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 would on my race bike but it would make it not super stock legal. On the street bike i don't use all of its power anyway so it doesn't make enough of a difference for me to spend the time doing it on the street bike.
IMO, you don't gain much from doing this because the air filter is right behind the inlet, which restricts/slows down the air flow. Changing to a high flow filter like K&N is easier.
A " high flow" filter won't help if the neck and snorkel are restrictive.... I didn't bother messing with the frame, I just cut a big effin hole in the airbox :laugh::laugh:
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.
