It has a loncin cbt 250 engine, it had the stator, impulse sender replaced, but I suspect someone put the wrong Cdi in it. It has two coils and two wires coming out of the CSI to the coils. Only one coil sparks, if I change the wires over the other coil sparks. It's a six pin cdi. Are the Cdi different for a single coil
How do I write a thread? Stupid question I know ��
Any pictures? What's the stamped letter on that CDI?

Typical chinese 233 twin is 90s CA250 (Rebel) copies
Wrong CDI (cap inside CDI is smaller, can't output enough juice ...) / stator (designed for 2 cdi CB125T) may jammed in

Thanks for the reply HB, I'm thinking the last one the cbt125 is my answer. I'll go take a pic, the letters on it are XW or it could MX, no numbers
Attachment 18620Sorry the CM125 looks like the answer, here is a photo of what is in it now. Only one coil sparks with this set up, a weak spark too.

Attachment 18622Attachment 18622You are amazing, no one I speak to here in Australia seems to know about the Cdi with two feeds for two coils. How do think I can get my hands on the correct CDI. I want to get one new coil too. Photos show it is 233 and the serial number too. Thanks for your helpQuote:

Stock wire hardness obviously for 2 CDI
360 crank -2 wire

Even it's a 360 crank, there's a streetwise tirck from bike mechanic: Use jumper wire fed the splitted pluser singal to 2 idenctical "generic" DC-CDI https://item.taobao.com/item.htm?id=9597038946 (Old bike ALWAYS f***ed CDI's source power coil in stator)
Proper stuff exists but costs time to order...
It definitely has a two wire pulse sender, one blue white stripe, one greenQuote:

Guys from http://www.hondatwins.net/forums/forum.php | http://www.hondarebelforum.com/ may have more clues.
The harness and coils are set up as in the CMX250CD schematics, with two b/y wires coming out of the CDI, one feeding each coil. Not one wire feeding both coils. So it looks like I need a CDI to suit the CMX 250 CD. Now I just need to find one.Quote:

Thanks for all your help. The new stator is putting out 33v AC, the old one was 38v AC, I've put in a new impulse sender as the old one was damaged. I've ordered two new coils, ex China, and I will probably order a Chinese 6 pin CDI AC and link the two coil feeds to the one output from the CDI. Someone told me that 33v AC is too low to fire up the CDI. What's your thoughts on 33v output whilst cranking. I'm determined to get this quad going, but it is doing my head in.Quote:

So does that mean, use a DC - CDI, replace the red/black wire from magneto to the CDI, with the black wire from the start key (12v). All other wires remain same.Quote:
