Knockout kit

[PowderFalcon]

After 200kms, all the clutch noise is back. Knock out ring is JUNK.... but worth a try for $55 I guess. Do NOT Recommend.

I know this is going to sound crazy. But the clutch noise never bothered me, never even gave it a second thought. So for the cost of a dinner out, I thought alright, I'd give it a try. And now that I understand what it's like to not have the noise. It's making me crazy haha. Doing my best to see to it that it's taken care of, one way or another.

I have not been bothered by the noise. A small earplug in my left ear eliminated the noise. LOL

Have you check to see if ring came off?

I use ear buds....lol.
It seems as thou riding in colder (0°f) and keeping the RPMs down to cruising helped to cut down on things (Noise) I'm sure it makes some sense.
I'm making one last ditch effort at a 90% cure, for all riding. But it's only for the satisfaction of trying.
A bud sent me one of those quite kits. (Copper washers) to take up some slack in the roller pins. And I have a different Snubshaft. Just waiting on a seal.
But like you, Upstater57...what difference does it make. It's not the end of the world.

I've put over 200kms on, all good.
As I pointed out, the rings should be a few thousandths larger as they don't fit tight enough.

Yes I do agree I had to press mine in. I only went 45 km just a shake down to check sled over but no noise doesn’t even sound like a clutch is on it. I hope to put some k on this weekend if trails hold up.

The ones I’ve done all required a press to install them .

The one thing that occurs to me about the green locktite is that cure time is critical. I just looked up the TDS and they show 24h at 22c (~70f) to full cure. Just running it won't work because it may slip prior to curing.

I did one yesterday and it slid in with my hands, yikes.

Absolutely. The loctite needs time to fully set. Also, very important that all oil residue is removed on both surfaces.

I'm open to being proved wrong, but so far so good.
I hope that the guys that are are installing these on higher mile clutches realize that it won't remove the noise of a worn out clutch.

Well, there ya go. It just cut its effectiveness by 50%, possibly higher.

The effectiveness is still 100% as it is not designed to reduce the noise of the rattling external parts.

Copper washers huh, must be different thicknesses to accommodate the roller bolt being longer then the roller bushing, and causing that bolt head to hit on the clutch and eventually wear into that aluminum clutch. I found some steel washers that were a bit too thick at the hardware store. I then sanded each one down to allow .002-.003” play when fully tight. I was aware that if I went with one too tight, it could have caused that clutch pocket to move in and crack. Afterwards I learned on here, that I could buy some fiber washers to put on other end of that bolt to help absorb that hit/noise caused by the factory loose bushings/ bolts. Yes it does reduce some noise, but it still a noisy clutch. Mine were worn bad, on one of them I didn’t have to sand that steel washer to give it that bit of play. Hadn’t I done that it would probably have an 1/8” or more of play! Yep, these clutches should have simply added the set screws to the roller bushings!

I like the fibre idea...Yes, one in each side. If you Google "Yamaha sidewinder quiet kit" I believe Ulmer's sells them for $10. But please don't quote me.
