I just recently got a 2008 S83. Has right at 20k miles on it. It sat at the dealer for about 3 months without running, started and ran ok
Just had a shop install a set of Cobra 2 sided slip on's. K&N filter and rejet with a stage 1. Shop called me today- from 1/8 to 3/8 throttle it is loosing the rear cylinder. 1/2 throttle or more it runs like a champ. They pulled the carb and rechecked and balanced them again. Idles fine and above 1/2 throttle but still dropping at low throttle. Open for any other ideas? New plugs installed already.

Find a different shop.
Certainly sounds like a carb problem and the only way to figure this out might be to UN-do the changes one at a time.
I would start by putting a stock air filter/air box back on it......because that's the easiest thing to change.
Then carbs back to stock.
I personally don't have much sympathy for people who think they are doing a good thing by making more noise and defeating the engineering of the engine builders.
It turns out bad more than most riders like to admit.
