I have a 09 model. Does anyone have the same noise I am experiencing.
Seems when I engage the clutch and place the bike in gear and release the clutch, it makes a whine type of noise. It sounds a little like a bashplate whine, but I don't have a bashplate fitted. Clutch acts OK, just makes this whine noise. Doesn't matter what gear I am in. It only happens as I let the clutch out and the transmission is driving. It is quiet when in neutral and just idling away.

Is this a common noise or is there a thrust bearing involved that maybe on the way out.

One guy suggested that it was the clutch springs. Another guy said that the lack of material thickness in the casings was a problem in transmitting noises.

Has anyone else experienced this noise and had a solution to it.

No replies to my post as yet.
Took the bike to a trusted old bike mechanic today.
He had a good listen to the noise.
It was only evident when the clutch was under load. Tried the clutch with bike in gear but the back wheel off the ground ( no load) and no noise. Soon as the wheel was on the ground and the load was applied the noise came back.
Suspicion was that the lash in the primary gears was greater than specs. How can this be? As the bike has been used at motocross a possible landing from a jump whilst under load MAY have slightly UN-trued the crank. Thus making the lash on the primary gears greater than specs.
I am riding a 2 Day event this weekend with the noise present. Will let you know how that goes. If the noise gets louder I will pull out the event.

After the event,(if nothing happens) we will disassemble the clutch cover and do some measurements on the primary gears lash and check for crank run out.
