2006 crf450x clutch issue? Help!

I been through a few threads on here about clutch noises, but nothing that is directly related to CRF's. First of all, I've already did an oil change to see if that was the problem, but the noise is still there.

The noise is like a clank or knock, but it only happens when I'm not pulling the clutch lever. When it's pulled in, even the tiniest bit, the noise goes completely away. Some of the threads on YZ's and YZF's say it's normal for some Yamahas to do that, could it be normal for CRF's too?

I change my oil every two rides and i'm very particular about keeping up on maintenance. I haven't owned the bike long, but I swear I can't recall ever hearing this noise. Please help.

The clutch is always noiser, and there is more vibration, when engaged.

So are you saying this is normal?? Any ideas what could be causing the noise? My best description is sounds like a throw out bearing going out in a car but quiets down when clutch is pulled in.

On a 2006 with unknown history that you just got, I would pull the cover and have a look.


Could be anything really; broken spring, notched basket, worn bearing, etc.



Anything you would have to split the case for??

Not if it's the clutch...that's all under the right cover.


Things that would require splitting the cases are:


1. Tranny

2. Crank

3. Bearings

4. Oil pump.


Everything else is outside.


That's why I said it wouldn't really hurt to look.  Pretty easy to do.


 It may be nothing as Krannie said, but if there is a problem, it's always better to catch it sooner rather than later.


 But I have to say, I'm not sure anything described as a "clank" or "knock" with the clutch lever out would be normal.  Sounds like something has some slop that should not.  Everything should be tight and engaged with the lever out.


 You might get some noise out of the needle bearing if it's worn with the lever out, but that's not something I would say would sound like a clank or a knock.  Would be a constant noise.


 More than likely  you have a worn hub, basket, or plates and with the clutch lever out, your hearing the plates go back and forth.  You would hear a knock or clank every time you took off or slowed down, and it would disappear when you pulled the lever.


 Obviously though were not there<g>

Thanks bro the noise is constant and Its definitely not a knock or clunk. I wish I could describe it better. I'll pull the cover off during the weekend and see what parts are worn. Thanks again

So are you saying this is normal?? Any ideas what could be causing the noise? My best description is sounds like a throw out bearing going out in a car but quiets down when clutch is pulled in.

So its a shrieking squeal?   

No. No shrieking squeal either almost like grinding but I wouldn't call it that either. maybe I'm just paranoid about it.

Sounds like the stock noise


Kind of like an old  washing machine on spin cycle, when you release the lever....?

Yes I would say so. Ok to ride or no?

  On the clutch lever when you pull it, are you going all the way?  or are you saying it's a slight pull, like 1/8 of an inch and the noise stops?


  If the later I would think a worn needle bearing.   If not, then the usual clutch noise.


  I think I would still have a look though....initially you said you don't remember the noise before and now do, meaning something changed.



I think you are fine.


Having said that, if you are really worried, try and do a video of the issue, and post it.


You will have to transfer the video to Vimeo or Youtube to be able to post it.

Great thanks for all the help guys I'm new to the thread and new to the crf450x as well and love it I had a suzuki rm250 before. I can say I don't miss the 2 strokes haha

      Anyone having or had problems with the starter not turning over easily on the 450X???
      I have read about this problem on CRF's ONLY and not seen anyone come up with a fix.
      Problem being is that you think there is a problem with the battery, when infact the battery is OK. When you have a good fully charged battery in the bike and press the e-start, it turns over very slowly.
      I have checked the electrical circuit and it seems OK. I am wondering if it might be the starter itself - any suggestions?????

      I've studied the Jetting sticky's but still have a number of questions:
      I bought my '06 a couple of years ago and had a smog block-off kit installed and the pilot jet was upsized to a 48 and the air box opened up top only. The bike has appeared to run a little lean at times and got hot on a couple of occasions in elevation and on one other occasion. I'm looking at upping the main jet to either a 165 or 170 to help with the possible lean condition. The bike currently has a 142 main jet in it which I believe is the stock size. It looks like the most widely used Needle Jets are the JD Red, but it doesn't look like they are sold separately, is this correct?
      I was going to also get a 45 pilot to have options for further tuning. My assumption is that every bike is a little different and that where you ride is going to have a lot to do with jetting. We ride mostly, mojave desert, baja, and southern Utah with elevations from sea level to 9,000 feet but the higher elevations are generally for a short period as we generally continue through the peaks and head back down.
      I'm looking to convert from a stock exhaust to possibly an FMF Q4. I want something a little throatier but not overly loud and will provide a balanced flow of intake/exhaust.
      So can I get the JD Red Needle Jet by itself or can I get by using the stock and move the clip and be just as happy. I'm just looking to enhance overall performance of the engine and maintain reliability.
