Primary clutch rattle-knock

[LEERIVERNYTRO]

Any one hearing a rattle/knock from the primary clutch area of their 09 xtx? Seems to be loudest at idle. Sled has under 2000 miles and warranty just ended in sept.

It's normal! Annoying....but normal! A trademark of the Yamaha triple.

You know I have been hearing a sort of rattling noise at idle, and wasnt sure if that was normal or not, its not that loud but you can hear for sure

I just had a dealer install a 0.020 shim behind the spyder which I read about on SnoWest. It did not take the rattle away totally but it did make it about 50 percent more quiet. The shim itself is worth a couple of bucks and an hour labor to have it installed.

Thanks for the reply's, sled is at the dealer today, I will let you know what he says when he has a look.

does it really rattel when you shut the machine off or just at idle

 

[LEERIVERNYTRO]

Most noticeable at idle. You can hear it when starting the engine as well. With the side cover off it is pretty apparent it's from the primary clutch. Not too loud when shutting down.

You would think that Yamaha engineers could develop a clutch that wouldn't sound like my cummins diesel rattling. They make everything else on these machines quiet, exhaust, motor and then they have a rattling ole' clutch?

 

[MT Nytro]

one more question does your clutch engage at the same rpm all of the time. my mtx had a rattle and didnt engage properly ended up being a bad bushing in the spider but not to bad to fix with the right tooling

 

[LEERIVERNYTRO]

Yes, the clutch seems to engage consitantly, sled runs great just seems way too loud.

To quote another TYER..."If it sounds like a bag of marbles under the left side plastic its normal". Normal for Yamaha's Nytro anyway.

It's from the 120 degree firing on the 4stroke triple. They are loud from day one.

 

[yamahahaha]

i know it is normal but y does it rattle?

 

[LEERIVERNYTRO]

Well dealer confirmed what everyone has been saying, noise is normal. Too bad ... I am sure the rattle has caused lots of people concern. Oh well deffinately not looking for trouble, enough seems to be coming along on its own.

Just bought an 04 warrior with a clutch noise that sounded like the thing was comming apart. It was idleing at 1000 rpm's. Could not change idle cause the jets were plugged. Cleaned the carbs and set the idle at 1600 and I can't hear it at all. Hope this will help others as well.
