I have some kind of noise that sounds like it's coming from under and behind the drivers seat. I never noticed it until I put the rear window on. It doesnt do it at idle, only when I'm moving. Sounds almost like a rotor on a car that has a little sand on it and you spin it by hand and you can hear that grit. Just over 200 miles on the machine and only been in small road puddles, nothing deep. Hoping I can get a video of it to catch the audio. Anyone know what I'm talking about?
