Idle drop was good, could have been leaner on the bottom probably, but when it dropped all the way down, it didn't want to stay running until I raised the idle. Thing wanted to die instantly after coming off the throttle when it was a little rich. Might be plug too, or exhaust seals, or perhaps clutch bearings -- just really haven't investigated at all as I had to go drive my electric car for the next main.

I'm betting that my low end needle and idle screw need some love'n as they're still set at the same place they were on the first race tune on the first time I tuned the motor after finishing break-in. My guess is that it has run in a little and I should have updated the tune by this time.
I can say with the Idle gap set properly and the LSN set to get your idle correct,and a little tweak on the HSN for performance( all of this from Ron, Thanks) these things never flame out. Atleast with mine I have had no flames in several Amains. I think I do run my low end just a hair lean but it werks fine and most importantly never lets me down in the mains. 10 min run times, mad low and top end, reliability = another B5 in my shoppimg cart
