Hi Franke,

Unsure about the waveforms we dont see many of this model here but there are a few things that i have found that can cause the popping in the inlet particularly when hot. Given the apparent late ignition timing on only the one cylinder i would start with the crank sensor for the cylinder giving the fault, according to the manual/ wiring diagram there are 2 sensors one for each cylinder and its not uncommon for them to fail or get bad signals when they get hot. Could be the cause of the 1 cylinder having issues. Also depending on milage and history of bike either rich or lean carburation can give similar popping in inlet manifold. Worn carb, anyhting above 25000 miles is common to find symptoms from wear particularly on angled mounted carbs? or blocked carb if having been sat for a period of say 3 months or more.
