Speedy recovery
Honestly, hiway and (some of) the Yamaha techs have it right. We can argue theory all day long, the proof of the effectiveness of this mod will make itself clear once we get a good wideband reading.
There are just too many variables to "know" what the result is. And to throw another wrench in that, the readings will also only be specific to HIS bike, since it will also have its own set of variables.
Air velocity, density, temperature, atmospheric pressure, flow pattern, motor build tolerances, break-in procedure, humidity, load, and ambient temperature will all (among other factors I'm sure I'm forgetting) effect the outcome. So, the tech who said each bike will react differently and you need to monitor your own to properly judge the safety of the mod, I think, had it right. Sorry, there is no easy answer.
