Oh yea, I forgot to ask, how do you test the coils????



swap it out with a known good one. Yeah right. Which one is bad then in your case? Not like you can swap the coils with each other and move the issue left/right.

Coil failures will mimic dirty idle circuits too. When they do, the bike shuts off. No way to really discern which cylinder lost spark.

So a known good coil would need to be test run in both the left and right sides.

Bad procom cdi will mimic one of those bad coils that mimic dirty idle circuits.

There is a resistance ohms check you can do, but you can't perform that test while the coil is under load. the dinqa wrote once of a device that would test a coil under load. dern might expensive that lectric gadget is...
