This is what I was looking for! Thanks. Now the question….is a tune required with the 10R if the pre-chamber/cat is removed? Of course I know that it’s recommended in order to etch out additional performance but required as in the sense that in the long run it causes engine/valve damage if not addressed with a fuel remapping due to leaner conditions.LoL! I was thinking same thing but I don't own a gen 5 and @SkyDork seems to know a lot more than me. Did some more digging and looking at the service manual for the 2016 zx10r it shows the honeycomb type catalyst in the premuffler/prechamber. So that would put the O2 sensor before the Catalyst.

In this post. Gen 5: 2016-2020 - ZX10R & some general questions the answer is that a tune isn’t required but I just wanted a confirmation from those who are familiar with this bike.
Thanks in advance.
