Mechanical advancer

I'm interested in learning so explain to me....How can these systems be a CDI type when they don't have this element?

You're focusing on a very specific design and not the operational principle of CDI itself. CDI can be implemented a number of ways. Regardless of how it's implemented a CDI always has the commonality that a capacitor is used to store a higher than conventional amount of energy and deliver it to the spark plug upon firing. This energy can take the form of a higher voltage (hotter) spark or a multi-strike spark. The capacitor for the H1 schematic in question is circled in red below.

For more information on CDI, consult wikipedia, your nearest library, or even the world wide web.

I would show you the capacitor in that schematic but you're not going to be here to see it anyway.

I'm interested in learning so explain to me. As mentioned earlier and as detailed in the link provided, a CDI should have both a pulse generating/trigger coil and an exciter/charge coil, but the GS/KZ ignition systems do not have a exciter/charge coil which charges the capacitor. How can these systems be a CDI type when they don't have this element?

You may continue to join the multitude that think it's a "CDI", but you will still be as wrong as they are.

I'm outta this thread.

It's quite sad that people are arguing that because their Suzuki doesn't have CDI, then the Kawasaki guys can't either. Jealous much?

You can continue to think I'm wrong that's alright. I know you don't know how CDI actually works so I don't mind if your lack of understanding challenges my understanding.

It's a shame you're bowing out of the thread on this account. I would show you the capacitor in that schematic but you're not going to be here to see it anyway.

That said, as others have said, this thread is about mechanical advancers on/for Suzuki. Kawasaki and CDI are irrelevant.

Yep enquiring minds would like to know... I have an 82 1100G and pretty sure the advance is in the spark box not a mechanical like my 1000's had. (hehe see what I did there ).

Having said that I'll try to take a look to be sure.

Your other (depending on the cost of a mechanical advance) option is to get the Dyna 2000 that has advance (as well as retard for turbo's, rev limiter & a bunch of other stuff) all in the same box.

I suspect you could also run something like this https://www.diyautotune.com and use the original trigger. I suspect there are other alternatives too.

The GS stock advance curve is pretty simple from any info I've seen posted about it... It's basically two steps.

A google search on "capacitor discharge ignition" turns up a lot of hits. One of the key elements seems to be the use of two coils triggered off the crank: a pulse generator coil (for triggering) and an exciter coil (to charge the capacitor in the CDI box). According to information I've found a CDI system of this type can use a separate ignition coil, which receives charge from the exciter coil. GS bikes don't use this type of ignition though, the signal generators only have the trigger coil, not a charge coil.

At any rate, this seems to be a pretty good read for anyone that's interested. I learned something from it. https://en.ppt-online.org/181450

Yes, we like our fun... just take a go at one of those advancers and let us know if it fits...we like happy endings.

Thank you great list.
Boys sure are a passionate group here...that's good!
My main goal for the 1100 G is to hear bang bang bang bang from the four cylinders....

Not to stir the pot, but....

I wonder what the "c.d." stands for on this KD device.? Off a 1970 f5 bighorn

edit...pic vanished, and resurfaced in later post.

I will just add one more statement here, then bow out of this thread.

The term "CDI" is Capacitive Discharge Ignition. Where is the "Capacitor" that is being discharged?

There isn't one. As shown in the mis-labeled diagram, they are using a signal generator (SG) to trigger some transistors to control the current through an ignition coil, which is an inductive transformer. The only capacitor that was ever in the system was the condensor that went with the mechanical points.

You may continue to join the multitude that think it's a "CDI", but you will still be as wrong as they are.

Yes, it's unfortunate that the diagram that I showed was also labeled "CDI", but as I mentioned, "... even the people that make replacement parts and those who sell on eBay are perpetuating the mistake, ..."

I'm outta this thread.

...but if it uses an ignition coil, it is NOT a "CDI"...

I'm sorry but that is completely incorrect information. Also if you are citing a wiring diagram labeled Early H1 CDI as also being wrong then there is a serious clash of data/information vs knowledge.

[Nessism]

Safe bet would be an advance unit from the below listed bikes. I'm not sure how this part differs from the earlier points equipped bikes though.

Regarding this whole "CDI" business is concerned, misuse of the term is epidemic it seems because guys on the KZ site do the same as newbies here. In the UK it's particularly common to denote an ignitor as a CDI, even among folk that know better.

Just looked it up, the Kawasaki system uses an ignition coil and a box of transistors to "fire" it, pretty much like our GSes. People mistakenly call that a "CDI", too, but if it uses an ignition coil, it is NOT a "CDI". Unfortunately, even the people that make replacement parts and those who sell on eBay are perpetuating the mistake, making it harder to cite an official PROPER source.

Yes “digital” ignition ....actually Kawasaki triples had CDI capacitor discharge ignitions .....

Well you jogged my memory....my Kawasaki f5 bighorn also had a cdi ignition....and used a surface gap spark plug. Like in this listing

Mechanical advance units were used with points and the first-generation electronic ignition systems from '80 through '82. The '83 bikes had the advance built in to the ignition module.
