Mt 07 a2 (35kw) o2 sensor with aftermarket exhaust

[Perjanni]

Hi! I just bought a mt 07 a2 version which is restricted to 35kw.

I also bought an arrow full system for it, and since its a2 restricted i cant get a tune for it or install a power commander. But i was wondering if i should plug the O2 sensor into the new system or remove it to make the bike run as well as possible. I heard that they often run thin from factory but people have different opinions on removing the O2 sensor or plugging it into the new system.

Answers are greatly appreciated as i dont have them myself, thanks!

Keep the O2 sensor plugged in to your new exhaust.

The O2 sensor only controls the fuelling during steady throttle cruise.
