Dead spot in throttle

Hey friends I gotta question, I’ve got a 2013 outlander 800r, I’ve got a dead spot in throttle at low rpms it feels like the throttle is struggling for gas, it goes back n forth it feels like the old carburetion and a bad govenor, does or has anyone got any experience with this? I just got the break in service done and asked the dealer to check it out, they adjusted the cable but still have this issue.
