So I’m battling quite a couple things in this topic. Here’s what info/experience I have so far. I have a horrible noise, so dealer replaced primary sheave and entire clutch assembly. Noise is still present. There’s another member that had his replaced as well and the grooves came back. He said they are updated part numbers but still have the same issue.

Just dropped my machine off again at the dealer. This will be the second time they will be replacing the clutches if Kawasaki will let them. We shall see! I am wondering if maybe the clutches aren’t the problem and the belt is… anybody using an aftermarket belt with clutches that aren’t grooved?

One thing they don’t tell you is the parts being replaced have a 90 day warranty. I think the grooving happens with all belts.

Have you run your finger over the pulley? Do you feel any grooves?

I have an early 2020 and did notice a little bit of the rings, but the sheeve felt smooth. After about 400 miles I switched to the BadAss belt and now I have no more "rings". I have about 1200 miles now.

I think the stock belt is too stiff.

Thank you @Krawler for that info. If they replace my clutches I am going to put a badass belt on right away. Probably an RCOR clutch kit as well.

I just put a badass belt on mine as well. Figured why not give it a try and see if there is any noticeable difference. My sheeves are still fine with zero grooving and around 800 miles on it. Build date 10/2019 It makes since that if the OEM belt is super hard that it could play a roll in sheeve grooving. I also believe that belt break in and riding style play a role in it as well. Who really knows???

I recently replaced my clutch weights and belt with RCOR weights and badass belt. My primary had the same look, mostly smooth, VERY slight groove up near the top. The new belt and weights seem to have fixed all the problems. I'll pull the cover and reinspect after a few hundred more miles to see what the sheeves look like then.
