Noticed a little clacking type noise coming from the cvt area. Mainly just while deceleration.

I did get alot of water in the cvt about a year ago, drained the water and continued.

My thoughts are, possibly the weights, not having the correct amount of grease. Or something similar. It seems to not be too dirty though ;)

I will be taking it apart a bit more for investigation, but I have to work for a couple days.

Thanks for any advice

Ive made some progress in.
Does the grease look ok? From what I can see it looks ok. No wear marks on the weights, possibly like the dust has made it dirty. But I dont believe the noise is from this area.

From the sound of this being spun counter clockwise, im feeling the one way bearing needs replacement. As my engine braking has been kinda iffy...

You think the one way is most likely the problem here?

Grease looks ok. Have you ever changed it? If not that would be a good idea.

One way bearing sounds normal to me as fare as I can tell on my phone. As it has cams not the typical rollers.

Have you been feeling you one way acting up while riding recently?

Ive not replaced the grease. I will do that.
Its a noisy chatter coming from the cvt area clearly, that hasnt always been there. Engine braking does cut out pretty often more recently.

Im at 440 hours, of lots of rocky downhills. And thats when the cvt is chattery. While in nuetral, it sounds very quiet. Never noisy while on the throttle.

From a few videos ive seen, people seem to replace the one way and the noises go away. But thought somone might have an idea other than that bearing.

From your description I would definitely change your one way bearing sooner then later. Only use an OEM part, all aftermarket are junk.

While your at it pop in some Grizzly weights and a 1 or 1.5mm of shims for good measure! ;)

Definitely change the grease. It was ivory white when it was new.

Interestingly yellowish cream Yamalube grease, turns to grey after only 300-400 miles. Kinda odd.. So the grey is not necessary an indicator of age....just one of my observations over frequently evolving clutch mods earlier on.

Agreed. It must get dirty from The cvt air intake
