Has anyone tried this?

So I started tearing the bike down today and noticed that the air intake system is different then how my CBR600 was. The front of the frame has chambered ports to flow the air into the airbox.

Has anyone tried polishing/ smoothing out the inside of those chambers to increase airflow and saw results?

I hope I didn't burst anyones secret trick lol :whistle:

even though there is some restriction in the headstock area, I think the Triumph engineers would have calculated this into the equation(s) for airbox tuning. This tuning however, is optimized for a certain RPM range. For a street machine this is almost always a compromise. without a bunch of physics calculations, you simply wouldn't know at what range this tuning is for.
You also wouldn't be able to tell how many gains(or losses) your modifications yield without before/after dyno time.
