HI. My new 570 has what sounds like a gear whining sound. Its not that loud. Almost like a diesel turbo sound. I can hear it basically all of the time in Low gear. In High gear I can hear it very quietly until 30 MPH then it gets louder. I am not sure if this is normal or not for the 570. It happens when slowing down, speeding up or holding a steady speed. It does not seem to be RPM related.
The machine is about a month old. 9 hours on the clock. 160 miles on it total. I followed the belt break-in instructions. I followed the 3 hour instructions. I have been following the 25 hour breaking requirements as well.

I can say that my 2020 450 HO makes a similar sound when slowing down.

Do they share the same transmission or do they have a different type of gear?

Any Ideas or suggestions?
Thank you Jim

We're all still trying to figure out what he did with the money his mother gave him for singing lessons
