They help a little.. The clutches on these are just that way.. Nothing has been put out that eliminates the rattle. I don't even care or let it bother me.

This thread is good info Just bought our new S-TX GT Friday, put 22 miles on thus far, love it! But, noticed that clutch disengagement noise? Clutch noise? appears to be this subject bolt noise. I just started new breakin... not overly concerned, have watched a few videos of same machines in the mountain snow - same noise. Only when driving - clutch disengaging? ... Will look into the bolt washers...

That's why I joined this forum. Thanks much to all. KR

The only way to quiet the OEM Yamaha Primary,[or drastically reduce noise], is Hurricane's noise reduction shaft[no longer available] or their noise reduction ring they still sell. Pretty pricey but I have had their noise reduction shaft on my 2019 SW since new and it is still WAY quieter then all my buddies SWs clutches.

No heated garage - we just bought it 3 days ago lol ..

Been out twice thus far ... noticed the clutching noise - the engine is quiet. The clutching noise is just 'different' that's why I noticed it and its not bad nor loud etc. No concerns, wanted to know what it was ... Dealer is great: I have 4 years Warranty

Its all fine I should add - I live in the North: its my new daily Winter driver 6 mths out of the year- around Town, at the Lake, Trails where ever lol, drive out from the house ... all I did was buy a new one My previous 4 stroke turbo was dated and sold...

Not much you can do to quiet the stock primary, but it does work well. Be sure to watch for roller/bushing wear over time. If you keep the stock tune you will be fine.

If you're running stock power an option is the Umatek clutch. I have a couple customers running them, they are very quiet.

I run the stock clutch and I grind the roller pins shorter so they don't slide back and forth and I also shim the buttons with Polaris shims to keep the clearance at the minimum of spec. I also use the knockout kit, but it has been met with skepticism. Personally I like it.
These mods do take time and may need upkeep every few thousand miles.
