SN 2B534669 2019 250 ProXS Optimax. I started to get a high pitched rattle at top speed and RPM 5500 -5900. I thought it was the power poles or the cowl latch or the small square covers with 3 screws but I couldn't say it was any of them after looking. What else rattles around the cowl? I can't say it's a motor issue just yet since it ran perfect for a 20 mile run other than the light noise.
