Hey man - saw you had shot me a Visitor message - replying back to you here.
when you say it has no spark, are you testing at the plugs with a tester, or grounding a plug and looking for spark?
2 ICM's hopefully eliminates that - unless you had 2 bad ICM's.
I would doubt you have 2 bad coils if you're not getting spark at all 4 plugs.
there are 2-3 easy points of failure that could keep the ICM from getting power.
The Stop/Run switch on the right handlebar is prone to having the solder joints crack and fail. If that is the case, the ICM doesn't get 12v+. The fuse for the ICM is the same as the starter - and you say the starter is turning the motor over, so that fuse is good. Turn your key on, bump the starter to make sure it turns. Then with a volt meter, check the Black/white wire at the ICM plug - that should be your 12V+ feed for the ICM. If you're not getting 12V there, pull your handlebar switch housing apart and check the wiring there. If that is all good, then you'll have to trace the wiring through the harness. If you are getting 12V at the ICM - then there's likely a grounding issue somewhere.
check that first then we'll go from there
Other things to check - connection to the pulse generator, connection to the kickstand switch, connections @ the clutch switch, chassis/clutch switch Diode, neutral switch.
