Mechanical advancer

[J Mac]

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.

..., I don't know if the later 850s went to an integrated electronic advancer. ...

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?

tks

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

[Steve]

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? :-k

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.

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.

 

[J Mac]

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....

 

[tom203]

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.

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

 

[salty_monk]

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.
