Noise at 40 MPH

So I hit the Infamous 67mph limiter today and I got to say that Is plenty of speed.

i noticed right around 40 mph I could here a mechanical sound engaging.It sounds like something is rotating and clashing faster and faster then eventually goes away at around 45-50.

I reduced speed and tried it again and sure enough the noise was there. Noise appears to be coming from the floor board in the center console. Maybe the drive shaft? Have you all experienced this noise?

Bump. Seeing if anyone is experiencing this. Doesn’t seem to affect performance.

Not experienced this. I have pushed rev and on, multiple times.
Biggest issue I have is at 38 mph and above
Front LED light bar whistles.
harmonic vibration of floor pan?
It’s definitely something mechanical, I’m leaning towards the drive shaft. There’s 1 other user that had this problem. I’ve messaged him. Looks like I might have to remove the skids and check
im thinking you would have a easier time removing console and passenger side panel.. set all 4 on stands and run it up and see if you have a bent drive line.. also check slip joint and ujoints for play.. don't rule out the possibility of a bad tire.

There’s no access from the center console to the drive shaft.

you can most certainly remove interior panels and view the drive line and water lines that are routed next to it.. just a suggestion to see if this is an obvious source of a vibration.. pulling the skid plate can be a pain if he has no intension of pulling the drive shaft... but hay have it your way pull every attaching panel off down to the frame if you want..

It’s a lot easier when you have a 2 post lift!
I installed a light bar, and now I hear a whistling sound above 16mph.

Last ride the sound was not there. All I did was take it home, unload it, wash it, install the light bar and it sat in the garage for a week until this weekend. Under 16mph there is no noise.

Is this the light bar making this noise due to wind cutting between it and the roof or is it something else.
sounds like you've answered your own question?
Well, I wasn’t sure if something was wrong with the clutch, drive line, or not. Because it was 15 miles today before I got over 16mph. Group ride with over 50 utvs. So wasn’t sure. Also wasn’t sure if someone else did experience this, what they did to remedy the whistling caused by the light bar.

What brand of light bar do you have? I installed a 42” curved nilight amazon special and have zero noise issues. Lights up the dunes fantastic too
I have a nilight 42inch curved light bar as well with Kawasaki mounts.

Went for a night ride about midnight last night after everyone got back. At about 45mph it gets really loud. Was able to put my hand directly behind the mount and push on the mount on driver side not sure if I diverted the airflow or what but that makes it stop.
I put my rig up on a Toy up rack on my truck and the whistle gets annoying going at freeway speeds...
maybe ill try a piece of duck tape on the ends..

Sounds like it might be the mounts. I have the EMP mounts.

Yes I have been hearing the same noises from my 2021 krx 1000 trail Edition. I've had the dealer look at it and they didn't find anything. The noise is exactly as you describe and becomes ear piercing loud the longer I drive it. PLEASE let me if you figure out what it is. Thank you
