Have had zero problems with 2018 RM. 7,500miles. Couple days ago Wife and I were riding and when I gave it a little throttle after pulling away from an intersection it stumbled a few times but smoothed out once I was past 2,000 rpm like it had bad gas but had already ran 100+ miles on that tank. After that it was ok until the next day. I had topped the fuel off and even though it ran smooth, it felt like it wasn't as responsive as it should be. I haven't had a chance to ride it again since then. Does it sound like bad fuel ? Any other ideas ?
