This is purely an experiment at this stage, once the bikes back together then I can get some data off it and adapt accordingly.
I have 2 backup plans depending on where the dyno shows I am.
As you say, if I need more air then I can either take half the top off the airbox and use the same idea which would give tonnes of air...
or my personal plan 2:
Where I have cut the inside baffle out make a filter to fit flat inside there, that would then free up the back part of the airbox for tools etc.
If I need to restrict the air I can place a flat bit of plastic under the mesh on top of the filter.. so this way I have many options.
My first idea before I came up with this was to use 54mm rubber pipe to come straight off the rear of the carbs and then have the K&N Pods INSIDE the airbox with the top cut off completly.
I just think this is easier, neater, and certainly cheaper

Watch this space for the results once the 904 kit is on.
I intend using 150 mains to start with and work on from there.. its exciting aint it
