Default SV650SX curvy loud popping at idle

Is it an exhaust noise? If yes, then it's weak at the bottom end - a weak mixture results in slow combustion and is thus still burning when arriving in the exhaust often causing a popping sound. Weak could mean an intake leak, or carb blockage/obstruction.
