I've changed the rpm to 920, as suggested by KB, and the afr to 14from 1000 rpm; problems solved. thanks.

My exhausts (ex streetbob originals) drilled open, do the SE (shortcut) imitation on the selected supertuner map. When I open the throttle a bit I can hear a squeeking sound in my right exhaust (the one with the valve). Maybe the "drilled open hole" has sharp edges causing the squeeking, or maybe the valve (since opened by supertuner)squeeks (no mise nor coalmine canaries inserted). Anyone ever noticed similar?
