Once I accessed the CO mode in the bike's computer menu (you hold down this button, then that, then another on the instrument cluster - details are somewhere in this thread) it was set on minus 4 and I changed to a plus 2 or plus 3. That was 18K miles ago and bike runs strong and I've had no issues. It's never made any sense to me to pay for a programmer when my bike runs great without one!


So you just assumed that was a good mix? How do you know if your mix is good? Just listen to the bike and see how it pulls?
