Well, arguing aside, it's done. It was indeed the evap system and after 120 miles today the plugs look perfect and the bike runs as it always did. Vibes are also almost gone. Whatever that was the fuel problem must have amplified it.

Seems greybeard nailed it long ago when he mentioned the cannisters being full due to overfilling the tank. But i couldn't find a way to empty them and apparenty plugging off the nipples wasn't enough to remove it from play. Googling it i found lots of info on this malady especially with cars where it's apparently very common. Once i ran it for about 70 miles this week with the vent hose detached apparently they finally dried up and all is back to normal even with my shims back on the needles.
