a rattle after getting off the throttle

I just had a question maybe someone has a little insight into. I have a 05 yz 250 two stroke. After snapping the throttle while sitting on it's stand, or whenever I let off the gas after a straight there seems to be a little rattle that follows. I was thinking it was in the motor but I'm not sure. Could be the frame? Just curious to hear if someones heard the same. Thanks

Go over your engine mount bolts and tighten them to spec. If your not sure if its coming from the motor or not, try going over all the bolts on the motor and if none need to be tightened, check your clutch / brake levers and see if they are the cause.

Could be lots of other things as well so just go over all the bolts you can if the above doesnt do the trick.

Let us know if you pinpoint where the noise is coming from.

My '05 yz125 had the same problem but believe it or not it was the washer on the pin that holds the rear brake lever to the pump

Levers like to vibrate and make that noise....

      Hey guys I just bought a bike last night. So the seller said the bike will turn on but then die. We didn't try it because it was really late at night and it was raining (seat was wet). But he said if you bump start it, it will turn on and ride. So what do you think the problem is? I just want to make sure it runs... I probably won't be able to bump start it till Saturday (rain)... It's a four stroke, and I know absolutely nothing about them. Thanks.

      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.
