GS Igniters

[Anonymous]

ok i might
sound silly i have a (1980 gs 850) with a weak spark problem,
ive tried a number of things
1. hotter plugs
2. coils
3. spark plug caps
4. pulse pick ups + backing plate
the plugs still foul really fast wondering if this could be the
the igniter unit .
is this the one under the right or left hand side cover.
worth a try anyhow.???

Ignitor innards

I too have a problem with a weak spark which fouls plugs and makes the bike run like a twin, then like a triple, then like a 4 etc.

Questions

Can an ignitor unit deteriorate or is it likely to fail completely (like a fuse does)?

Presumably there are different sizes / ratings of ignitor. I am trying to get a 79 GS750 (now with Wiseco 844 conversion) on the road and with the additional compression I assume that I may need a "bigger" ignitor. Is this in fact the case?

Previous posters have made reference to a DYNA S. What is it?

Lastly, what would be the recommended final solution? :--

Correct or repair the existing ignitor and ignition system OR

replace it a DYNA S thing OR

replace it with points which is what the bike had as original.

Thanks

re igniters

talked to my local bike wreckers he tells me some of the
igniter- units maybe tested and repaired if needed
as i priced a new unit in australia at $660.00 aud..

The points would be an option, but the Dyna S would be the way to go. You can go to www.dynaonline.com to view a wiring diagram for the setup. I think some guys mentioned earlier that they bought the dyna from dennis kirk.

I personally would not use points, as that is a step in the backwards direction...Are you absolutely sure it is an ignition problem? An Ignitor unit either works or it doesn't, it sends a low voltage signal to the coils to fire. If your sure it is ignition, i would trace wires first, making sure it gets a good connection, etc., Dyna's are pricey, especially from Kirk. :twisted:

Who can do the repairs to the igniters?

Thanks,

Ignitors can only be repaired if they can be opened. My 400s ignitor is a single sided dish and filled with epoxy so there's no way of getting at the parts inside of it. I've seen an 1150 that has had its ignitor modified (changed a capacitor) in order to change its timing. This was done by a dealer.

My 82 GK ignitor has a removable cover,and looks like everything was soldered by hand!!Even has normal sized transitors,resistors etc...looks like it could be repaired with a wiring diagram.Of course it may very well not be the original ignitor either...

The igniter on my 83 GS550L also has a removeable cover. I would like to get my hands on a schematic with values so it could be tested.
