Hi all, recently bought my first Triumph (used 96 Tbird). I'm scratching at the garage door waiting for the weather to warm up so I can start enjoying my new ride.

When I removed the airbox cover I noticed the previous owner had removed the aux air chamber. My searching on this site tells me it's the first part of the two chamber air flow system. How critical is the aux air chamber? Anyone remove it permanently and ride w/o? Does installation of the K/N system require removal of it? My bike has a few aftermarket mods so I'm wondering that has something to do with it???

I am thinking that you wouldn't need the second chamber if you have K&N air cleaners. But, I can tell you right now, I am changing out my air box as we speak, and I am so frustrated that I could kill small furry animals right now. lol

It should be there, even with a K&N filter element installed. I imagine that it neing removed will have a detrimental effect.

The other problem I can see is that the seat lock bolts to the aux. air chamber, and if the lock is missing, what is holding the seat on :???:

Ok, my bad. Sorry bout that.

Actually, it doesn't have a K&N I was just thinking perhaps the previous owner had installed a system but removed it prior to selling. The seat lock is fixed to the upper portion of the aux chamber. Hopefully that doesn't go airborne at 65 mph :-D

Airflow would be negatively affected and you will probably hear more intake noise. I hate to think what Triumph wants for one but it wouldn't hurt to check. After that try finding one used. Several people on this board have modified their intake system and may have one available. You could also try some one like Baxter Cycle.

The air box under the seat (not the filter box on the carbs) performs two functions: initial air filtration and noise suppression.

It creates a low-velocity area where particulates in the air stream (grit, water) can drop to the bottom of the box and unless you're in an area prone to dust/sand storms, it's not necessary.

Here in Minneapolis it's only useful as a nesting space for small rodents.

Installation of a K&N filter doesn't require removal of the air box since the single-inlet Classics air filter box provides more than enough restriction to limit engine performance.

If your bike is from California this box will contain the emission control filters. These bikes have a slighly different vacum line routing also. When I removed my EC filter, the name on the side of the filter was honda. I read somewhere on this sight someone converted this box to a tool box not a bad idea. :-D

Gee, I wonder if you could insulate it somehow and use it as a mini cooler? Just a thought. :razz:

It was me.
I have a small mesh over the hole for exclusion of field mice on the main airbox intake. The auxiliary box now cotains a tin of 'flat mate', a few cylinders of CO2, a sidestand support in the shape of the Isle of Man and a cloth to supress the rattling.
It made absolutely no detectable change in performance, the only difference was when I tried to get clever and drilled a similar size hole on the other side of the airbox. It then ran like a dog, big hole in the midrange which I fixed with duct tape. If you go the whole road with speed triple cams, etc you could do with an extra hole but the standard bike prefers just the one. :-D
