That’s a very inconsistent spark.

Throw your scope on the negative side of the primary of the coil supplying that spark.

I will do that. I will also check voltage drop between battery + and coil positive supply.
New spark plugs and eBay coils are on their way too.
Voltage drop between battery- and chassis is 0.014V so the main ground seems ok. Even though I have improved the ecu ground (voltage drop from 0.25v went to 0.07v with extra wiring) I would like to check all other grounding points, but I can't locate any. The only one i have found is behind the instruments cluster (S2 half fairing version). There are two grounding "spiders" near the ecu which I have cleaned but I was not able to locate and follow the wire that actually goes to chassis. Any other known grounding points?
