Rattley Nytro primary clutch

[Thistledoo]

Well my clutch seems to be gettin quite loud. Noticed it today for sure as my buddy with his MCX apex pulled up alongside with no side cover and its quiet...like nothin. Theres no diff between these clutches is there?? Anybody got a fix?? I think its louder now than when it was new for sure....I can even hear it when riding with my helmet on. Seems to work fine.....just to noisy!!!

NOISY! that is the only way to decribe it. Mine works fine but it is noisy! My dealer is usually on top of things, but he has not heard or seen any fix.

any fix is temporary. I have seen a huge variation in yammie 4 stroke primary clutch noise. They can be amazingly noisey but it does not affect the way they perform.

its the harmonics of the 3holer makes the clutch rattle i just use o-rings on the weight bolts thats what is rattling.

 

[mmaxcarver]

Probably more noticeable on the 4 strokes due to they run so much more quiet???? My Viper was a little noisy also, just keep it CLEAN and don't worry about it..............

 

[drinkwyo]

Same Here

Mine is a bit noisy too. Was worried at first, but seems to be fine

 

[switchback]

There was a thread about this earlier this winter. Normal.

Mine's the same way...there was a fix for this on the RS models, atleast there was on the Ventures. Can't remember from the top of my head what it was, but my dealer told me no fix yet for the Nytro....

 

[firecat99]

yeah i asked about that when i first bought my sled, and they say they get louder when you clutch it, so im not to worried 1000kms and shes still together lol just stupid loud thats all, cant notice it when riding or when you bring the rpms up it goes away

 

[tivoklr]

Normal

Same sounds come from the primary on my 96 venture, but you can barely hear it over the engine noise.

Seems like having a quiet 4-stroke allows for hearing ALL the rattles, clunks, etc. that a sled creates that were inaudible with the louder exhaust on my 2-strokes...

Such as life, I think it's a good problem to have.

All the Nytros are noisy. Mine's really noisy, doesn't help that I took the foam out. I think it's to do with the 3 cyl engines as the Vectors were noisy as well.

 

[Linc]

If you take the clutch off,it's nice and quite,but the combination of the way the stub shaft attaches to the crank and the loose spider,it makes a rattling noise at an idle.

In order to improve market share the factory engineers were ordered to make the machine more like their competitors
After repeated attempts the engineers were unable to make the rings flake, crank fail, piston's to seize or even get the belt to explode
So in the end they decided to make the clutch rattle slightly

^^^^^^

hahahahhaha

 

[obr]

LOL...

I think Linc hit the nail on this one...I checked it out, and that was what I was told too....I don't like it, but....I think I can live with this..no big problem really, just annoying...

 

[Thistledoo]

Mines drivin me crazy....is there any way to quiet it up some?? Is it the weights floppin around?? Its not the pin that holds the roller...I know that...the slop on them is gone. Crazy when your sitten beside a apex and its dead quiet then you pull up on a brand new nytro and it sounds like the valves are floatin.....gotta be a fix???????????

 

[Linc]

You can get a bit of relief by having the spider shimmed,you'll have to take it to the dealer to have the spider spun off then put 20 thou shims behind the sliders.

Linc, so the primary shim won't affect the secondary, because of all the float it has?
