With stage two cams in, the airbox was clearly restricting airflow bigtime. So I set to an old ST 1050 airbox with the power saw and die grinder.
I used a K&N 97/01 filter at the back of the airbox and moved the K&N std filter further down giving more volume inside the airbox. It sounds mental on full song, a definite improvement that anybody can do.

You can see how incredibly restricted the OEM setup is.
did you already test this? how much richer the mixute needs to be. or does the vacuum sensor make up for some of the adjustment.?
looks like there is so much filterin area that even one of those filters would be enough.

that is a sweet airbox, i have no idea what triumph was thinking when they made the stock one. those velocity stacks are sick!! I want some
The fuel tank is close to the rear filter, I just did it anyway just to make sure the motor is not choking. It's lean that's good, so it's working well, dyno time next week.Originally Posted by Jaket
