Hi, Just been starring at my bike for the last 1/2 hour wondering what is the easiest way to refit the o2 sensor!

About 2 years ago I installed a PC V, DNA stage 1 and 2, Akrapovic single can and an O2 eliminator.

I think I have read that the O2 eliminators do not work therefore I bought a dynojet O2 optimizer from the nec bike show last week.

When I had a custom map made the guy removed the O2 sensor as it was now replaced by the O2 eliminator.

My question is that now I want to use the O2 optimizer and re install the O2 sensor what is the easiest way to put the sensor back in the pipe?

Remove pipe?

or can I get to it by removing the bash plate (i have an adv spec bash plate).

Many thanks
