I have a 2020 KRX with 2,600 miles. I replaced the original belt at 1,940 miles when it started "chirping" at takeoff. I replaced it myself with an OEM belt. I cleaned the sheaves before installing the new belt. Now at 2,600 miles I'm having the same screeching sound at takeoff. It sounds like the belt is slipping.
Any one else having issues ?

I’d there any grooves in the sheaves? I also have an early 2020 and I’m having the whole primary/clutch drive replaced. Yours could have the same issue.

I didn't notice any grooves when I cleaned it

Check your tranny fluid, wet clutch could be locking up prematurely?

Look for grooving like this. We have also seen the arms groove as well.

Yep I have that problem

How often are you taking the cover off and blowing all the dirt and dust out of the clutch probably should do it every 250 miles or so.

My picture taken above was at 760 miles. It was actually really clean and I rode in the desert.

mine has 875 miles and i have blown it out 3 times unbelievable how much dust and belt dust that is in the clutch

I ride in the same terrain as you. I guarantee you stick the end of the air nozzle in the primary, you’ll be picking out black boogies for 2 days!!

 

[BajaBum]

Definitely but has to do some wear damage if not cleaned out

I've averaged about 150 miles between blowouts. It doesn't look bad until you start blowing and it is really dirty. Best do it outside and not in a shop or garage. Pretty huge dust cloud will come out. I've been told the Gboost belt seems to keep it cleaner.

 

[Jraoffroad]

Ya, that's pretty filthy.

I did, not much came out. But it is defective. I have also taken apart the pre filter and frog skin a few times to clean it out. It was really dusty in there. I’m sure that helped.

Pictures of my weights at only 350 miles.

You can see the soot in the channel underneath where the weight goes.

I used a magnet to install the new weights, instead of a screwdriver to line things up for the pin. I didn’t want to mar anything up.

If you look closely at my factory weight, you’ll see some pretty good pitting starting.
I have the beginning stage of a groove starting at the top of the sheave, so I cleaned the entire clutch sheaves real good with scotch bright pads and wiped them down with brake cleaner. I’ll keep an eye on things to see if it gets worse with the new belt.

Do you have an early 2020 machine

You might have a defective clutch as well.
