1980 GS550E Electronic ignition .... issue

[uk gs nut]

I would think the problem is not in ignition if cyl 3 is firing ok. Have you tried swapping plug caps from 2-3 to see if the problem moves to 3. Only asking as there is resisters inside the caps. You could also just bear the plug lead ends and wind them to the top of spark plugs to eliminate the caps. Finally my son's 1978 GS550 had KD ignition Pryor to Dyna.

Plugs ok, ht leads ok, caps ok, coils ok.
Iv swapped all about. The above is true .

What dynamic do I get ?
Kokasan or the Dyno ? Ds31 or 2 ?

I am sure I had an answer to this but lost it.
On mobile see abroad so very hard

Can you get a compression test on #2. The Dutch people are very help full, perhaps you could find a local workshop/garage to borrow a tester.

[uk gs nut]

Dyna S DS3-1 FOR KD ignition. Get a compression test before spending more money.

[ukjules]

Compression ok !
I have just looked on dyna web.
Nippon densi ds3-2 77-81 bikes
Nippon kikusan ds3-1 77-78

Are you sure my 1980 would need a ds3-1 ?

[uk gs nut]

I would take out the mechanical advance unit and see if there are any markings on it. KD or ND, make a mark on the baseplate to help refit in correct place. If you have spark on 2-3 and compression I would look at #2 carb, is the diaphragm ok and the jets. I think you have CV carbs if I recollect from your older posts. As I said before don't spend money uneeded, spark + compression + fuel with #3 running #2 SHOULD run

[ukjules]

I need a electrical ignition unit as my one is rubbish. It won't be wasted money.
Newtronic has caused me so many issues. Pirahna were good.
I still need to know which dyna but will have to go by there site.
Dyna ds3-2.
Unless you or anyone else has a good reason not too. I understand it is not what you said.

Issue:
I can't strip carbs here. Plug soaked in fuel anyway.
I'll look at atu but seemed ok.
I'll look atvacuum screws on inlet rubbers.
I'll check mixture setting on 2

I agree 2 should run but it does not.
It was sudden on a very hot day this happened.

[ukjules]

Mornings work so far:

Plugs cleaned and set.
Inlet vacuum screws 're tightened ok
Mixture checked. Nothing way out. 2-2 1/4 all of em and plugs ok

Same issue.
Plug 2 has spark when test, plug on top engine.
Fuel I am sure on plug, and was when drove 5m yest.

I'll pull atu soon. Need tools / 19mm spanner.

What could it be ?

Pickups ? (I have my old ones being sent over) they fit.
Ignition system ( ds3-2 soon to be ordered)
What else ?

[ukjules]

Tools purchased. Inc multimeter.

Pulled atu and it seems ok. Springs work fine .
As I see it is either the
Pickup or the electronic box that sits before the coils.

Still same , plug 3 does nothing.

Dr3-2 ordered.
Old pickups being sent a over and my spare regulater.

Anything I can do while I wait for these bits ?
And being sent n Amsterdam I mean on the bike !

[uk gs nut]

Jules I have a full points ignition with atu mount screws everything you need to return back to stock. I can post them to you if you want

[ukjules]

Hi, thanks for offer and I might take that up.
Let me think of iv dotted the I's.
Is there anythibbg else this mad issue can be.

What price do you want ?
I can pvt later if wish . Think you can on here.

[uk gs nut]

Just pay postage that will be fine. You can PayPal later. The points plate is KD. Just send me a message for address. Are you on your own or with friends.

[ukjules]

Alone.
The thing is we have understood that my bike had dyna not kysosan.
(Spelling wrong as simply cannot remember the names)

So will those points work in my bike when it would not have had them ?

[uk gs nut]

Yes it is from a gs550, kokosan. It is exactly as csml website shows for your bike. You say you have swapped coils from 1-4 and 2-3 and the fault stays on the same cylinder ?. That is confusing as it doesn't sound like an ignition fault. Have you not got European rescue and recovery on your insurance ?. Myself I would try to limp home or at least get to the tunnel to get onto UK soil. Good luck and let me know if you want these parts, I am not at work tomorrow so could post them.

[ukjules]

Kokosan = 77-78
Dyna = 78-81 my bike 1980.
This is from the dyna website. Ds3-2 is what they say I need.

I have to go with what dyna say.
If they are wrong I can return it. How it reveals to be wrong
I have no idea.

Cmsl doesn't really have a 1980 e bike ?
Unlike kawadakis I can't get the right part number.

It's so confusing . I so wish someone with the same bike would answer .


I thank you for kind offer but I don't think they are right.
I have no idea if the are interchangeable, if you can , can't , whatever.

I'll stick to my Kawasaki after this.
It's just too confusing doing the simplest tasks you do on other bikes.
