I Have a 2017 PRO X/S 200 (ID 2B523957) It was running ok, but did notice it would sputter when first started in the morning then was fine the rest of the day. Then after setting under a bridge waiting out a storm, when I started it, it wound fire, run real rough for 5 seconds and then die. never would run. It even backfired once. Its at the dealer waiting to be fixed. Any service bulletins on this motor? Any speculations on whats going on? Motor has less than 50 hours, bought new last May of 2017.
