Whats going on?

I built this gasket for a Moto Guzzi as a test bed to see if an embedded igniter with four paired electrodes would work as a perimeter ignition.
I knew that I would have a timing problem but I am back firing through the exhaust at on/off throttle. The Lambda numbers are ~19. I took 3 of the plugs off line and I am just firing one of the embedded igniter's, and it still is backfiring at on/off throttle with a Lambda of ~16. I took the same plug wire and put it back to the original plug and all is well, with a Lambda of 14.

I will deal with the timing problem later, now I would just like to get one electrode working

I don't know anything but the people that do.

Personally I would trust the meters and add extra fuel with the 4 electrodes hooked up, if it get better then you know it was an over burn of the existing fuel......if not then it can be an ignitor/ignition issue.

just my .02 of observation.
