Yup. Did that on my old '04 Bonnie. Super-easy. Took me about 3 beers from start to finish. There's a way to wiggle the air box out of the frame intact, but it was like a fucking puzzle. Had to hacksaw it. What year is your Bonnie? Carbs or FI?
Best thing you can do to those bikes. Pipes alone don't make much difference. But rip that air box out, rejet the carbs, and then add the pipes. It was a whole new bike after that. Absolutely worth doing. But don't get caught in a heavy downpour. The pod filters can get soaked and choke the motor.
Ditched all the emissions crap, too. When/if you do this, keep a handful of the rubber vacuum caps in your jacket. They like to harden, crack, and fly off the intakes at the worst times. A dab of blue RTV can help keep them in place. But be very stingy with the RTV. A little goes a long way.
I also dropped progressive springs in the forks. Upgraded to Ikons in the rear. Clubmans, bump seat, lowered gauges and headlamp.
Did it all myself with no special tools. Go for it. It super-easy. You can do it.
EDIT: I sold the bike years ago, so I can't remember the jet sizes I used in the carbs. Triumphant.net has a million threads on air box removal. You can find the pilot/main jet sizes there.
