Mechanical advancer

[Guest]

For Dyna upgrade on a 1983 GS 1100 G

What models can donate the correct advancer?

GS 850 through GS 1000?

How about 750's

For sure, the 79 and 80 850s, I don't know if the later 850s went to an integrated electronic advancer. However, not sure about the curve being suitable. Some fiddling may be required with springs. That's apart from the nose of the crank being the same size, of course.

My wife's '82 850L still has a mechanical advancer. Not sure if the electronic advance started mid-'82 or not, but it was definitely there for '83.

The parts fiches show two different mechanical advancers on the 850 and up engines that use one. The odd one is for the chain drive 1000 and 1100 E's. Different crank end ? Different springs?

I'm starting to think the GS 1100 G is the odd sister out when it comes to the installation of the Dyna system.

The 850's and 1000's prior to 82? had points and of course the governor advancer .Than when you get into the 1100 E's you've moved on to the modern CDI systems. Different kettle of fish.

Different part #'s on the 850's give me pause as to which which advancer to try and find.

Springs and progression of the advance could present a tricky combination.

Has anyone out there a Dyna on a 82/83 1100 G and what advancer did they use?

If you look at the parts fiche for the 83 gs1100E, you see it's got the mechanical advancer and the simple ignitor to match . But the advancer is different from the unit found on the 80 thru 82 850 and 1000 G's for some reason

You better break out another kettle for some more fish.

NONE of the GS bikes had points, starting with the '80 models. The last points (in the US market, at least) were on the '79 models.

Also, NONE of the GS bikes (or any other motorcycle) came from the factory with a "CDI" ignition system. Yes, it was electronic, but not "CDI".

Yes,indeedy. it might seem pedantic but the loose nomenclature "CDI" will lead you into a real hole if you ever start seriously trying to figure out your ignition... Different animals....almost like chain and shaft drive.

[J Mac]

Yes “digital” ignition ....actually Kawasaki triples had CDI capacitor discharge ignitions .....
I believe there are listing for mechanical advance governed units listed for 80/81 GS’s not sure what part of the world.
I believe they would have been used only with a points set up but perhaps not?
Ironically they are needed for the base Dynatek system.
The question is what advance governed unit will fit and work with the Dyna system on a GS 1100 G?

[Steve]

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.

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

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.

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.

...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.

[Steve]

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.
