Re: '97 cbr900rr airbox mods
If you want to make it into a track bike I'd recommend putting the airbox on it.
You could run pod filters but it can be a bastard trying to jet carbs when they're sucking air that's moving past the bike at anything from 20mph to 150mph. The airbox grabs air and slows it down to a consistent velocity.
Certainly try the pods if you really want to avoid the airbox but let us know how you get on with them.
