Okay I have a 2010 yz450f and a 2009 yz450f neither one of them do it and on the new bike it's just like clutch chatter then pull in clutch and noise is gone

How come all of the bikes I own do it.

Gotta love when people ask for advice and try to bust your balls arguing the very advice they asked for.

Take it back to the dealer if you are worried about it. Don't reach out for help then question the FREE help you're offered.

CALM DOWN!!- The guys just worried about his bike and rightly so! Now I'm not doubting what Grayracer513 said but I will say my 16 yz450f doesn't have that noise he's talking about and neither did my 07 yz450f . I do agree with you....if he's worried about it take it back to the dealer.

It's normal, and they will all do it, at least once they're warmed up.  In fact, the '08 got a modified primary driven gear to reduce the noise.  Didn't make it go away. 

 

Those who say their bike doesn't have simply never noticed it, or they should consider using a different oil that isn't so thick.  It's not loud, it's just there.  Most people don't freak out about it is all.

Well I'm pretty good at diagnosing complaints on equipment and hearing noises, but I'll see if I can hear what your talking about on my 16 450. Then again I'm turning 50 in a few weeks and getting deaf in one ear and can't hear out the other!

Ok I'm down at Pala Raceway and I stand corrected. I can hear difference when the clutch is pulled in...definitely nothing I would worry about though.

One of my 450s had a fmf q exhaust. The muffler quieted the exhaust enough so you could really hear what a rattletrap these YZFs are. Of course none of the noise was ever an indication of anything wrong.

My 16 does it too. It's done it since the day I brought it home and I've never had any problems.

A lot of cars with 4 cylinder stick setups, even the occasional 6, will exhibit some degree of the same torsional rattle.  Some of GM's 6.2L Diesel stick shift half tons were almost impossible to sell because of it.

Ironic I jumped on here to research this. We pulled my clutch cover off today while riding because my clutch sounded bad to my riding buddy's. I have a 14 yz 450 and the clutch is almost new with 4 rides on it. It came from a 16and the owner wanted his recluse in the new bike and put the new clutch in it before I bought it. I use 20w50 since that's what the original owner used. It's fine one idle, when I pull the clutch in it sounds like something is loose in there. Everything looked good on inspection though.

You have the opposite symptoms, though.  If it gets noisy when you pull the lever, look at the inside of the clutch cover for evidence that the Rekluse pressure plate is hitting it.

You are right...The Rekluse isn't in it anymore?  Any ideas what that could be?

Hard to say, but what you'd look for is something that starts turning or comes into contact with something when you pull the lever in, so that's the pressure plate vs. the cover, or the release bearing in the end of the push rod, something like that.   Calls for an inspection.

 

Again, that's the opposite set of symptoms from those originally reported here.

I bought a 16 yz450f a month ago, I know exactly what sound the op is talking about, if clutch is engaged (with lever out) it is a sort of grinding sound, pull lever in and it goes away. I came from a honda 450, not used to a clutch sound but am super excited at how yamaha engines don't sound like a bag full of rocks getting beaten by a sledge hammer. Normal noise, I think it's growling at me to get in gear and haul ass! I use amsoil 0-40 4stroke oil, if I used rotella like I did on the honda I'm assuming the noise would quiet. Thing is....there's less oil in the entire yamaha engine then my 08 crf450r engine oil. I'm not comfortable with THAT yet.
