hello all. i have never bought anything but honda atv's my whole life. The commander is a whole new world for me. my question is, i have a roof, visor and windshield installed and currently on a trip. Its running great but around 40mph you can hear the system whine a bit and then quit after 40ish. and nothing before 40ish. im sure sound is amplified with roof etc, and prob normal just need to confirm it. and just like letting off gas around and higher speeds. whine and prob normal with everything speeding down? runs great and love it. just never had a cvt setup.
