1983 GS1100 GK ignition questions

Hey guys and gals. Ive got questions about the Dyna S ignition upgrade. I've tried reading as mush as I could to find this answer without bugging for no reason, but it seems that there is no additional external module that goes to this system. It seems to me that the entire ignition system is enclosed under the side cover. Is this true? While looking at other Dynatek systems, I've noticed an external module that accompanies the pickups. (IE - the Dyna 2000 system)

So without further gum bumping, my questions are as follows:

1)does the Dyna S system come fully enclosed in the single form-factor package that it appears to come in, or am I only seeing the pickup?

2)is there a programmable Dyna system available for my bike (1983 GS1100 GK)

3)with the Dyna S system, i wont be needing my '"iffy" stock ingitor?

4)my spark is blue- bike drags under load ( 60mph with throttle finessing)- my carbs I rebuilt and they work like a champ on my friend's GS 1100E with after market K&N dual port air cleaners- Should i rejet anyway? or could there be another problem I'm missing?

any and all questions answered will be most graciously accepted!
 
Dyna S is a set-up for eliminating just the points and the condensers on '79 and older bikes. It won't work on your bike at all. Try cleaning all of the electrical connections especially the grounds. The stock ignition on these bikes is plenty strong enough for stock set-ups if the parts are in good condition. One other thing is to unscrew the spark plug caps from the wires and cut off about a 1/4 of an inch off of the wire and screw the cap back on, this gives it a better connection also.

No, they are stock jets. Im not under the idea that I'll need to buy a stock jetting kit with the pilot jets as the idle is fine. However, under a load, it bogs pretty easy. It would seem like a fuel/air ratio problem. So should I buy a 12 pc kit with the assortment of jet sizes? Also,in anticipation of this problem, I interconnected the air filters with a "T" into the valve cover blow-by port to maintain as best a natural air flow as the sytem originally was designed. With or without the air filters connected together, or connected to this valve cover port, it makes no difference. It still bogs down under a load. The coils provide a nice hot blue spark at each plug ( new and gapped plugs), the fuel flows nicely from the petcock and is unobstructed. So what Dyna can I use for my bike? As I've heard so many great things about Dyna. Also, the stator has 2 live legs instead of 3, however with the kill swich I put on my headlight, I'm going to say with no doubts that 66% of nominal current should be enough to run the ignition. The contacts I've already gone thru and cleaned and replaced if needed.
 
I believe that Dyna S will work on a GK, only you will have to get a mechanical advance unit off an early model bike. That said, I seriously doubt this is the problem with your bike. These GS bikes are very sensitive to the air/fuel mixture and since you apparently don't have the stock airbox, that is most likely the issue.

I suggest you chase down a stock airbox and then make sure the jets are stock as well. The 1100E carbs use different air jets so I'm not sure if that will be a problem or not since that part is not replaceable.
 
Is there some resource that might be of assistance in selecting the appropriate jetting size for the air cleaners I've installed? Or am I going to need to Roshambo with the carbs? The Pilot jet and the main jet are both replacable on my carbs. They are the stock carbs for the bike.

The resource is here in the archives. Learn to use the Advanced Search feature, use Titles Only, and then dig though the literally hundreds of threads about rejetting carbs. I can tell you right now that getting a proper airbox is the easiest way to fix the bike. I have an airbox off a 1000GL, which I think is almost identical to yours, that you can have for cheap. If you get frustrated with the rejetting drop me a note.
 
If you go with the Dyna S I have an extra mechanical advance.
The Dyna 2000 and 4000 do not require a mechanical advance. The 2000 is more than what you need and the 4000 is mostly for drag/race bikes.
 
So if I go with the Dyna S, how does it get hooked up? In the forums, I've seen a question about an 83 GS1100G as it pertained to a Dyna S upgrade, but there was no answer posted. Here is the posting. It's at the top.

http://www.thegsresources.com/q_a/gs_qa_electrical.htm

How much does a Mech Adv go for even? Not having one on my bike, I don't know what to look for nor what they look like.
 
As for the rejetting, I've seen other resources giving the best match for various K&N filter upgrades, but I've not seen them here. I'll make that my next few hours of research it seems.. lol.. I'd rather have the K&Ns for multiple reasons, besides their MUCH better aesthetic value! lol
 
After looking further into the Dynatek website. I'm not tyring to debunk any of the information from anyone on this website, however, I saw this the kit for my bike:

https://dynacart.jetkit.com/Shoppin...aonline.com/skins/products/sportbikes/dyna_s/

Now, if this is the one I need ( as per Dynatek), they say nothing about needing additional parts. I'll be calling them Monday. As I attempt this ressurection, I've heard different terms and nomenclature that I don't know. While researching the jetting/rejetting threads, I've run across people referring to "clip" settings in the carb rejetting process as it pertained to the needle valve. I hadn't noticed any potential "clip" settings when I rebuilt the carbs. Care to enlighten an ignorant man? Also, Can anyone tell me where to get some reletively inexpensive boots for the carbs? ( between carbs and jugs)

The DS3-2 unit shows for the 1100 but they mean the 1100E, chain drive 16V engine.

The "clip" is on the carb needle - you lower or raise the clip to lower or raise the needle.

Your bike does not have a mechanical advance unit, the spark advance is built into the ignitor. There are other GS bikes that are the same way such as the '82+ 850. People have installed a Dyna S in their bikes by getting a mechanical advance unit from an earlier bike and then bolting the Dyna S in. The Dyna S costs about $120 and is a good unit so most people don't want to dump the money into a Dyna 2000. If you call Dynatek they may not know that you can install the S into your bike so they will try to upsell you. The advance units for the 850 and 1000 are all the same so it should fit your bike as well since the 1100G came from the 1000G.

Partshark.com is the cheapest place to get parts

You also may need to shim the ign cover out 1/4" for clearance
 
Ooops, my bad.... I didn't think you could use an "S" on a bike that had an igniter style ignition on it.
 
Get the Dyna S and Dynojet kit.
I'll get you the crank bolt, bolt end and the advance.
Boom, you're in business.
 
BOOM! Back from the bar! so let me get this straight...? How much is a good mech advance unit? new? used? And by that measure, wouldn't is be better to get to just get a Dyna (upsold) 2000 unit instead of buying the new/used mechanical adv which is an older generation of technology anyway? Can't you program the 2K model? If not, the next model up should be programmable yes? If that be the case, why wouldn't I spring for the extra cash to be able to make those changes pn the whim? I'm not so opposed to spending the money for functionm, but I'd just rather not spend cash without reasoning. Opinions?
 
If you'd "rather not spend cash without reasoning", fix the real problem which is the carburation, not the ignition. Get the jet kit since you are going to need that regardless. Dump the money into the ignition afterwords if the problem persists. The factory ignition parts are high quality and rarely fail. In fact, you can pick up a used ignitor from an 850/1100 for far less money than even a Dyna S.
 
The Dyna 2000 is programable. You can set the advance and I do believe a rev limiter.
The mechanical advance will advance the motor the same as the 2000 which is all you need for the street.
 
Gonna break down and put a 2000 on the E, but for general use, the S is all you need.
