Thanks Larry. I'll sleep better now.When you try the stock map, if it idles fine straight up, we can only assume your bike doesn't like my map.
Balanced idle - 4 turns out on left side. ................... ................... but nothing when disconnecting, wobbling, reconnecting, tapping etc the right one.
Unlikely to be the map then. Did you buy the bike used?
Can you provide a screen grab of GuzziDiag connected showing RPM, temps and injection values with the current setup?What happens if you open the required air bleed to improve balance?
I did that Xlratr. Balance at 4000rpm was WAAAY out.
John, I always ignore the lambda values in GuzziDiag. They're up and down like house numbers, and when caught in a screen shot, mean nothing.
What I find interesting is that in the last two shots, with idle at around 1300, the pulse-width is 1700uS less with a CO at +15
Larry, what about the stepper? Any chance it might be jammed or non-functional?

...Adjusting the CO up, and getting a SMALLER pulse is all inside the ECU. No air leak or even a bad injector would cause that....
I think the ECUs primary goal at closed throttle is to maintain the target idle speed and it will do whatever is in its power to achieve that. That means adjusting timing and fuel. If there is some element in play like additional air coming from somewhere it will be all over the place trying to correct for it and those numbers we see in the pictures may just be a random view of a fluctuating picture. I can't help but get back to the fact that it's impossible to get the TBs balanced at both idle and high speed without introducing a lot more air on the left. To compensate for ... what?
I'm thinking maybe some 40mm pumpers? <running and ducking>
