then
Yes single wire to 2 pin plug is the very low voltage 1v at most and tests fine - that's the trigger wire to CDI Blue with white
High voltage AC line not connected cause that's the AC CDI feed and not needed in this case as its s DC CDI
Keep in mind DC as current only flows in one direction (+), the RR uses diodes to alter AC (-)(+) alternating waves into a DC current, I found this link from Tufts Univ, that offers a good explanation.Quote:

Bike is a runner! Special CDI and it only needs a extra + power source connecting!
Revs ok!
I don't know if the CDI is made to suit my Frankenstein bike or if it's a generic CDI of another model but it's working!
Idling and engine starting with a kicks tarter?
Don't know or care about kick start
Ok rode to the local market and bought a common DC CDI and runs the bike - seems they are not so complex at all - some reason the Shineray one didn't work yet common DC does and my expensive programmed one also
