CDI Unit Circuit Diagram

[pchannon]

Hi all,

I'm looking the circuit diagram for the CDI unit for a 1984 Suzuki GS550E.

Would the CDI unit of a GS850 or GS1000 fit on the GS550?
If so, are they any conversations that must be done?

Thanks.

You might want to try the search function since there have been two long threads here on this topic recently. One guy adapted a late model 750 ignitor (not CDI) to his 550, and another guy cracked open his ignitor and repaired it by replacing some burned transistors.

BTW, the early ignitors won't work on your bike because they had a mechanical spark advance but your bike as the advance built into the ignitor itself.
