Changes to the air intake are much more significant than exhaust/silencer mods when it comes to fuelling.

BTW, changing the CO setting will only affect the A/F ration at tiny throttle openings <2% and really won't make any significant difference to how the bikes feels/runs.
Thanks Pleiades,
Do that apply even running without db killers? I have considered running a K&N filter also to have a little better low end register.

Did you experience any Improvements With Akrapovic only?
