83 gs650l ignition module problem

[miken55]

i have been informed that the dyna s does not fit my engine.
apparently there it has an odd geometry at the crank pick up acording to the dynatek tech help.
i have replaced the im with an ebay part and it did allow the bike to start and idle. however, when i give it any load (like shifting out of neutral) it starts to bog down, when i barely release the clutch at 2-3k rpms, the engine about stalls.
the carbs have a clean bill of health, there is fresh gas, but the spark is weak.
any suggestions?

regards,
mike

How many miles are on the bike? What all have you done to it? Is it all stock, slightly moded or full mod (pipes, pods, jets, ect.)? Is this a recent issue or have you been working on it for a while? What are your plugs gapped at? Compression test?

Good questions Dave!!! Now Have you had the air filter out while doing this or just put on pods or anything like that?Have you checked the stator? Also check the ohms at the coils.I think you will find your problem somwhere in those areas.Stick with us,we'll get it running!

I hope you can sort this out without a Dayna S... but for future refernce the is a thread covering a Dyna S install on a 82 GS 650E:

Hey, when i had that problem with my jeep it was because of the timing was off. If your bike is like mine, it has the pulse generator, with the mechanical advance, perhaps that has gotten stuck, or caught or something? Just a suggestion, and for the weak spark, check your connections to the coil, and make sure you are getting the full 12volts to the coils, and that all connections and wries are good.

just curious, what part did you get from ebay?
