Motorcycle primary ignition voltage & current trace

Hi guys.

I have an MV that runs rough, like a missfire.

I am wondering if you can help me to understand the trace I have taken? The voltage spikes at the end of the burn time and I have not seen this on anything I have tested previously, and looks wrong.

Thanks very much

Is that all you notice ?

Twin cylinder ?

Secondary ?

What about the current amplitudes, single COP, cassette type ?

1000cc bike is more likely to be a 4pot.
Coils are 'probably' double ended wasted spark
