The whirling sound?
Mine does that and has for years.
Did you count the stock ratio to compare to the new ratio?
Start around 0:45 to hear.

0.5mm of shim is a waste of time, unless your trying to maximize the gains from machined sheave. Which is not the case here. Try it as is before changing things again. Even if it's just a quick ride around the block

@mainegrizz660 Vdeo is kinda short hard to hear clearly ..
At the end the noise seems to be the belt squeaking in the sheaves. Sometimes when the belt is removed then reinstalled it will need to seat again. Turn the CVT by hand you will probably hear the same

Did you notice the tension on the belt in the video, how the belt is mashed between the sheaves?
If the ratio is on, and the system turns by hand freely, you're good to go. This one reason I suggest to always count the ratio after tightening the primary nut and seating the belt. If something is wrong the ratio will be off.

Do like in the video, count how many times the primary goes around for one revolution of the secondary, and very very accurate. If something is wrong the ratio is most likely off, and if correct ride on.

The friction between the belt and sheaves will always create a squeaking noise. When the belt is worn in the sound will decrease.

There are noises you will hear without the cover installed that you don't hear when riding. As stated above, you should be good.

Lots of guys use an impact. I prefer to use a torque wrench and reassemble by hand so I know I've done it to specs. Just make sure the belt isn't getting pinched when you get to torque value.

The warning about using an impact is the vibration can shake the one-way and cause a problem, live and learn. And when using either tool don't let the belt take some of the torque value when tightening the shaft nut.
How do you count the ratio?
I did the counting in the video. I make the secondary and use a reference point to stop at, then go to the movable sheave and make a reference point for the counting. Then turn the primary enough to have the secondary make one exact revolution. The ratio is how many time the primary turns for one revolution of the secondary.
The more the primary turns for one turn of the secondary is more engine power (engine revolutions) for one revolution of the secondary, to the transmission to the tires.
