That's not surprising to me...I set my pilot mixture screws perfectly with two Colortunes.
Then I had to change their settings, to get it right!
I get tired of explaining why it's important to understand that the best static A/F ratio at idle, set by the idle air screw position is not necessarily the best placement for the idle air screw because it ignores the screw position's effect on early throttle engagement, which is a dynamic interaction, so the screw position has to be set with a dynamic method that explores the screw position's effect as the secondary fuel component combines with the idle air screw setting as the throttle is engaged.
If you can do this with a colortune, I don't see a problem, but plenty of people complain about how their bike idles fine, but has a stumble when they accelerate. Their problem, I have found in some cases, is they don't set their idle air screw position dynamically.
