    Loosing rear cylinder

    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.
    Don't believe everything that you think.
