Unless I raise the throttle off idle quite a bit, the engine appears to hesitate or stumble. The motorcycle is a 2017 fuel injected C50T with about 3000 miles. The previous owner said he had the motorcycle serviced by a mechanic at about 1000 miles. I know the oil filter was changed since there is a K&N filter installed. I don't know if the valves were adjusted - I doubt it. Your thoughts? Take it to the dealer for the first maintenance service?
