Saw a slight indication of possible binding. Pure speculation at this point. In an EFI system the IAC controls idle. I saw the steps climb as it tried to maintain set calibration idle rpm. This effect could be binding slowing the engine or the mixture so bad it struggled to run. Both will cause an IAC step increase in the log I saw. Don't know exactly which caused it but generally the IAC has a drop in steps as the engine heats up. This is truly a unique set of problems with this bike. We won't really know until some of the possibles have been addressed, or at least ruled out. The hot restart in the vid also points to extra drag to turn the hot engine over. Binding, or weak battery or limiter slip are all possibles. I would do a full charge on the battery and do a load test to at least rule that out.That's the key krRob - all of a sudden he's having these issues. He found no metal in the oil filter or magnet so that's good nothing catastrophic so far. Those picks in the plunger could have been caused by sand / abrasive particles as well as metal particles I would think, with it moving up & down and rocking on the silica it ate a little hole thru the coating into the plunger - but I still don't see how more accurate oil pressure completely fixes this engine. Yes, this O/P needs to be remedied and eliminated as another hurdle on the way to finding the root cause but something else is going on as well. Need to pull spark plugs inspect,check compression, check engine for binding / rotational friction, and then continue with sensor replacement etc. as planned - sooner or later the root problem will be found.
