Herb,
Take the seat off and the snorkel is right there. 3 bolts hold the cover over the air filter and the snorkel fits into that cover. It will come right out of the cover, leaving a hole roughly the same diameter as the inside of the air filter. Now the intake can draw more air. With the cover in place, you still have the filter sealed so that only filtered air goes into the engine, but now there's a lot more..
If you remove the cover and the air filter, stick your fingers in the holes between the airbox and the carbs. There may be 2 other rubber pieces in there that can be removed (just yank them out, I'm told..) to open up the airflow even more. My '03 TA didn't have those pieces, so I'm just repeating what has been said on the boards before.
Both of these actions are reversible, so try 'em and see if it makes you happy. I'd do one at a time, put some miles on the bike, note how it starts, how it accelerates, etc. and keep an eye on your pipes. You will be adding more air to the mix, you may then need to add more fuel to keep it from running too lean.
And that's a whole different can of worms..
