CDI Module for Honda Motorcycle CB250 Nighthawk 234 1991-2016

Owner of a 2004 Honda rebel 250cmx. Had no spark condition on my bike. Checked stator, ignition coils, spark plugs, voltage distributor, checked all the wires, etc. Everything was pointing towards a bad CDI unit. Ordered exact match from eBay, didn't work. Used this CDI and it started right up! I don't remember if I have reversed 2 wires, but do it if your bike doesn't start.

ZER0 stars. I ordered 3 of these, and NONE of them worked. I purchased a used CDI, and my bike fired right up. also, I was only able to return 2 of the 3 defective CDIs. no spark on your bike? DO NOT try to solve the problem here.

The wires were opposite polarity to the plug. You’ll need a meter, since the wires are electrically opposite of what you expect. Unfortunately you’ll have to do some rewriting because the plug only goes in one way. Just be aware!!

As others said reverse the 2 pin connector 01 Honda rebel 250. But it started up great. Also slightly smaller than original so I electrical taped it to the existing harness

4 stars because you need to reverse the wires in the 2 pin plug REVERSE THE WIRE in the 2 PIN PLUG!! I didn’t see this till I ordered from another site thinking this was junk Well guess what The CDI came from the other site $13 more and is the exact!! Same name, box, and all! So I was looking to return to AMAZON and read a couple posts TA-DA!

bought this for my 91 cb250 and it would receive power to the cdi but would not transmit the power through the cdi. bought an OEM version and solved the problem. just spend the $85, save your time.

Worked great for 02 rebel 250. Bike was losing spark intermittently and stranding me. needed abnormal amount of choke at times (weak spark) But never would act up when trouble shooting at the shop. The wire location on 2 pin plug (cdi plug) needs to be reversed on bike harness to work. (Credit to previous review) Rode out tank and a half with new ignition before posting this review. Bike has way more pep and almost never needs choke now. Part was so inexpensive I have cash left to buy new bars.

It works great! Loved the pigtail it comes with. Made it easy to wire it for my 86 CMX250.

This unit was dead. I know this because I replaced it with a unit from Rick's and the bike fired right up. Even the original unit could get it running sporadically. Stay away from this.

La primera vez conecté el CDI tal cual viene y no funcionó, no encendía la motocicleta. El plug-in de 2 cables viene cambiada su posición. Una vez hecho esto, la moto funcionó correctamente. Definitely the CDI works. The plug-in with two cables are reversed. You only need to change the position and that's it.

This earlier model CDI unit had two ignition coil supplies not one in the wiring harness for these motorcycles later CDI units only have one ignition coil supply from the CDI unit.

Exactly as described works perfectly

Purchased for a 1999 Honda rebel, this cdi unit was failed right out of the box. Part is no good
