The only thing better than the sound of a carburettor opening is the sound of 4 carburettors opening simultaneously!

The bike has airpods right now. I'm not sure if the previous owner rejetted after the airpods were installed. Everything else is stock.
So will I have to rejet if I remove the stock baffles? What would happen if I don't (lean/rich)?
Thanks!

Pull the baffles and see how it does,if it runs lean (pipes turn blue) just enrichen it a little.You may have to re jet it anyway,but that would give you an idea if it only needs a little or none at all.Probably will with those pods tho.
So why do you want to remove the baffles for??..make it louder?...thats about all it will accomplish.

Removing baffles may result in leaner operation, especially at higher rpm.
Best indication for proper mainjet size is plug reading after a high speed throttle chop (cut ignition at same time and bring to stop). To assure valid plug reading, should be done after assuring correct valve clearances and good quality spark with correct ignition timing, and clean free-breathing properly oiled pods.
Might be able to compensate for any mixture change needed in the pilot circuit (without replacing the pilot jets) by adjusting the side located pilot air screw (turn in clockwise to enrichen the mixture, by reducing air OR turn out counterclockwise for leaner mixture, which allows more air).
Good Luck!

Thanks for the insight! This is something I'll probably experiment with next weekend. I only wish I had the time to during the week.

As known, the carb pilot circuit mostly governs the lower rpm range of operation (from idle up to about the first 1/4 of throttle opening).
When doing the high speed throttle chop, usually the bike is pulled to a stop in a safe location off the road so the plugs may be removed and inspected. And the plugs are HOT. Here's a tip -- remember to carry along suitable plug removal tool, and a short length of rubber hose which fits snugly over the plug to allow easy removal and replacement of the plugs without burning fingers.
