So when doing my service I decided to remove the resonance chamber from the manifold.

Here is a picture of the box itself when removed:



I found a plastic plug in the garage that had the correct diameter as the hole:



I trimmed it down both to fit the hole and also the length of so it does not interfere with the airflow:



After that I but a strip of gaffa from the inside of the manifold and filled it with hot glue:



Before the glue settled I put the plug in and afterwards I removed the gaffa strip from the inside.

Here is the end result:



So now I have got a induction path to the throttle house that is smooth without any obstruction and also some less weight.

Mostly I have done this because I hate stuff on the bike that has no use and take up weight and space. If it will make any difference to the performance in any direction I do not know. But since I have a stage 2 filter and drilled airbox with the snorkel removed I think that the resonance chamber is not needed.
