I guess I've been lucky, but the sputtering and whining started yesterday. I have a 2019 Trailboss Custom with 93K miles. I thought it was just a bad tank of gas at first, but there is also whining from what sounds to be in the transmission. It goes away when I drop the throttle, but comes back at low rpm. I've looked at the belts and they all seem fine. Oil and transmission fluid are good too. Anyone else with a custom that has had these issues?
