Strange squealing noise

When i shut my bike off (yz125) the other day I heard a weird squeal. It was in gear, clutch pulled in and stopped. I cranked the bike and it sounds normal in neutral. I noticed it when riding but thought it was just my front brake. Ideas? It's loud. NOT normal.

does not make the noise while running in gear with the clutch pulled in.

A bearing maybe... Ive bent my CS sprocket cover before that would squeal but only when I was almost stopped from the chain rubbing it.

Also had a buddy that had an impellor bearing go bad and the only time it could be heard was when the bike was shut off because it couldnt be heard over the engine noise. That was a grinding noise though, not a squeal

Well, it just so happens that there is a tiny bit of trans oil that has leaked from the weap hole on the impeller. Like 1 drop...

This is weird. I was abusing the clutch pretty hard and I've heard the clutch make noise when it gets really hot but this acted differently.

Might just be the impellor bearing. hmmm.

Thats where Id start... cheap and easy and doesnt require any significant $$$ to do. If thats not the prob. nothing lost but a few bucks.

Thats an odd noise to be comming from the clutch. The clutch seems to make a distinct noise when its hot.

it seems I've been riding the bike for a while rather low on trans oil too. that bearing probably took some abuse. not sure where the oil went though.

Not offense but thats why it needs to be changed regularly! I change mine every 2 rides which is probably over kill but I dont wanna take any additional chances on my race bikes

      Hey guys, 
      I've used this forum as a "guest" for awhile now and I thought I'd share my build now that it's all coming together.  The primary purpose of this project is to help me train for roadracing my 2009 R1 at lower speeds as well as giving me a cheap alternative to racing the big bike. 
      Here's what she looked like when I picked it up from a local shop.  Paid $800 cash for the bike as you see it with 17' rims, FMF pipe, EBC 250mm front rotor and clip on handle bars.

      Fits PERFECT!

      Shake down run at the Herrin Compound last summer:

      As she sits today:

      i bought my yz125 from a dealer and they said that the clutch was broken so i bought it and it worked fine it would run move and everything and then it started to act up and now only first gear works barely though. when you put it in first it acts like its bogging down but its not and when you go into gears 2-5 it wont move i dont know whats wrong with it im assuming the clutch is slipping or something if you know please leave me a comment

      Hey guys, I have a 2003 cr125 I bought a couple weeks ago and I'm having a problem with it. The spark plugs die every about 15 minutes, with hotter plugs it will last about 45 minutes. I herd that if the timing is off it can over heat the plugs and burn out the the resistor. Is there any truth to that? The reason I thinks it's not fouling is because when the plug dies it gives no spark no matter how much you clean it, And it shorts out.

      Hi all, First post here. I need some help.
      Ive just bought an 05 yz 125 for a good price but it needs some work. One of the forks has some pretty severe pitting of the chrome on the stanchion towards the bottom near the brake caliper mount.
      Ive found a pair of good condition forks from an 04 yz250 for a very good price, from the research ive done its seems that both the 04 & 05 forks are 48mm but are different, with the 05 fork regarded as being better than the 04, but not as good as the 06 + sss forks.
      Im looking for the cheapest way to get me riding, Will I be able to make the 04 forks work with my 05 triple clamps, brakes, wheel, axle, spacers etc? If not does anyone know what hardware id need to make it work?
      Finally, as a last resort, does anyone know if i could swap the stanchion from the 04 fork into my 05 forks?
      Thanks, Andrew

      I bought a 2006 YZ250, have ridden it 5 times.  It needs some tuning, but I am not sure I'm keeping it so don't want to spend much on it.
      Has fmf gnarly expansion chamber and turbine core silencer.
      I ride about 1000 feet above sea level.
      I'm going to clean the carb and check the jetting.  What is a good jetting for me?  85 main jet?
      Also check the reeds.  Is there a big difference between getting aftermarket reed cage and reeds or just getting a cheap aftermarket set of reeds that fit the stock cage ie.  Boyesen Power Reeds?
      The other things I'm going to do is permatex all the joints in the exhaust system and a compression test.   It was 220psi 5 rides ago so I'm guessing itll be fine.  Its bogging a bit but I'm thinking its carb and definitely exhaust joint related.  
      Let me know if I'm overlooking anything that could make the bike run crisper and more bottom end without throwing much money on parts
