Hey. New to the sideXside world. Took my 2020 General out for its maiden voyage and found it was hitting hard on small rocks. Air in tires from dealer was around 14 psi. I lowered to 10 psi with no difference. After 50 km of riding it managed to rattle the doors loose and now they are vibrating. Wondering if that’s normal. Any advice. It was all hard packed trail riding.
