Well, I dropped about 2oz of Seafoam in the tank and cleaned the K&N filter thoroghly (although it didn't appear to need it) and rode out and about for an hour or so. Later this afternoon I took er out again and WHOEEE, what a change!

Talk about a real difference! No stalling, Idles smooth as a baby's arse, and acceleration/performance is right back to what I had before all the trouble began. I'm thinkin cleaning the K&N helped, but adding the seafoam really helped the most.
end of problem....
