That's a strange answer. Maybe your front hood stops are misadjusted. That is, the hood front corners are not resting on the stops, thus "flutter play"Direct experience.
Maybe you have water in your hood to stop the flutter? I know my 2019 pooled water inside from those badges.
If the water level gets too low, the 30 wt ball bearings fall out. Buy a bag and add them at the fetzer valve and it'll be like new: only a minor flutter at 80 mph.I like the idea of adding more factory water. I used spring water but it must be lighter than the factory fill.
