Posted October 15, 20222 yr I am having some trouble re-working a yamaha cdi for a custom application. Would you possibly be able to tell me which wires go where for a typical yamaha 8 pin CDI for a 2 stroke? Nothing I try gives any spark. Any help would be greatly appreciated [url=https://postimg.cc/5QBSjrWy][img]https://i.postimg.cc/5QBSjrWy/ew.jpg[/img][/url] [url=https://postimg.cc/G9GQM4TR][img]https://i.postimg.cc/G9GQM4TR/external-content-duckduckgo.jpg[/img][/url]
October 18, 20222 yr Hi there, It would be helpful to know what the typical 8 pin CDI was originally intended for and then read/view the circuit diagram for that bike to be sure. As your two photos supplied, one is for a pin out of a 125Z, and the other has different pin outs for a different fitting. Having said that, you're confident you are getting a voltage/signal from your generator and pulse circuit without the CDI being connected? If you are, then presumably you're having trouble getting the CDI to produce the spark, is that right? your links don't work so well, so here they are... https://postimg.cc/5QBSjrWy https://postimg.cc/G9GQM4TR You may have already seen it, but I found a useful video explaining about an 8 pin CDI which may be of use to you. https://www.youtube.com/watch?v=m6RCTWhIrTk Edited October 18, 20222 yr by NE0
