I'm assuming the 'standard' figure is fairly universal for these bikes and not unique. If that's the case would I be right in thinking that I need to lower her CO mixture to nearer 25?
In case it's relevant the bikes have both had the same mods: metal mule (scorpion) exhausts, K&N air filters.
Any light you can shed would be greatly appreciated.....

Most 07 models with O2 sensor are around -5 to +5 on the CO, 25 would be a better setting for a 07 model.
