Stock H2 vs Mild Port w/34mm Carb vs Added Inlet Box

So.......there have been discussions about now a 500 makes more power in low end if tubes are installed. (Joe-Battleax) 

I did my part of the "investigation" and dynoed the bike from yesterday again today, but with the use of the inlet rubber and stock air filter box. 

Joe seems to be absolutely correct. I noticed same tendencies on this ported H2. 

Below are the 3 curves: When stock, after port work and 34's, and after port work 34's and with stock inlet rubber and empty airbox (with filter inside, it is too restrictive) 

LOOK CLOSELY.....now the ported has exact same power in low end as stock, or even a bit better. Power increased versus yesterday's test. 

And yes, I tried this back and forward 3 times. The power increase versus non inlet rubber/box and no filter at all showed up every time.
