Had this CDI running on my '04 644 and now on an '06 628. Bit confused on what is compatible and what the differences are? Ignition curves? Ignition advance at low revs and start up?
An '04 644 has a 80039031200 as standard figment.
An '05/6/7 has a 820.39.031.000
I'm running a FC stator and flywheel btw
What are the differences and what effects if any in overall power and starting?:unsure:
Many thanks in advance
