CDI?  By  renegadestang (Read 1,143 times)

Capacitive discharge ignition.
The performance cdi will just advance your ignition slightly.

If the stock CDI has a RPM limiter then a CDI without one will yield more RPMs . A brand name CDI is often of better quality than a stock generic one even if it has no gain it may last longer

So bottom line is that if you are not having any real problems leave it alone. When I did finally have problems on my old bike I went with Orange CDI and the matching High Output Coil for better spark and starting in cold weather. Just make sure to verify if you have an AC or DC system as they are not interchangable.


The CDI is an invention of a certain Nicholi Tesla back in the 1890's.

My father worked for the Eltra Corporation who through their Prestolite division working with Chrysler came out with the first workable systems used in the automotive industry. Since my dad was an engineer with them even though in another division of the company we got a prototype system to install in the family car as part of the real world testing effort. The original Prestolite/Chrysler system would upgrade any Chrysler, GM or Ford ignition however GM and Ford chose to come out with their own much more costly variations rather than work with what Prestolite had developed. The system was much more reliable than breaker points and helped a lot in the winter when it was sub-zero outside.

this may explain it a little easier. You can see what it is here. all the descriptions other members have described are correct. It controls the spark. Here,you see it in the circuit ;D

So, when I'm operating at top speed / WOT, I sometimes get these momentary "misses". Lasts all of about 1/2 a second. Could the CDI have anything to do with this, or am I looking at something else?

I would check the connections at the coil . I would check all the ground connections .
