Hi all, got this capture this week from a Honda VTR1000 which i had just fitted 2 new genuine coils to as the old coils had failed and i was curious about the waveform it generated, Both cylinders are the same and primaries obviousley follow. All are included in the psdata file if you want to see them.

I am looking to understand why this waveform woudl look like it does. This is a CDI ignition system, wasted spark and carb'd fuel delivery. Carbs have just been gone through and bike runs fine so no concerns other than this was not what i was expecting to see 

Although i have seen this before with other CDI ignitions like this Honda XR70 and it has the same characteristics.

My question is how can i analyse theese waveforms like i would a "regular" secondary capture to see burn time and coil oscillations etc etc

Thanks in advance for any input

Cool thanks Anthony, I will when I get more time have a play with some cdi systems and see if I can get a better idea of how these may be analyzed and post somewhere here, for future reference.
